Does anyone know what GM car this chip is out of?    Delco AMAH 7140...    1A7309

Thanks!

AMAH =

1988
A-body
LB6 (2.8MPFI)
3T40
2.84 final drive
federal emissions

i don't have the BIN of it, but it's probably a $55 BIN, meaning it is a MEMCAL that still used the flaky MAF sensor that was eventually disabled.

Thanks for the reply..   That sounds like the car it came off of.    I had never seen the AMAH before and wondered if it was off of a different vehicle.
