Hey I just wanted to stop by and say, your total engine pull, rebuild and install videos inspired me to do my own long block swap in my 08OBXT that started knocking shortly after I bought it. Looking forward to more videos!
I've been using rom raider to log afr, afr correction, afr learned, rpm, throttle actuator position, and MAF volts. Then using mega log viewers histogram with afr correction + afr learned calculation.. Histogram is rpm, maf volts, and the calculation. Worked amazing on my 06 2.5i with 63mm wrx cai. (Yes an NA/T EJ253 AVLS.) Wot logs I do exactly the same way you did it. 24mpg on e85 and I have boost, not too bad for these near $5gal days.
@@SWSpeedCo That 10:1 compression, high cruise timing, and VVL putting in work. Admittedly I can't push crazy power out of this build, but it's about as fast as a stock wrx, thats all I need from a winter daily.
mennn u have safe my tunning life car , this guy is very Good at what he is doing very explanatory good knowledge about Subaru cars , keep up the good work. and with this tunning video guide you deserve a lots of credit 💪😍
Good video. I used a program I found online that does maf scaling. Ran the excel macros a few times and my car runs decent. I copied ignition and some fueling tables from Cobb OTS. I only get 16 mpg now but my car feels fine 🤷🏽♂️🤷🏽♂️🤣
Super helpful video! I of course did the stupid thing and upgraded BOTH my injectors to ID1050s and a COBB SF intake and box at the same time and threw away/sold the ORM stuff. 😢 Great…how screwed am l, lol!! Well, at least my car starts albeit ugly, lol!
I think injector dynamics have good characterization so I would just set the injector scaling and latencies to the manufacturer spec and then adjust the maf scaling to get it dialed in
Always find great content in your videos. After almost 4 months of work, my ej20x is almost ready to go back in the car. My Tactrix 2.0 is on the way. I'm paying for an e-Tune, but ideally I'd like learn how to tune myself. But I didn't order the two green test connectors, where do they hook up to? Thanks for the Tuning guide link btw
Glad you are figuring it out. The green test connectors are already on the car. You just need to pull the carpet on the passenger side back a little to find them. Then when you need to write or read a rom file you plug them together and unplug them when your done
Thanks, im glad you found it useful! I use romraider for data logging, ecu flash for editing and flashing, and megalog viewer for looking at the data logs
So, I guess I should have done more research before buying my car. I thought it was just "slightly modified", but it turns out it has (AEM CAI, Grimmspeed EBC, Down Pipe, Aftermarket Intercooler and the AVCS to Turbo routed oil line. And of course, most likely a tune (because it's averaging only 13.5mpg city driving). I'm a novice with these turbo motors/tunes.. Can you tell? lol My problem really is my car did not come with the Cobb AP and I have no idea what tune it has. The previous owner was a mechanic who just maintained it, changing the fluids, brakes, struts, etc., but he didn't touch the "performance parts". He kept the car as he bought it with those mods.. What do you think I should do in order to find out what tune it has? Can I buy a used Cobb AP or do you think it has one married to it? Sighss.. Had I known this, I'd have probably waited on buying the car.. I'm now trying to contact the person who owned it before the mechanic to see what I can find out.. somebody suggested buying a Cobb and rewrite the ECU.. Looks like I’m going to have to do lots of research on tuning.. If you have any tips, they would be greatly appreciated.
So If I had to guess I would say that chances are it has a open-source reflash tune through romraider. The reason I make that assumption is because it doesn't sound like there are any cobb parts on the car so at no point would an off the shelf cob tune work on that car because of the mix match of parts. And I doubt someone would buy an accessport just to get a pro tune because that would cost around 2 grand all in all. Sounds like it has what would be classified as a stage 2 tune. Idk if your trying to put it back to stock or if your just curious, but if you want to see if you can pull a rom file of the ecu, the cheapest way to do that would be to buy a tactrix open-source 2 cable, and download the ecuflash software. If you can read a tune of the ecu then it is an open-source tune.
I have tgv deletes so I connected the analog wires from the wideband sensor to the old tgv connectors to log it to my computer. I believe I also changed some code in the definition files so the formula was correct for the wideband
Hi mate How did you do CL scaling town driving or highway? And what are you been using to do WOT scaling just a RR log data and wbo2 or some different programs ?
To do cl cruise tuning I am using the maf tuning table in RR logger. For WOT tuning I use a wbo2 sensor and log final fueling base, and maf V in romraider, then I view the data in mega log viewer software to find the error and adjust maf scaling accordingly
So when I use the maf tuning table I do free way driving varying speed between 65 and 80 to try and cover as much of the maf v range as I can. This is because you don't want to move the pedal rapidly so on the freeway you can keep the pedal pretty consistent so the maf voltage isn't jumping around.
I've been experimenting with a new way of tuning maf scaling which is a little easier imo. I disable CL fueling so the car runs open loop and I drive around town logging maf v final fueling base and wbo2 sensor and then I can put this into a scater plot of mav v vs afr error and filter out off throttle data when the injectors shut off and then use the scaler plot to change maf sensor scaling. It sounds complicated but it's alot less finicky than the maf tuning table
6th gear and gentle on gas pedal. I get that Hpa course as advice me long time ago and I was trying to do what Andre with Mega log viewer but that's not working for me lol
You should only need to adjust the WOT range of the maf scaling for a bigger turbo as long as the plumbing in front of it remains the same. With a bigger turbo you will be hitting higher load ranges that you haven't hit before so they will need to be calibrated
The maf scaling tab is where you can adjust values to get the AFR under WOT correct, but for timing and fueling you will have to re scale the load ranges
So I use romraider for data logging only, and I use ecu flash to do all of my adjustments since you need to flash the ecu with ecuflash anyway, might as well edit with it too. If your new to tuning I would recommend hpa academy, that's how I learned to tune, they go way more in depth that I did.
Yeah I'm starting to learn. A lot of ppl on yt recomend hpa academy are they worth that money?? And I was doing all data logging with RR too but you can do adjustments in RRecu as well.
You can do editing in romraider, but you still have to use ecuflash to update the ecu with the changes you made, its more time efficient to just edit in ecuflash because then you don't have to save and reopen the file in a different app to flash it. Plus ecuflash has a better interface in my opinion. Hpa is definitely worth the money. If you think of it this way I spent like 400-600 on classes and a good tune is going to cost $1000. I've already tuned my car like 5 times and now I know how to tune and can do it myself for the rest of my life. The knowledge is always worth it
I haven't heard of that one but a specific course to your car is really helpful when you are learning how to tune. Its also beneficial to have a broader understanding of tuning in general if you plan on doing different cars in the future. Hpa also has a good amount of subaru specific examples as well.
Any advice for getting a safety tune on an 05 LGT MT? I found a map on ROM Raiders forum but I'm waiting on the OpenPort to come in and I'm super nervous I'll screw it up
Ok, yeah I've never used a tune someone else made but if you find one that dies what you want and there are other people that have had success with it it should be fine
Yeah so just make sure you download the rom file on your ecu and make sure it's viewable in romraider. Save it in a safe spot and make sure it's labeled stock tune. Then you can flash the new tune on.
@@SWSpeedCo no it’s 2.5 n/a motor. my forester is setup for overlanding and I wanted to free up the exhaust so I’m planning on doing the same custom exhaust setup like yours along with an uel headers because I love the rumble sound.
Hi can you do another video for mitsubishi car evo or lancer, th-cam.com/video/vCSyQIOXUOk/w-d-xo.html this part is a bit blurry, bit confuse how to identify long and short term correction, and how to know if its lean since the ideal range is 1-5 as what you said.
On the setup in the video I was making 265 whp on 91 and 320 whp on e85. Currently on the new setup I made 380whp on 91 and I think I was making about 420 whp on e85 before I blew 3rd gear lol.
@@SWSpeedCo damn that's actually very impressive I really like how it's turning out 💪 off topic question because I'm curious if you ever had the classic problem where between 2-3k rpm the car momentarily stutters and then after 3k it goes smoothly. I have a 2.0 non turbo and the only thing that helps for some time is to do ECU reset. Have you got any idea what it could possibly be? Thanks.
I had that issue before, it is a mechanical flaw with the fuel system design, there is a engine load compensation table that subaru uses to band aid the problem. Idk why it would get better when you reset the ecu though
@@SWSpeedCo Ahh right I get it now thanks appreciate the help, I've been stuck trying to figure out what the issue is for a long time and couldn't find on the internet. what is the easiest way to fix this?dealership or some guy who knows his stuff and can sort it out?
You can try taking it to the dealer but chances are they are just gonna tell you it's normal, the only way to fix it is to install a aftermarket fuel rail setup, or you could try and find someone who can tune the table I mentioned. Unless you modified something fuel system related I wouldn't touch it though. The problem might be something else that is just exaggerating the problem more
