Thread: Procedure After Removing Battery

  1. #1

    Default Procedure After Removing Battery

    I need to disconnect my battery to charge it. (I don't think my alternator is keeping up now with the extra load of the EFI pump, but the battery is pretty old).
    I'm guessing the ECU will have to be reprogrammed? Is it just a case of key on and load your chosen Config File, or do you have to go through the Wizard again? Thanks.

    No, it shouldn't lose its Config File. Although I'd save the current Config File to the SD card, just in case anything is lost.

    I thought I read here somewhere that it lost its memory after 20 min. Must be mistaken. Thanks for the clarification.

    Completely disconnecting the battery for 20 minutes, sometimes "resets" some unusual ECU issues. This may be what you're thinking of.

    FWIW, I often disconnect my battery for long periods and have never had a problem.
