    write calibration failed in 1998 v6 vortec silverado.

    i reflash this ecm with other vehicle, chevy silverado 1500 v8 1997, but the ecm i reflash is from a 1998 chevy 1500 v6.

    i cant write the reprom file over the ecm.

    i try with doors close, accesory off and good battery voltage.

    can anyone have this problem??

    thanks and grettings from Chile

    We do not support 97 silverado pcm's.
    It doesn't have to be perfect, it just needs to be done in two weeks...
