Thanks for sharing. What I like most of all is the honesty in your videos... you keep it REAL.
Thanks for all you do. Loaded one of your basic tunes to start a n/a 5.3 in a 86 chevy c10. Works like a champ! Was good enough to get me up and running to start tuning it myself!
Ftw love hearing this
You are the best. Flet talk. Helps and share all you got is so damn nice of you. Thats why you are rewards with all kinds of things. God Bless you and family.
Man, this is some top
Shelf production value stuff. Nice
Thanks Matt,for all the work and time you put in for us meatheads.Couldnt figure out half of this stuff without your help.Thanks again
This explanation is way, way, way more concise than when you were just telling us about it a couple months back. I can't express how much I like the studio format for this kind of thing. Excellent work!
Lower base pressure will help the large injectors like the Bosch 210's achieve better idle quality, and will not be so rich when you are limited by your fuel table resolution.
Wow that dual table setup is sweet. Hope to see that working and up on the sloppy page!
Appreciate the clarity, thanks Matt!
I look forward to the efilive flashed file testing. That and the intake manifold swap to the tbss/gen4.
Ive had this P59 custom OS for a while now and I was so confused because mine was different than everyone else's. I didn't realize I had such a one-off thing. I've posted on some Facebook pages and people say "how did you get your VE like that??" and other stuff. Btw, it works great on my setup! 2006 Sierra 5.3 w/ s475
The dual ve?
Yes the dual VE and the Boost vs. KPA; you are able to pull timing via MAP which is a cool feature. My tune isn't scaled so I run right off my timing table at 1.20+ g/s. I had someone with EFI Live do a base tune back before I had HP Tuners.
@@SloppyMechanics do you have a copy of the dual ve os or you know were i can find one?
Priceless info for my 01. Thanks a ton!
Wait, if all the MAP sensors go from 0 to 5 volts (0 being full vacuum and 5 being sensor's max boost rating), you might be able to use a 1 bar sensor and tell the ECU to read it as a 3 bar, and just keep in mind that the KPA numbers on the table are false. That could get you the extra resolution of the 3 bar map.
The custom efi live os also has boost spark table.
yep boost spark and a weird PE BE system
Thanks for this info Moat. I am surprised to see the newer P59 have less resolution. I always assumed the newer the PCM the more memory and the higher resolution you had. Pretty interesting.
Jess Neal more memory but uses more for dbw program
That makes sense. Thanks for the info ;)
Damnit! There goes my views! LOL. Good video brother! 👍 That lower resolution is why I recommend just using a 2 bar if you dont plan on going above 14psi on a P59. That way you get a tiny bit more resolution. Of course if you wanna go above that and still want that flex fuel then you really dont have much choice. That custom OS with the boost VE is something id like to play around with as well. Any links on that?
All in the tune cabinet!
Thanks brother. I guess Im gonna have to head back over there. Probably saw it and didnt realize what it was. ;)
First off, great stuff and info you present, thank you. After watching this vid and the 30 min one, I want to echo back what I heard on playing with OS and how to "get them" and use them. I have a P01 on 2002 5.3 I swapped and have HPTuners license to all 2002 Silverado engines. From their tune repository I downloaded a 2002 Tahoe stock tune which has Flex ENABLED. So the process to start/get a FLEX tune is to purchase a license for that Tahoe tune file, do the compare/difference from my tune to that Tahoe tune file. Then I flash that Tahoe tune to my P01 and I would be running the FLEX OS with my configuration tune. Doing that would keep my VIN as is but have the FLEX OS feature on my ECU. Further, I can enable MAF Enhanced RTT os mod on that file (I am MAF based only for now, if not forever on this rig) and enable that as well. Is that a correct echo back on what you have said? I have watched both videos a number of times now and it makes better sense each time and adds some more questions - which is good. GREAT stuff you have and great presentation.
Okay I did license the tahoe and updated it with my current silverado tune I have created over time. I wrote that to my spare P01 ECU and I learned that writing ENTIRE write the tune's VIN as well. Thus my ECU has become a Tahoe ECU. Didn't know that. Learn things at every turn.
matt do you have that silverado MAF base/stock tune with FLEX still? I could not find it at HPTuners (2002)
As for the Efilive COS3 with hptuners I'm using 3.6.26 and I have it running pretty good I've got about 500 miles on it so far
With a basic voltage divider you might be able to use a full 3 bar map on a naturally asperated engine. You'd just have to keep in mind that you're tuning on a purposely created false reading sent to the computer. Actually no, I think you'd need to multiply voltage, and a divider would only let you get a chunky, low resolution 1 bar map to work with boost... oh well.
interesting video. How about a video of how you tune the acceleration tables on a stickshift car in Tunerstudio? I've got my 455 turbo transam running pretty well, but could always use a little insight from the Master!
P59 QUESTION!!! Warning this question is of rambletronian levels and might sound like a cluster of ignorance. I have a 04 GTO ls1/t56 cable throttle body twin turbo set up ( it’s a swap) I’d like to for now run under like 15 psi ( if I swap to l33 bottom end, if not I’ll only push like 7psi ) I’d also like to run flex fuel because I’m a greedy rat. Am I straight up waisting my time using the p59 with the AIC chip ? I don’t wanna show up and have the tuner look at me like I’m from planet Rambletron of pure Rambletronian decent. By the way I think Sloppys play on the word ramble is pure genius.
If your doing just your own vehicle and everything is working seems crazy to do updates only to have issues. Esp being limited to parameters of the older stock ecm"s anyhow
I was thinking about upgrading from po1 to p59 on my 02 escalade but eh mabey not
Matt, have you ever got into the VIN numbers on the EMCs?
The numbers at the beginning of the VIN says where theyre made.
1- USA
2- Canada
3- Mexico.
All three of them use a different OS and all use theyre own O2 sensors and from what Ive found, they cant be interchanged.
I tried using the flat blade O2 sensors with a Canada ECM and it didnt work out. I had to get the corresponding ECM for the O2 sensors.
I have 2002 po1 ecu in a escalade how do i add flex fuel to OS ?
Hptuners needs to copy the hell out of that boost table. Lets email it to them lol!
And when you email them about it they say oh it s an older os and we dont give a shit.
thats if you get a response at all! lol
Wait so even after a segment swap that's all you get in the p59?
Yes
Let me preface this comment by saying I’ve never done any tuning, total newbie, just picked up a 98 Chevy van with a mpfi efi 454. I took the efi and heads off to put on a 502 short block for my motorhome. No boost, marine roller cam, headers and dual exhaust, 4L80e trans, 4.56 gears and 32” tall tires. Should I swap to a LS computer to tune the bigger motor with cam and headers? Run closed loop? My first step will be reading the sloppy wiki site, as well as some great stuff on the Chevelle site. Any guidance is appreciated!
Hey Matt have you tried ironing out the 210s fuel table on a 1bar os then flashing back to 3 bar? Although I tend to run closed loop I did notice my fuel trims were pretty on par between os's. I've also scaled the engine friction torque table to raise idle kpa and that helped
Mine says p59 parameter access operating system ids are different . What. An I do to get this to write this is only place I see this and it's on every vehicle I try to flash a tune. Driving me crazy trying to get this out. Thanks
Anyone ran this operating system on their boosted truck??? Did it work properly, no hiccups?
Across that side to the other side now both sides getting spark and it won't crank Puffin through the throttle body
Hmm, I'm pretty sure my P59 w/ 2 BAR has same resolution as that P01 2 BAR. I'm probably wrong though if you are posting about it
I think you’re right but flex and 3 is tiny
I have a P59 in my 2004 gto and I lost resolution going to a 2 bar os. I now have 30 to 210 kpa in steps of 10 all the way up.
P59 with 2bar switches from multiples of 5 to multiples of 10 as well as losing the first 25kpa of resolution off the top. P59 3bar does the same but switches to multiples of 20 above 100kpa.
Just checked my tune, I do not have the resolution as the P01
😉
I'm not sure the p59 is worth it for cable users. Flex is mostly irrelevant to a weekend/race car since it will rarely if ever change between fuels. Even then 50-80% ethanol use virtually the same timing. It's only worth it for an OEM or tuner that has a guaranty/warranty at stake.
i would disagree if its in your area its totally worth it to be able to mix the fuels worry free without re tuning anything
So you say there differences in the files I'm writing to truck but one was a read file and the other was a modification of a read that came from same so how did I get operating system ids are different p59 parameter access
The 59 can support the IAC from certain vehicles. The 04-05 ctsv is one of the .
On the custom os 105kpa on the second table is set slightly lower maybe those should be absolutely equal so nothing screwy happens?
good stuff
Have you tuned any of the LS Connect and Cruise crate computers { Chevrolet Performance} ? Is it the same as a truck computer? And why is the trans controller separate ?
Audio was way better on this vid. I thought a po1 didn't support 3bar now I have to watch the other vid again. I'm going with and trying to learn hptuners because my buddy wants to swap his car. He has cancer and can't afford a gold box which seems much easier.
I know you can run 3bar but I thought you said it cuts off at 2bar
You can't run 3bar and flex on a p01.
This vid delivers
Matt, do you know which ecu’s are capable of controlling vvt? I think 2010 was the 1st year for it in production trucks.
Would be nice if you could get a the better os thatworks with drive by cable or just ya since efi can find a place for it why cant hp tuners or have the option to remove something for that resolution
I have a stock Camaro computer and one side getting spark
Would love to have a look over the dual ve file in the video myself but i can't seem to find the same file name with your other tunes. Any way I can get my hands on it?
P59 dual VE it’s on the cabinet
@@SloppyMechanics in the Google drive tune cabinet? Coz I can't see anything under dual ve or p59. There is only a handful on the drive but checking the website as well there is nothing.
Matt, do you have a tune for a 2001 5.3 with just a TSP 228R cam by chance?????
Sorry to ask a dumb ?
Are you using OBS or still xsplit?
Both
I think your awesome and talk true
Thank you
P59 with the iac. P01 from an 02 flex suburban. I want to run 3bar flex,. Which would you use?
i know some time has pasted but have you had time to mess with the expanded VE table for the p59? also where cans i find the file to mess with? i dont see it in the tune cabinet.
thanks for the help
Have you ever tuned a first gen ctsv? On hp tuners I’m trying to changed the os to a 1 bar speed density tune and I pull up the os window and there is nothing there....
Can I do 2 bar and flex on po1 ?
Sooo glad you made a follow up vuh-jay-oh. Lol
Or p28? Ohh wait, we're not doing Honda's right now 😉
How did this ever turn out? Are people using this?
I’m curious about the same thing
Negatively working against you since 2018.
I got 2 p59 ecus for sale one has vats removed already the other is stock let me know
and your talking to who?this isn't craigslist!!
I'm crying because I legit did ask too lol
Chastise, chastise, chastise lol.. no link in description but another great video as always.. keep it sloppy
By the time I finish ranting I always forget!
Just added is it showing?
This
Sloppy Mechanics I'm not seeing anything in the description at the moment.
it is now thanks
One thumbs down.Always that one guy in the class.
Probably was a accident he or she meant to click the thumbs up. But while he was working on his lsx he dropped the phone and busted it. Now he can’t click the right buttons or afford to get it fixed from dumping money in car. This is all a assumption
Dual VE is a damn good idea
yeah it has some quirks though like weird PE/BE settings and other things that do not work like normal but it does have a boost spark table i forgot to cover also
Mr. Sloppy! I have a question, do you run your turbo truck closed loop? I thought I saw in another video of yours something about your o2's overcompensating for fuel or something, and thought running closed loop in boosted vehicles with the older computers is dangerous because the MAF is too slow or something (at least what I've read in forums). I'm still learning tuning and would love to know! Thanks for all the helpful info!
I am
Sloppy Mechanics Thanks for the reply! so it's totally safe to run the MAF then? Does it need to be rescaled for boost?
Hes not running the MAF. You can run closed loop with a SD OS as well.
Bad Luck Garage Oh, gotcha, thank you. So it's regulating fuel by the MAP table and o2's. I didn't know you could run closed loop without MAF. But I thought even the o2's weren't accurate enough to trust? Idk lol, I'm still learning. So the 2 bar and 3 bar OS's that you can select in Hptuners are set up for closed loop then?
Closed loop only occurs under partial throttle conditions. Under those conditions you’re commanding stoich which is what the narrowband O2s are designed to read. They aren’t used at WOT since you’re then in open loop and commanding something other than stoich.
