I am no expert when it comes to the E38s, but I have had success with running them stand alone a couple times in the past. This one is giving me fits though. Can someone tell me why this tune won't fire the engine?
2010 Camaro LS3 Manual trans E38 Modified.ctz
This started life as a low mileage ecm from a wrecked 2010 camaro, like I said, 12635863 OS. Manual trans. I made the vats changes and applied patchs that I think are right, and tried a couple other things as well, can't get it to fire stand alone for the swap.
I have another stand alone ecm here with an automatic 12635863 OS file that was tuned by a buddy with HP, I can connect it to the harness and the engine fires right up. So my next step was to copy that file and put it in my e38. Using this tune in my e38 the engine will fire but after a few seconds puts up a p0606 code and goes into limp mode killing the electronic pedal. But for the life of me I cannot get the original 12635863 manual trans file to fire in its original ecm. I've tried vats 2 and 3 with no change. Do I need to put ground or 12v+ to a pin beings this is a manual?
