Im working with a swap vehicle. 5.3/4l60e out of what I believe was a 1999 silverado. The wiring was all complete and pcm installed when I got the vehicle. Under the Calibration details it comes up as a with the VIN for a 2001 S-10 4.3 but in the tune data is shows a 5.3. Just wanted to confirm this is the correct OS 12208322 to run this setup???
Also, Im not getting any readings from the o2 sensors. Could the pcm possibly have been pinned incorrectly or could the pinout changed based on the current OS that is being ran?? I hate trying to clean up other peoples messes
Thanks in advance
