    1227727 ECM information

    *This is a work in progress*

    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.
    The man who says something is impossible, is usually interrupted by the man doing it.
