Re: Mods to '85 GM TPI ECM

["Jim and Sharon Brady" <bradyiii@shore.intercom.net>]

Mark,
    A 730 ECM huh?  From a Cavalier?  What year?  Would this ECM necessitate
the '86-'89 MAF burn off relay instead of my '85 Bosch unit?  I'm interested
in Supertuning and I haven't touched a thing yet so this woud be the ideal
time to make any changes.  Please let me know what are Gme Pro and Diacom.
I know one of them is a software package.
