i bought a new ecm and tcm for my truck (e67 2009 colorado 5,3l a4)
so that i could chang them out and tune them and keep my stock one.
that way if i bricked it i would have my stock one to put in. i installed the to computers and got a p1631 code and the crank relearn code .
the problem is it will not even turn over the motor . so my question is what do i do now?
here is my stock tune and the one out of the new ecm
thanks for any info on what to due
