1227730 ECM information

*This is a work in progress*

The 1227730 was used in many applications, including J-bodies (Cavalier and Sunbird), F-bodies (Camaro and Firebird) and others.

There are many code masks used in this ECM depending on the application.

$A1 and $88 were used with many FWD 6 cylinder applications.

$8D was used in RWD applications most commonly in the F-body.

Applications:
1987-1988 2.0L L4 TBI
1987-1989 2.8L V6 MPFI
1988-1994 3.1L V6 MPFI
1990-1992 5.0L V8 TPI
1990-1992 5.7L V8 TPI

Updated service numbers
16196344
16198262.

Many of the bin files used in this ECM can be used in the 1227749 and 1227727 as well.

There is a modified code for this ECM based on the V8 code of $8D. Most specifically the BIN file of AUJP was the starting point and turned into what is called S_AUJP (Super_AUJP), that includes many enhancements, including extended VE tables, WBO2 datalogging and other additions. *more info will be added and files*
