not sure if this is a issue or not but i have a 2006 gto ls2 that i am swapping into a 93 truck. heres the potential problem i went ahead and powerd up the ecm&tcm on my bench with the original harness and left all the sensors unpluged, i figured id just get a bunch of codes for all the unplug sensors, but that is not the case in fact only codes i get is lost comms to bcm and another module, so i went ahead and pulled the stock calibration and added the vats patch and did a full flash. (loaded the full flash with no errors) so i guess my question is has anyone ever bench test or bench programmed a e40 ecm and have no codes with no sensors connected?
