    Hi myburb

    Does this help any? This is for TBI I think. Does he have CPI or TBI?

    It could be a red/blue connector PCM like a 16197427 or it could be a vcm like the 16193495 which is flash based and has little to no support. If it is a red/blue PCM you can try an $E6 or or an $0D adx and see if you get any data from a datalog. From what I have read, the 16193495 uses a crank sensor on the timing cover like the 1996 and up engines yet is CPI with the tuning valve in the intake.
