I can read the PCM fine on the bench harness, & the vats is/was disabled in the tune. The car (holden vy clubsport) fires then dies as like it needs a VATS relearn done. However
when connected in the car efi live can't detect the pcm, can't read/write or change vin etc......
Suspected the BCM maybe faulty but would that cause the pcm comms to be affected?
