X15 swap with isx 2250 problems.

[Kiko]

Thanks for the input Rawze. I’ll talk with this guy and see what he wants to do. I’m sure right now he will be looking for fastest and easiest solution. I should have mentioned that he had bought a harness from some outfit that builds convert harness’s for this engine to work in this truck. That being said could we not just program the current 2250 ecm to work with this truck. As far as I can see right now everything else is reading and working. If not then we can swap the ecms and harness back to the original and change that program. Also I believe that the original ecm was demandated, would that matter.
