Part Number Revisions:
Certain ECMs were re-released with different part numbers. There may or may not be slight changes
in the internal parts, but they are interchangeable. They may even be just the numbers that are
assigned if it is a re-manufactured ECU.
1227730:
- 16196404
- 16196344
- 16198262
1227727:
- 16197128
- 16198260
Certain cars were set up to use ethanol/methanol/flex-fuel from the factory, as far as i can tell, the
only models that had this option are 1991-1992 Luminas. They use a 16153084 ECM. It is
externally identical to a 1227727. The known BCCs that use this are: AXAW, AXFX, AZRT, BAHA,
AXHT, BCDS.
