The 1227727 is a weather resistant ECM, mounted under the hood. It is most commonly used in W-bodies, and some Corvettes.
Applications:
1988-1989 2.8L V6 MPFI
1989-1993 3.1L V6 MPFI
1989-1990 3.1L MPFI Turbo
1990-1991 5.7L V8 TPI
Code masks:
$A1
$8F
Updated service numbers:
16197128
16198260
This is commonly referred to as a weather resistant 1227730, since the circuit layouts are very similar, and used many of the same features.
Many of the same bins can be used in the 1227730 and 1227749.
