Remanufactured over rebuilt
I have a 2005 Jeep Grand Cherokee limited
with blown 5.7 hemi magnum motor and I
am replacing it with a remanufactured
motor do I need to have the ECU orPCM or
what ever flashed or reprogrammed I'm not
trying to change any factory settings just
put a new motor in it or is rebuilding a
better way to go
