Does anyone have a stock tune file for a 12216125 OS or any other OS that I can use for flex fuel in a LS1b PCM.

See if you can find it in here: Tunefiledepot-has-been-replaced
Yep found it in there thanks again joe. Does anyone know if there is a flex fuel enabled GM OS that is also custom OS enabled for boosted applications.
Yes, but I dont believe for 512kb LS1 PCMs with EFILive. You'd have to go to 03-05 1MB LS1B PCM to get that.

Do you have a OS Number? Or what year and vehicle it came out of. The PCM I have is a LS1B as far as I know. From a 2003 VY commodore
get a vz ls1 1mb ecu, then you can run e85 compatible os.
I'm pretty sure i have posted a base tune on the forum here already with e85/custom os

ok so the VY PCM isn't a LS1B? That sucks, might have to source one for mine as it will be boosted the other car I'm doing is a Holden 355 running the LS pcm using a low frequency trigger.
