I have paid 2 different "Tuners" (one was a shop with a dyno) to make this thing run. And it's barely derivable.
Nothing special at all it's just a bone stock 2019 4.3L with a TH350, all i really want it to do is run like it came from the factory.
Ended up replacing my old EFI live with HP tuners to just do this my self but i need a bone stock tune file for a 2015 (the newer the better) and up 4.3L to get started.
I looked through the one that is in the tune repository but it looks like it has been messed with quite a bit.
Any body have or can get a bone stock engine tune for a Gen V 4.3 ?
If needed i will pay for it in lieu of buying another ECM just to download the tune.
Need more info about the ecm your using. Im guessing this is a swap tune your needing? or help building one? Im not on here very often but will check back on this in a day or so
Chris,
ECM is E92 with a 12694524 OS from a 2019 Express Van with an LV1.
Yes this is for a swap into a ground up off road rock crawler.
The good part is the last "shop" that put a tune in there actuality put a true manual trans tune in the ECM, unlike the first person that put a tune in. All he did was change the trans setting from auto to manual. Hoping to find a truly stock 4.3L LV1 or LV3 that i can do a comparison on and just change all the necessary tables (VE, MAF, Spark, Torque, etc.) so I have a truly factory stock tune i can start with.
Any help would be appreciated.
Thanks, Jim
Update:
Ended up buying a E92 ECM from Junkyard from a stock 2019 Express Van so i would have a completely stock LV1 file to start with, now i gotta start tuning.
Going to post this stock file hoping it will help someone.
