Tuning Water/Meth with Speed Density
ฝัง
- เผยแพร่เมื่อ 30 ธ.ค. 2018
- I was going to call it, "Water Methanol Injection EFI tuning with Speed Density at the 26th Annual DSM EVO GT-R Shootout", but it's too long. Don't worry... I only talk for the first half of this. I even shut up for a whole minute in at least 4 different places. I'm getting better. Wink wink.
I want to rant and rave and promote the living daylights out of the 26th annual DSM EVO GTR shootout, but the reality of it is I brought a car, 3 cameras, 2 laptops, a truck full of tools, a campsite and spent time poring over logs while hanging out with friends and fans in person. It was nice to be able to produce content while simultaneously vacationing. I can't think of a better place I'd ever get a chance to do that? My help were volunteers and it was everything we could do to ensure the meat of this material got captured and still soak in everything else & have a good time. There were 4 people from 4 states in one state and one person traveling through 3 states who were working on my tune during the shootout. If that sounds complicated, it was, but a blast was still had by all. If I didn't have those volunteers helping out, there's no way I would even have half the footage that I do. Thank you Chad! You're always welcome on my pit crew!
Tom Tharpe took a time out from all the live-streaming and all the hoards of screaming fans to interrupt me in the pits of my tuning hell. He was driving a tiny powerful 5-valve turbo 3 cylinder car that he drove to the shootout. He let me drive the Dangan ZZ and his whole journey in it is documented. I got to make a cameo driving it. I needed that break! It is well documented in both my logs and my timeslips-that was the moment the Hyundai's luck began to change. Thank you Tom! You got to make a shootout video about something fun! Lesson learned for me!
Watch the whole video here: • The Micro Mitsu Road T...
The fans, the food, the festivities, the fireworks, the fun, it's all amazing. It's sensory overload! I can't wear a body cam, someone would be in jail. We all worked hard to get 6 runs, 6 logs and include the shootout into this topic. The animations were exhausting, but this is an inside look at what my tuning process took from point A to point B after installing water methanol injection. Explained. Of course completing this topic required additional efforts beyond the shootout, and all of that footage and data is included.
The material is pretty thick. Especially if you are unfamiliar with ECMlink, but I do my best to explain it all. With examples. 9 runs of cause & effect. Some of them are pretty bad, but I make up for it. If you use Speed Density to tune some other boosted thing with water methanol injection, the principles here are all the same because your fuel is still calculated by pressure and RPMs, so you have a VE table similar to this on whatever it is you have. This covers in EXTREME detail how I adapted my ECU to work together-yet independently from the water methanol kit because of its failsafe and some creative wiring. If you want to know more about water methanol injection that made this possible, please watch my installation video and read the description. If you'd rather read this description, well okay then... keep going...
Water/Methanol is a fuel charge that becomes part of your AFR's. It makes you rich. You have to lean out your gasoline mixture when you use a water methanol kit for two reasons. 1) because water vapor displaces some of the air, making your normal tune slightly rich, AND 2) methanol is fuel, making you slightly richer-er. The non-combustible nature of water slows the burn as it converts to steam, raising your final compression and your octane rating. Intake temperatures are spectacular so the air you DO ingest is very dense. And cold. If you can lean out your fuel mixture correctly, just on the verge of knocking... there is a lot of power to be found. You'll find that knock threshold has been moved. You'll find you can get away with just a little bit more. But If you don't take any fuel out, there is literally no benefit to installing water methanol injection. It will actually slow you down.
YES! I made a lot of mistakes along the way. Sometimes that's how you find problems. I got help. Plus I'm going to show you my mistakes, examine other approaches and ultimately demonstrate what works best. I understand the OpenLoopMaxOctane table a whole lot better today. That's why I waited until now to explain it.
No seriously... there were multiple reasons why it took this long to comb through 987.7 GB of footage to only use 771.67 GB of it to bring you a video that's less than an hour. But by the middle of the video you're watching results happen from getting it right. I didn't break records at the shootout other than a faster pass than I ran at last year's shootout... but I did break some all-time records and they're here in this video, too! - ยานยนต์และพาหนะ

Thank you for the video chock full of so much great stuff! Thank you for the kind shoutout, I enjoyed The Shootout retrospective and it was so great hanging out with you and going for a ride in the Dangan ZZ! Happy New Year Jafro!
That was a memory of a lifetime! The shootout has never disappointed. The hanging out part is just as fun as racing! Thank you for showing up and changing my luck! Someday I'm going to need to leave the car at home and spectate again. Happy New Year to you as well!
jafromobile: *new video exists*
Me: smash that nutt button
Seems like you've located a new button o.0
I hope you got around to watching the video, it's a good one.
jafro and project binky. what a day.
They've been very productive lately! I am rather proud of the 10 videos and 5.356666666666667 hours of footage I produced in 2018 as well. It's a great day for TV if you're a gearhead.
Happy 75th birthday (21:40) to JafroMom!
I made it 500 miles home to VA in time. That was Me, Mo & Bro. One of the reasons I never made the shootout until 23rd annual is because it always falls on my mom's birthday. Always. So does back-to-school and I work in higher ed. It's always a miracle when I can make this event.
This is gold in video format, thank you so much for doing all these. Happy New Year, and may this one bring a lot of fun projects and rewards!!!
I love how long and in depth all your videos are!
Hooray! Another jafro vid. Cause of you I'm porting and polishing my Miata head...I'm like 15 hours deep man, thanks for the vids!
Your videos are so entertaining and informative to watch !!!
Good luck in all that comes your way in the future. I hope it goes well for you.
Merry Christmas and Happy New Year Jafro!
Thanks for creating this, nice to hear the details, so rare online.
I’ve been fiddling with my water/meth for years and this makes me feel like I’m not alone!
the kill on the mustang cracked me up
You know he's mumbling under his breath turning around from the runoff lanes while reading my license plate and how all 4 doors are still attached.
@@Jafromobile HAHAHA jaws on the floor finding that the hyundai gapped him... gunna have to explain to his girl why he bought a mustang now...
at least no crowds where harmed😁
Yess!! I thought the same thing haha! He never even saw it coming when he lined up next to that 4 door family car lol.
I'm 70 years old. Been straight line racing from age 16. Never in my life have I spun a 'front' wheel. LOL.
I get it. :) All of my other cars are AWD, this FWD thing is a personal challenge for me that I wanted to take because AWD launches are like cheating.
Also! My thanks to the chef of this amazing video. Thanks for going through the trouble of filming, writing a script, documenting your passes, giving detailed information on what is happening, why it's happening, and how detailed driving in a straight line can be. This is why I love your channel man. Jesus how long did it take you to produce this?!?!?
Gosh i was just talking about you! You are truly awesome 👏 opened up my mind like a can of worms
I think this videos first appeared on my feed back when you first released it. I've had meth injection on my car since 2017.
Just now in 2023 I'm playing with self tuning so this is really great to watch again.
With the level of understanding you have and the amount of time you put into this you deserve to smash all your goals. I'm going to have to watch more of your videos and find out how you did.
Just as I had a base tune (I thought) for my car a wheel speed sensor went out. I think it's the last of the 4 that I haven't yet replaced. I also triggered transmission errors which I'm hoping are simply a result of invalid figures causing out of range results and not hardware. Replacement sensor arrives Monday. Right after my weekend is over. Oh well!
I've been waiting for an upload for ages but considering its 1840 uk time new years eve and I'm almost drunk I'm going to watch this in the morning when I'm hungover stinking of farts. keep up the great content jafro most indepth channel i ever saw. Happy New Year .
Jafro vids are the best! Always a nice surprise to see one pop up 😁
Fastest hour on You Tube!!!! Thanks for sharing. Glad to see you making progress on your tune now all the hardware and electrical issues are sorted. And there is wealth of knowledge at these events. Probably my favorite part of attending.
Have I been awake for a whole hour now? As these electrical issues get sorted, the fog of them lifts, and its real problems only become more clear. It still has issues. If you scrub through my logs, notice how my AFRest value jumps around. There's still noise in there from _something_. Oh what I would do to get a clean log from start to finish. In other news, there's a box on my living room floor with a brand new 1992 Hyundai Elantra speedometer cable in it. Unbelievably I found everything. It must be identical to half of everything with a 4g63 in it or something, because I had no trouble getting it.
@@Jafromobile Might be time to call Painless. Worth every penny IMO for old cars with semi modern electronics. Either way, I know you will not rest until it gets sorted. If you can not trust your sensors, things can go bad quick.
*THANK YOU FOR THE FOOTAGE. HAPPY NEW YEW YEAR JAFRO, LOVE YOU MAN*
HELL YEAH BROTHER! :) b
always a pleasure Jafro. happy new year
All that info is tuning gold! Thank you 🙏
I love the fact that Jafro gets real into the details, not a lot of other channels go into this kind of depth. Also I never watch anything else an hour long and go back several times in the video to listen to stuff I didn't quite catch lol.
I have the same philosophy with raising children. Not that I have any children. But if you don't talk to children like children, they won't behave that way. Nobody baby talked me or spared punishments, I asked questions when I didn't know and they got answered. I believe I developed faster than my peers as a result of that. So through my examples, I learned to make my videos for my equals. I feel like glazing over general descriptions of upgrades is equivalent to talking down to people. I believe wrenching at 1x is tedious and condescending because everyone [even primates] know how wrenches and screwdrivers work. If the videos keep my attention, they'll keep your attention. And as for the material?... if I can do it, you can do it, anyone can do it. Just add positive reenforcement and make sure you're having fun! :)
What a treat, the BOM guys tweet they're releasing Ep21 at 8pm tonight and all of a sudden Jafro appears, my cup overfloweth.
I've already seen it. Sponsorship has its benefits! Spectacular work. You'll see my comment in there. ;)
Uhh, hey guys, so whats BOM? Haha. All I can think of is Bill of Materials.. I'm racking my brain to come up with an acronym.
th-cam.com/video/uOkDhEW9Xss/w-d-xo.html - hmm, I'm guessing not this.. lol
@@donnylao1 It's Bad Obsession Motorsport. Search that, subscribe, and come back in 11 hours when you're done to say "Thank You". ;)
Nice video! And good work on the friend footage, great addition!!
I have a 97 GSX with 67,000 miles Ive had since I was 17.... Im much older now. It sits protected and never driven. Since finding your videos 3 days ago I have purchased a jdm 6 bolt for a swap that ive always wanted to do. Thanks for the motivation!!!!!!
its awesome to see u make some passes with the newest setup,thx for sharing man
I'm really getting a handle on it now. That mph in the 13's, though... Its problems are all in the short end. If I can ever get that right, I will walk through the 12's in this thing. My 3,355 lb GSX ran a 12.21 at 116mph pump gas with these same cams, valve springs and turbo. They're in a car designed for 80 hp at the wheels. It still has problems, and I hope I can fix them all before the torque folds this chassis in half.
Almost in de 12, keep up the good work jaffro, i will keep watching and supporting you.
My camera man left a sandwich in the car. Had I not had that extra weight... ;)
Hey Jafro, good to see you again. That Hyundai is really coming along, glad to see that you finally got that front end figured out on your launches. But anyway, ive seen a couple videos of yours with tuning using DSM link and that is the platform i will be moving into by this spring. Id love to see a couple more videos going into deep explanation of the program and some more quarks of it as well. I love your style of videos and follow your reasoning and explanation very well. Keep it up! Ill be waiting for the next video!
Yaaaay another Jafro video!! That’s crazy I never realized how much fine details go into tuning
That's because nobody ever shows you what they're doing. ;) b
@@Jafromobile Hey Jafro! Love your videos!! Now, quick question, what are 3 things you would say to recommend new guys getting into tuning for the first time? Also, Are Stock OBD-ll ECU tunes or Standalone ECU tunes better to begin with?
Love your work man!
I can really appreciate my meth setup now, I've never actually tried tuning with a progressive controller, rather I use the Ecmlink output and secondary maps, it makes it such a breeze.
Happy New Year from your Canuckastinian brethren and see you next year!
Exactly, quick and easy
I wanted to do a segment on Canadians and Maple Syrup. Don't worry, it wasn't going to be derogatory in ANY way. It's one of the most cherished gifts I've received from a non-family member... and I'm so happy that-other than my mom and the first meal, I don't have to share it with ANYBODY.
Also, I will consult with you when I'm ready to ditch the progressive controller. If I can't explain WHY your method is better from experience, then I've got no business making that video. However, that's a topic that YOU could explore... I'll be happy to consult with you on animating logs if you need it. ;)
Awesome video! Even spotted my colt a few times at 3:54, 39:46, and 52:08. My car did great all weekend besides taking until the 330’ to get the turbo to spool. Thanks for the videos!
Thanks for posting links. I may never make it to a shootout, but at least I can vicariously watch a bit of it.
Aaron, I love that car! I've been shooting video of it every chance I get. I had a camera malfunction at the 23rd shootout that left me with only your burnout, and I was flippin' furious about that when I got home and imported it. I know for a fact that it was your car because of the blue stripe. I look at the tires and you know what they say to me? "Business business business business". I gave my camera man explicit instructions to capture every Colt he could find making a pass because I get SO MANY REQUESTS for my Colt on this channel. People love them! People are like me. You're a natural badass, and you already have the AWD thing I want. ;)
Jafromobile Thanks man! Love watching your colt build, I actually went back and had to reference your driveshaft video when I was redoing mine and getting a custom one made.
Binge watching yet another one of your videos. Can’t wait for the next one brother!! You need to see my Wilwood Big Brake setup...that would fit on multiple cars in your driveway....and can still run 16” wheels.
Your videos about the nitty gritty mechanical and tuning aspects of DSM ownership are the best on TH-cam. The more I watch you trying to tune that thing, the less confidence I have lmao. Mine has been down for years due to... health issues, so maybe I've just been building it up in my head, but those tables and the amount of control looks overwhelming. The LS guys got it easy with their Holley drop on EFI that auto tunes itself lol.
This is impressive for a daily that can carry your family
Thank you Daniel! Finally an objective viewer! I wish Google thought I had more than one thumb.
Great time out there. Very nice meeting you.
I failed this year on schwag. I had schwag last year. I'ma have to work on that! Be sure to remind me at the next one that you didn't get your schwag.
woohoo jafro vid and a video about something i've been thinking about!
This gives me a lot of good info to work from. I'm putting together a mild turbo 4.8 LS setup for my C10 and plan on tuning it myself.
Even if there's no water methanol, the principle is still the same. This is how SD works. ;)
Take a look at Sloppy Mechanics if ye haven't already, helped me a LOT with understanding my tuning.
What turbo are you using?
@@alloyspeed1889 CXRacing 20g ($224 ebay turbo). Seemed appropriate given the rest of the car.
thanks agaim Jaffro for a vid will so much to help me try and better use my water /meth injection,
pls keep hammering that et, youll be there before you know it!
Jafro! Happy New year man
Hey Jafro! It was good to meet you in person and chat for a bit this past Shootout! Hope to see you there again next year man!
I'll be doing everything I can to get there! We'll do it again!
Your editing and humor take the dryness out of the topic. I look forward to more vids and that 12! Keep it up.
Just when I thought Christmas was over!
I've been waiting for another vid.
This makes me appreciate Tunerstudio auto tune feature a lot more.
Hondata has a similar automated feature, one that will sample, recommend adjustments and re-flash a new value in the table for the cells you're using... of course, that's done by the software that connects to it, and (ProTip: the faster the laptop storage you have the faster it will tune your car for you, in other words boot camped MacBook Pro Touch Bar model running windows)... but ECMlink does a great job of making sense of all this. It's laid out very well. Logical.
Yeah I don't like to trust the software to make all the decisions, I tend to use the VE analyze function , saves me from having to dump everything to excel and back , and there's filters so you can exclude cells based on Map,rpm, temp tps, ect. makes tweaks in the staging lanes painless. Can't wait to see this thing hit 12s, it would go 11s on slicks for sure.
@@StovallsGarage I had the smallest slicks you can fit on a 15" wheel and they rub structural and suspension parts. Even with a spacer they didn't fit. If I didn't have to cut into the chassis or install $1,200 coilovers to make them fit, I'd have kept them around.
@@Jafromobile oh yeah, forgot about that.
@@Jafromobile MH does make a 23x 7.5x15 it's what I run on my escort.
I watched all these videos and just now realized your in Richmond! I’m in chesterfield myself!
Another new years eve Jafro video!
I have to. Either I'm shooting it on New Years or I'm releasing it that way. Either way, it's a tradition now. Hopefully this year I can do both!
Yeahhh Jafroo happy new year
Always a pleasure. Thanks.
3:23 HE SAID JOE WRENCHES! JAFRO SAID JOE WRENCHES!! Great watching this Jafro! 57 minutes is a long video, but it had at least 59 minutes worth of info!
We should have done a segment somewhere. I'm sure Ratchets would have been down for it. I wish I were more creative at the time, but it was awesome seeing you at Buschur and the track again!
You nailed it in the video. It's too hard to do both. You either race, or you make content. Doing both is too hard.
Or... Impossible?! Your build is really coming along! It's a big motivator for me to watch that happen. Everyone should be watching! I'm sensing that a lot of people will be happy to read me saying that I know a lot of people are sick and tired of this Hyundai and are ready for me to work on ANYTHING else... I'll be going down your road very soon.
Thanks Jafro, and good luck! This build I've been working on has been a lot more difficult than I anticipated. It's a huge undertaking to start from a bare chassis. If you need someone to bounce ideas off of, I'm available. Hopefully I've learned something from all of this!
Every body guy I know says "never take a car down to bare metal". None of them like to ever do that. It takes balls. It takes a LOT of work to bring them all the way back up. Sadly, I know this is one of the things that I must do in this lifetime, and based off of their reactions, they're making me believe it will be the automotive job that could end my patience for the hobby. It takes a special kind of gear head to love a car that much. The hours... It's just such a commitment to do it. You've learned a ton from this, don't question it.
Yo Jafro, Thanks for helping me diagnose my strange MPI relay issue that caused my car to not make the trip to the shootout this year. I finally got it sorted out (it ended up being a corroded terminal on the MPI fuse in my battery relocation). Long story short, I got the car fixed and got it into the 10's in full street trim (minus an air pressure adjustment).
Thanks again!
You mean I got it right for once!?! SWEET! ;) 10's on street trim is a big accomplishment! Wow!
@@Jafromobile It should have went faster than that, but the stock block leads to conservative timing numbers to keep it alive. 40 PSI on the stock block though... E85 is a wonderful thing :)
Also,
The speedometer cable wont fix the speed sensor issue... it is simply the jank reed switch signal provided to the ecu that comes from the actual gauge cluster. this is just the nature of that sensor. My 1g does the same thing. A 2g sensor won't do that, but it also wont drive the OEM speedometer, as it is cable driven (which you knew). You'd have to either:
A. Live with a non-functioning oem speedometer, odometer, and trip odometer... or
B. Install an aftermarket speedometer that works with the 2g sensor (I believe AutoMeter has these)
@@talontsi92 I suspected that this would be the case. I've always known they were cable driven, but honestly I've never looked closely at the cluster side. Is that sensor just a mechanical switch? Is it a hall effect sensor? How does that interface mechanically? I bought all 3 parts, the cable, the cup and the seal. The parts I'm replacing are between 27-29 years old. I hear a whine in the dash that's always annoyed me. For several years I've suspected that cable may be dry rotted on the inside. I'm also pretty sure the cable seal's shot because I got gear oil on me once from working inside the dash. The smell is unmistakable. But we'll see if the new cable makes any difference? The good news is that it probably needs to be replaced anyway if it's siphoning oil up into my dashboard.
@@Jafromobile A Reed switch is definitely not a hall effect sensor. A reed switch is a physical switch that is magnetically actuated when the magnetic field passes by the contacts. A hall effect sensor varies voltage with changes in a magnetic field with no moving parts.
What I suspect is happening with the reed switch in the cluster is essentially the contact bouncing at speed. I've seen dramatic swings at the top end of the track, as I believe the problem only gets worse with speed.
I simply believe that the type of switch that Mitsubishi/Hyundai used was "good enough" for the OEM functionality of the car, but was never intended to be as accurate as we want things to be.
HAHA I LOVE IT. I am sure I'll be going through headaches something like this soon enough... but maybe I'll give e85 a try instead ;-)
Also, wow you walked that mustang X-D
One of the best pieces of footage I've ever captured with a GoPro. Scott didn't do to shabby at the trackside that day, either. I'm proud of everyone willing to take a shot operating the "big camera". Chad did a great job for a first-timer, too! Everyone should be proud!
I do hope it was atleast a gt350, mustve been a big "wow" seeing "that little red... What? A hayunday?" do so well 😁
He had a sticker on the bottom right side of the rear bumper that said "Bullitt Edition". It's not forest green. Where's the shaker hood? Where's the V8? I have a real problem with what Ford has always done with their iconic and legendary halo cars. For instance, the Cobra edition Ford Mustang. The "Cobra II" While it's a cool light car to build a drag car out of today, it was a horrible representation of something else great that had to do with the brand. A Post-OPEC stab at the consumer with a performance-less sticker package. I have the same issue with them replacing V8s with 4 and 6 cylinder engines and giving them a throwback name that evokes a completely different emotion. I feel like it shows a lack of ideas. Cars aren't appliances. Even if you can make that 4 or 6 cylinder turbo faster than the original car... if I see "Bullitt Edition", I want the loud angry forest green V8 mustang fastback running from cops sideways getting airborne in San Francisco. Maybe it's just me?...
@@Jafromobile thats definetivelydefinetively what springs to mind, yes. Same goes for those new "sixpack" cars...
Altough, im kind of torn on the appliance bit. I know for certaintycertainty that they ARE appliances. Designed to do work for us, and replace the common horse. But still, i think all cars have a soul. You get attached to it. Its personality, its quirks, its flaws. And that speaks for them not being that.
But hey, atleast they still do produce v8s, give it a few years, and we wont have that even. Give a few more years, and our beloved turbo 4s are in danger 😭
@@maxpower700 No matter how much of a Frank Zappa fan I am, I have never been able to fall in love with an appliance. I have been able to do this with dozens of cars, though. I have never fallen in love with a washing machine, or a toaster, or even a magical pig with marital aides stuck all over it, and I am not a believer in the Church of Appliantology no matter what the Central Scrutinizer says. Hitting the spin cycle does nothing for me like roasting the tires on something that makes awesome turbo noises with a twitch of my ankle and at my beck and call. I think that manufacturers believing that people want to drive appliances rather than making automobiles an extension of the driver is why modern cars have devolved into things lack everything resembling style and performance. If the car doesn't inspire specific emotion... an emotion that can't be satisfied with any other kind of appliance... then it lacks everything that justifies its existence in the first place. Remember that the American Automobile manufacturers are what saved the USA from the Great Depression because of the car culture that sprang from it. I don't recall any other appliance being credited with creating a culture. So if you're right, and if the modern car is an appliance, we're full circle in agreement of what killed off the American car culture. There were a lot of ugly stages along the way that helped... sure... like restrictor plate racing of the same chassis by 4 manufacturers around a track using things that don't resemble anything any of the car manufacturers are building. No more race it on Sunday, buy it on Monday. I feel like the more we view automobiles as appliances, the more we disconnect ourselves from the emotion of driving them and begin looking for any other kind of reward or pleasure center to take its place. Of course, looking out my truck's window down into the road rats around me in rush hour, I'm convinced we're both correct because everyone's driving down the road looking in their cell phone. By everyone, I mean 95% of everyone around me. Nobody's emotionally connected to their cars anymore. To me, this is disturbing. It's complacency. I hate complacency, normalcy, and especially boring cars.
I’m lost in tables. No better off than last time. I clearly need more time to figure this mess out. Hope you have it because I am not the source for that. You’ll get it because you clearly want to. I am not as much into the drags as much as I am the rally cars, but I still like the drags. Been doing that since the muscle car days. The tuner craze has been around longer than most people think. Tuning small motors like VWs have gone on since the sixties! That I do know! You keep pushing and you’ll figure it out! 👍🏻👏😁
Even on the VW's, it's all about volumetric efficiency. How much fuel, how much air. An engine's volumetric efficiency changes based on how well it moves air at different RPM ranges. This is just a scale from minimum to maximum efficiency spread out over a table that's graduated by RPMs and air pressure. The numbers in each cell are percentages of volumetric efficiency. The sample cell is where the engine is operating. It's at x pressure at y RPMs... so it's ?% of VE (...so it needs _this_ much fuel.). The fuel being delivered is done so by another calculation and turned into injector duty cycles. If you're lean, you need to add a little bit of volumetric efficiency (air) and it will calculate and add that much fuel accordingly. You're absolutely right, the tuner craze actually started in Nevada in 1945, but the VW guys have been dominating the field very quietly all along. Even carbureted, the goal is to get that air fuel mixture just perfect for your operating conditions. That's actually harder to do mechanically than it is with this fancy graph that lets me tweak every single engine operating condition possible without having to make any mechanical adjustments at all. This is a lot easier than changing carburetor jets.
How I wish they day would come when everyone everywhere used bar to describe pressure.
It's so damn easy. 1 bar, approximately one atmosphere.
I will never understand psi because it is a stupid arbitrary number (just like most other non metrical units).
Thanks for the vid! It was a great watch.
Totally agree, It's a much simpler volumetric measurement when you know the size of the container. Ratios being about chemistry and all...
@@Jafromobile calculations just becomes so much easier.
I saw some 1320 video about some guy who pushed 112 psi through a 4g63. As usual I had to Google how much that was and turned out to be 7.7 bar of boost. That's insane. 7.7 times the atmospheric pressure, I.e 7.7 times the natural volume of the engine. 112 told me nothing related to real life.
Happy new year jaffro. Have a great 2019!
Oh man, 2 months of withdrawal symptoms finally abated.
Don't overdo it. This stuff's really pure.
@@Jafromobile quite addictive too, watching at 2:30 AM who needs sleep anyway lol
I'm sitting here, 45 hours drive from home, watching one of my favorite automotive electrical diagnosticians. You want to make a vacation to Tahoe to help fix my Jeep?
Thanks for another great video Jafro. Love the mustang kill!
I've been to Tahoe! Weirdest beach I've ever seen. The grains of sand are simply enormous. Like big round smooth rocks or something? I hugged a bear! If you're in Tahoe, I guess that means you're buried under like 10 feet of snow right now?
If you have the option to TuneIn flat foot shifting, I highly recommend it. I use it on my WRX and I never lose boost. Yes it's a lot of trauma on the clutch but then again drag racing in general puts a lot of stress on the drivetrain. I have my RPM set to 4500 on my car for flat foot. I love watching your videos, I hope you continue to make them. 🖖
an upload from BOM, and Jafro? Is it my birthday & Christmas?
Excellent
When i first watched this video, very little of the ECU tuning made sense. Now I've got my own ECU and Water/Methanol injection kit. Everything you are saying now makes sense. Yes, the AEM tuning guide is confusing. Very glad I rewatched this video.
Okay, I am just getting started. I did a run without removing much fuel at all. I originally had 11/1 AFR with no water methanol. Now it is dropping to 10/1. So I need to remove fuel to get back to 11/1, which is my target AFR?
It's gonna be a great year.
...because I'm finally all out of Hyundai material to produce? ;) Right? I mean... has everyone seen enough of this car until I've got a 12 to show you? Be honest. But yes, it's going to be a GREAT year!
@@Jafromobile Out of Hyundai material? How dare you sir :p a 12 is the minimum viable end to the Hyundai saga and I think it is safe to say we would all like to see more of it than just that.
@@elliotcurry2284 It's going to get its 12's, and I'm definitely not getting rid of it. I'm just not sure if the massive drop-off in views my channel is receiving has to do with TH-cam or the material? I think it's the former, but it's a viable question. I know that interest in drag racing is at an all time high (thank you NFL, thank you Street Outlaws [and also thank you Trevor Holland]), but people aren't watching as much Jafromobile as they used to. I used to get 20,000 views overnight with a new upload. Now I get 4,000. We'll see what a difference a change in subject material makes? I do have 4 other cars after all. I've been working on the ugly kid so long, it might take a few videos to regain the spotlight, but good things are afoot for 2019, and you'd better believe this drag racing season opens with a Hyundai 12.
I dont wanna be a "drag" but I feel getting some tires with low psi should grip much better. Dont take my word for it tho it just seems to be the trend after turbo. You are so good at explaining this stuff man. Seriously, good job.
hi jafro love your videos. i had a question about ur speed on your log been all choppy have u ever found out what was going on my car does the same thing thx. keep up the good work with the amazing videos ;)
I'm still looking for it. I've squashed so many other bugs trying to chase it down. It's the one thing holding me back. It used to seem to follow the Baro signal, but I fixed everything related to that circuit until I got a clean baro signal and it's still doing it. Infuriating, I know. I keep hoping that whatever component that's causing it eventually breaks the rest of the way and gets replaced. I've been through the harness 3 different times now.
@@Jafromobile ha ha i know how u feel me to i tried everything if i find a solution i will let you know thank you anyways hope u figure it out
the black dsm with the chute gets me ...........
Damn boi i missed you!!!!!!
Awwww... I missed you, too! ;)
I didn't know you were here in Norwalk Ohio last year. Are you coming back this year I'd love to meet you and race ya 😁
Thanks for this, the instruction on tuning this sounded confusing and tuning a point leaner freaks me out if it fails.
good job on the video. im learning more about ecmlink. my wrenching is good but tuning is on another level lol..my 2g gsx on ecmlink v3 is still running pig rich. idle afr is 14.7 but its still killing my spark plugs :( got ways to go but thanks for putting up these videos
If your global fuel is correct, and you're set up for Speed Density, then you can use the exact techniques shown in this video to fix it. All the "extra" you need is a wideband o2. Turn off everything but AFRest, your Wideband, and your throttle position. Where you're at 100% throttle, tune the cells you're using until you've got the AFRest and your wideband signal sharing the same space. If your global fuel setting is NOT correct, work on that first based off of the instructions on ECMlink's website. You'll get it. I have nothing but confidence in you.
JEFF! Can i recommend aerodynamics? Thanks for your videos! Youre the best.
Down the CFD rabbit hole we go!
😅 makes me miss my 6 bolt talon , i used your vids bacl jn the day to learn how to ditch the balance shaft in it
Hey Jafro, are you using a lsd in the transmission? It might help with traction.
34:15 I had no idea what a huge difference NLTS made in boost pressure. Damn.
This is why the data matters! ;) I can read someone talking about it all day long in a forum, and still not digest it until I've seen the data myself. This is why I like showing this kind of cause & effect stuff in my videos. It's the whole "a picture is worth a thousand words", but at 29.97fps, that's 29,970 words per second. There was a time when I felt lost with ECMlink because I didn't know what or why to look at things. Hopefully these examples of it being used help close that gap for all the people who don't have someone to ask... and for those who get it, they demonstrate practical examples of features it provides. Thanks man! How's the new ride?
Respect.
During your no lift shifts are you running spark cut or fuel cut ??
What kind of part could be used that i might or might not have? And what kind of advice on linking the ecu in my 2000 eclipse gst conversion ,what cable should i buy id rather learn to tune my own car after watching every video u posted on tuning about 50 time im inspired that it isnt that hard
It's really not that hard. It's just a series of creative problem solving decisions. It's not so scary once you've seen the inside of it. Most of the puzzles I've assembled in my lifetime had more pieces than an engine. I am completely un-familiar with the 3g Eclipse platform. I've never driven one. I've driven a 1g, 2g, and a 4g (I got to drive that one down PCH 1 from SF to San Simeon), but other than the factory 10-point bolts on the OE clutch assembly that most people blast off with an air chisel and replace with normal bolts, I'm unaware of its inner workings and systems. I know the 2.4L is the only one with any real performance potential, and Mitsubishi kept it around in the 4g production as a powertrain option. Without seeing it, it would be hard to guess?
Lol at the mustang! Nice job.
When you rollin up with 1229!
I just got some leather products that eat mold. Just arrived today. Big Red is too cumbersome for parking decks, so the Galant is a 2019 mission for me. I am going to rebuild its AWS, front-to-back. Not disable it. I want it working. If I have a productive spring, I may even look into getting it painted.
21:48 THERE'S TWO??????
LOL! Shoot, I leaked a picture of the prototype!
35-50hp wet shot of nitrous would make that turbo almost instantly spool
I'm already topping off 2 fuel tanks. Might as well make it three! :)
This is fascinating. I'll stand quietly in the corner around all you people and act like I'm just as smart. The plan is to never speak so not to cast any doubt.
Hahah! If you're new here, you started with some really tough material. This car was meant to push stock parts to the limit and clearly I didnt hit it. If you enjoyed what you saw and started with the older stuff, everything will make perfect sense eventually. Stick around because I've got different material coming. Something that isn't made out of stock and used parts. It's a little more fun to look at.
I'm feeling the same...thats why I don't write comments:)
I have stock rods and pistons ill give you if you can guide me in tuning just a little pls and a few things with the evo 8 cam reluctor swap on kia head
Another year not making it to the Shootout sadly. That'll be...7 years trying. One of these years. Hopefully before the whole event is open to any make/model.
Great Video. Do yourself a favor though. If you've got the newer style AEM pump switch to spraying straight methanol. It makes a world of difference in knock and power and is much easier to tune afr's. I ran a 50/50 mix for a year and afr's were always inconsistent from day to day no matter how I adjusted them. I ended up ditching the progressive controller as well and have a relay wired to the fps and I set a few parameters in ecmlink to tell it when to activate the pump. I also started using the secondary maps to adjust my fuel and timing when the methanol is spraying. So far its been the best and most consistent method I've tried.
This is exactly what Jason Drew keeps telling me to do. I know that he's right. I'll probably get there soon enough. :)
You won't regret it I promise! I will warn you though if you have the older 150psi pump I can tell you from experience that the seals are not compatible with straight methanol and will eventually start to leak. From what I've read the newer 200psi pumps can handle straight methanol though.
Cable whip in the speedo cable?
27:59 That kinda sounds like my exhaust did before my turbo died. I sent it off to Justin for a rebuild and after one look at it he asked "Any chance you have excessive backpressure issues?" I deleted the CAT after that and it sounds way better. Anyway, I think you might have some backpressure issues, especially with a 2.5" exhaust like you mentioned. Try a temporary open dump pipe and see how she does ; )
I'm 100% sure I have back pressure issues. You don't hear my car unless the wastegate is opened [dumped o2]. I want to maintain my ability to pass state inspection, so I'm considering a cutout.

MAKE THE NOOIISE! *beep*
OK, I can quit now.
You are the gift that keeps on giving!
Jafro recirculating that bov will help your make more boost between shifts. I know you can tune it to run uncirculated but your losing the surge that can rapidly respool your compressor wheel.
Lets give this man a borg warner efi
What Octane fuel were you running?
Top
Man, I'm no good with computers, if all that is what it takes for my dumb self to boost my car, I'm screwed lol
you are genius
1:35 Hey, I have that shirt! ...except, mine is a more worrisome brown color. That way, I can remain color-coordinated during those "brown trousers" times.
Just curious why the need for such rich AFR's? Your timing isn't even excessive
Average 1g DSM is 7.8:1 static compression, mine's 9.875:1. 2 full points higher of a cr.
How come my nlts isn't working? Clutch switch always says 1 and it's wired like they show how to. Thanks
Unless you have "clutch cut enable" turned on, you won't see a clutch signal. It will stay flatlined. Normally the ECU doesn't even care about this value. It's when you have it turned on that it starts logging it. If all that's on correctly and it still doesn't work, look for a video somewhere in my collection labeled "Clutch wire work-around". I had a blown diode in the clutch wire on my 2g, and running the non-signal wire to ground accomplishes the same basic thing, it just may interfere with your cruise control is all. Meaning that you push in the clutch and cruise doesn't disengage.
Water injection amounts:
The studies done in ww2 suggest that an increase in water-fuel ratio from 20% to 40% provided twice the increase in effective octane rating as did the increase from 0% to 20%. Can that single injector flow that much?
Personally I'll be running a pre turbo boost pressurised system on my 4.0L, and I'll be injecting around a litre a minute onto the compressor nut.
Wow is that difficult to tune for? I'd imagine some is going to cling to the intercooler
@@littlerhino2006 In a word: Yes
In many words:
Yes, the boost compensating part is automatic, flow will be proportional to boost (well, the square root of boost) which is close enough to the "extra octane" requirements, but rpm requirements are a different story.
Making it proportional to rpm is going to be difficult. Because my engine will be on full boost from 2000rpm to 5500rpm there's about a 275% difference in flow requirement at the same boost level. I'll need to incorporate some kind of rpm control to stop it from flooding at the low end. With water injection volume the tuning window is quite wide, so a stepped system is ok, but I'll still need to have three or four "stages".
No intercooler. With this volume of water I won't need one for temperature control, and as you pointed out, I'll have pooling problems if I even try
Yeah, but are you going to drive that car on the street, though? I like your approach. It's one I've considered on other projects. My efforts are to prevent melting pistons in the event that my water methanol tank decides to run out before my gas tank and still get me home. When Nick Stack had a compound turbo setup, he was spraying methanol directly into the turbine housing, but had a bung welded onto the compressor housing for a solenoid. It was a brilliant setup because of how it solved compressor housing temperatures, but far beyond my math skills to fully explain or repeat. I'm not running 7's [yet]. Who am I kidding? I'll probably never run 7's.
@@Jafromobile No its not going to be on the street, but even with the engine like this I could. It's a relatively light car for the engine size (1450kg for a 4 litre engine) and is tuned for bulk low rpm torque out as standard, it doesn't need boost at all to be quick. It also has low enough compression that other people run 5-7psi without any intercooling at all on premium fuel. So if I was willing to spring for a real ecu I could easily tune it to be safe without water.
I just realised I could use an rpm mappable boost controller to do the rpm function easily...
man, and i thought running 20 psi in my tires was low. I'll have to run 15 the next time I can get out to orlando.
FYI: it was 48°F. In hotter weather, 20 PSI doesn't sound bad. You want to base your tire pressure off of the surface temperatures. I can't tell you the rules about that because I can't find anyone willing to share them.
Do you data log your fuel trim levels?
What... you mean like injector duty cycles? AFR's? STFT, LTFT values etc...? If so, then yes. They should all be displayed in the logs.
Ass much as i hate 4 cylinder cars. The wife just had me pick up an AWD Eagle talon.... Here we go Jefro. Its what the wife wanted. Now i have to rewatch all your stuff to get a handle on these cars. I spent the last 10 years on Ford Modular motors. 95 Eagle Talon, 97 Grand marquis, 93 Ford Crown Vic(500k Mile car) O3 marauder, 00-01 B5 VW Passats.
One question.. Why is the engine the wrong way? im confused /s
Where r u located??
