    Default Anyone tuning MErcruiser ecm's?

    I have the MEFI 3 computers in my boat & am wondering if the EFI live stuff will work on these. I am thinkinng of purchasing the EFI live tool & I undrestand that I will need a 3rd license to tune all the ecms. Anything else I am missing?

    EFILive does not work on the MEFI's.
    We may offer support for them in the future.

    Something to think about.
    Go get a harness/PCM #12200411 from a 2001-2002 Chevy Express van or GMC Savanna, or S10, same vintage, and convert the harness to your Ramjet/4L60E setup.
    I'm doing one in a 41 Chevy pickup now, and S10Wildside is converting a TPI in a S10 pickup, and some guys are converting the 96-99 pickups to the 12200411 PCM.
    EFILive supports that PCM and you can do vertually anything you want to it then.

    Missed the boat part.
    You'd have to disable the trans stuff I guess.

    Or load up an OS for a manual trans setup.
