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.
it still a ls1b ecu, but it's called a p59.
Ok so those are a 512k is the other VZ one a 411?
So ls1a ecu's were pre 1999.
ls1b ecompases both P01/P59 ecu's.
Pre99 & P01 is 512kb
P59 is 1024kb
P01 is blue/red connector
P59 is Blue/Green connector
Apart from some minor pin changes and slightly different shape on the green connector, it's almost plug/plug between the 2. You can file down green the connector plug and away you go
Ok awesome so are the P59 a simple plug and play? Or do some pins need to be moved around
There was a huge stink over on the Corvette forums about this and supposedly 1 dude had it figured out but wasn't talking. I need to update my software to view a ctz, but are there any weird tricks or asspain other than a full flash of that tune onto my P59 in my 2004 Z06? I picked up a blower for it and really want flex fuel ability.
There is a current thread on LS1tech.com regarding this, let me see if I can find it...
I think I saw it too. I'd found more info on the swap but apparently not on the Corvette Forum because when I checked back there I couldn't find what I'd remembered reading.
So basically we need to run a vz ls1 ecu but then we have the problem of dbw
I reckon the Yukon is still cable that uses this PCM so should be able to use that OSQuote:

So I’m shifting through all this and I’ve come to the conclusion....
There is no way to do a COS on a the flex fuel operationing system for the p01 pcm?
You have to run the P59 PCM.
