Using the GM flex fuel sensor on an Fbody
The Best V8 Stories One Small Block at Time
No It won't work on P411. And 2004 GTO don't have Flexfuel application.
Delphi PS10081 3 bar map sensor (12223861)
2005 GMC Savana ecm and OS
Hptuners 3 bar OS
Flex fuel settings enabled
or use OS from 12216125 but be limited to 2 bar with the red/blue ecu? Pin 56 is for flex fuel?
dont have AC, so dont care about that.

can you generate XDF's? I'd love to get an XDF for an efi live COS based on the common p59 xxxx7603 OS
For those of you still fighting for the right OS that will do flex fueling and has 3 bar OS's available, Chris has two bin files in that .zip
One is for the common 7603 express van OS, the other is a less well known 7604 OS which is the only OS that also features lean cruise.
You must have a way to open bins and convert to your flavor tuning file,
Or you can have pick of the ones presented as .hpt files below. The first is still a NA tune, MAF on etc. The second is a 3 bar OS, which just happened to make 1074hp at the wheels with a 6.0 80e bosch 210's and a china billet s480
