Thread: Newbie from Georgia

    Default Newbie from Georgia

    I just had the new "Sniper EFI" installed in my 1969 Dodge Charger R/T SE 440 4 speed. The system is in "Learning" stage. How long does it take to "Learn"? I drove the car around for an hour and it is only at 18%? It was above 160° coolant temp. Also, is there a way to RESET the entire Learning process? Thanks, Jon

    When the Learn Table values stop making significant changes, the ECU is finished self-tuning.

    The purpose of the Learn Table is not to achieve similar values, high/low values (0% or 100%), or any value in particular.
    It's simply indicating the amount of tuning applied to the Base Fuel Table. Read this thread, that's what it's all about:

    You need to read the Sniper EFI Instruction Manual (LINK).

    Thanks Danny. Sniper chip had a corrupted file according to Holley. So my mechanic downloaded all of the software files again, and the car runs amazing now. I would recommend this EFI system to anyone looking to change over from a carburetor. Next steps are new air intake, manifold, headers & 3" inch crossover exhaust. Need to let the 440" magnum breath.
