Thread: Swapping in distributor for timing control.

  1. #1

    Default Swapping in distributor for timing control.

    Two questions. At what percentage of Learning do you slow the rate?
    And, how long should I wait till I install the new distributor and hook it up for timing control?
    I've driven the car twice now with the Sniper and it seems to be working fine so far. Robert

    When the Learn Table values stop making significant changes, the ECU is finished self-tuning. You can install your desired distributor at this time.

    This would seem to indicate that one should be monitoring the Learn Table. I don't have my handheld hooked up, because I have yet to find a hole in my firewall large enough for the cable plug to fit through. I've been just driving it around and not really watching what it's doing. Is there some sort of reading that I can check at a glance to see if the Learn Table is slowing it's adjusting?

    Yes, the "Learn" parameter on the 3.5" TSLCD or the Sniper EFI software. The Sniper EFI software is preferred, so you can see the entire Learn Table.

    Does it say anywhere what version of the EFI software/ECU firmware is installed on a particular unit?

    There's only one EFI software/ECU firmware version (no updates yet).

    Is there a running datalog of the Learn Table that will show me the progress of the Learn process, from the first start to current activity?

    No, but the datalog does display the current Learn values. The Sniper EFI software is preferred, so you can see the entire Learn Table.

    So I buy the communication cable and download the free Sniper EFI software, and then I hook it up to my laptop to see the full Learn Table?
