    Cool Gen IV ECM Types

    Wondering what type of ECM you have in your GenIV vehicle?
    Lift the hood and take a look...

    EFILive currently supports reading / programming & locking of the all the GenIV ECM's.

    E40 was the first GenIV ECM to be used.
    Some specs - 2 x MC683xx CPU's, 1Mb Burst Flash memory.

    E38 I think was first used on the Z06 and now on many other 2006+ vehicles.
    Some specs - 1 x MPC561 CPU, 1 x MC9S12 CPU, 2Mb Burst Flash memory.

    E67 is the new ECM used on many 2007+ GenIV vehicles.
    Some specs - 1 x MPC565 CPU, 1 x MC9S12 CPU, 2Mb Burst Flash memory.

    Cheers,
    Ross
