    Looking for P59 ECM and OS to run flex fuel AND must be DBC

    Hello,

    It's been a while... I'm getting back into tuning and of course my first project is on the gen 3 platform where I have less knowledge than gen 4 setups.

    The project I'm working on is an LS swap which will be utilizing a P59 ECM. However, we're trying to find the correct hardware and OS to support both a flex fuel sensor AND a drive by cable setup (IAC)

    Any suggestions for accommodating this?

    I keep seeing OS 12579405 being mentioned but have also read that certain P59 ECM's have the hardware required to drive the IAC while others do not, so I'm hoping someone can point me in the right direction on what I should be looking for. I've also read some of the 2006'ish Express Vans had a DBC/IAC setup but some of the others do not.. but that's about all I've found so far. Not sure what particular hardware I should be looking for and would rather not go through a bunch of guessing/hoping for the best.

    Will hardware # 12586243 work?

    Any help would be much appreciated.

    Thanks,

    I found one that worked...

    Attached is the base file I used in case anyone ever needs it. This is for a P59. Flex fuel works and DBC works as well (obviously need the correct hardware as well to drive the IAC motor..) but it worked great.

    I used it on a manual transmission but appears it has the auto stuff in there as well in case you need that.
