It's 2002 os 12216125. Was used in flex fuel trucks in 02 and I believe 8.1L trucks as well. I'll post my 6125 bin that's currently in my truck. I could also pm you my xdf if you'd like. I'm hesitant to post it bc it's still a work in progress and I know of some errors. But does have most everything defined.

Sorry if you already started swapping everything over, but I'm going to start porting all my code to 12216125 as well (It might be a week or so until it's done).

If you are willing to test both that would be great.

No worries, I like messing with this stuff. I will definitely test both if it'll help. I know your getting rid of the EGR code, but will the PCM still read the EGR pintle pin for my wideband? If not I'll feed it to ac 5v.

Yeah, I made sure because I use the EGR input for my wideband as well.

Just to let others know who are watching this thread. I have bubba's "LS1 Boost OS" running in my vehical.

Hope to start the tuning process tomorrow. Have to decide on what logging program to use. Is there a TunerPro ADX for 12212156?

Could use HPTuners or EFILive.

Just finished a log on the road using EFilive. Car has Wideband but EFILive not set up for it yet.

Engine started well and Idle was good. Engine coolant was 13*C. Drove round the block watching my onboard
Motec Wideband and with higher loads upto 100kpa was running too lean. Will get wideband installed on EFILive
or HPTuners before I do any more tuning/logs

You have done a good job bubba

Good work. What turbo and injectors are you running?
I have HPT here so watching!

Turbo from memory Garrett GT35R Dual Ball Bearing. Injectors 800cc Sard. My previous bin was a HPT COS which worried me as I wanted to go al least 25 psi boost and be in control of spark timing.
Now I can with bubba'"s "LS1 Boost OS.

Ok, I just discovered a mistake I made which prevents the EQ ratio table from exiting closed loop. It should be a fairly easy fix, but I'll test it on my truck to make sure it works.

I'll have to send you and updated file to flash once I fix it.
