    Default Strange timing issues

    Can anyone see in my tune why I don't seem to be pulling the IAT spark it's supposed to be?
    Is it an OS issue....or something else?
    EG...Frame 3734...
    Log says 13.0deg spark.
    High octane table says 12.8deg
    IAT spark says -5.01
    So....I should see 7 or so deg of spark....not 13?????

    YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
    MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
    DUCT TAPE.
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

    Howard,
    Look at B5944 spark/IAT multiplier. That value at 78c is 0. Times that by the -10 degrees in your B5911 Spark IAT table and you have 0. Change B5944 to a 1 at that temp and you should pull 10 degrees out.



    Now can you help me with my problem? Why is my BEN reading A/F instead of Lambda???????


    Thanks,really! John

    Thanks John,
    I've set it to 1 across the board..we'll see how it goes now.
    Have you set your properties to display Lambda?
    Go to edit, properties and select Lambda.
    Make sure in the scan tool you've selected the correct Map.
    Shift + cntrl + M.
