I got the 08 in, and I did order an 09 ECM as well, as well as an 09 12R main harness, with a 09 CityX throttle body assembly. Of course I got some other ideas I need to look into...I see a couple spare pins...
I will try to power up the ECMs and see which firm wares I have.
Thanks Cooter, I did throw your name around and after assuring him we don't know the same cooter he finally talked to me.
