    Default Couple of Auto VE questions/observations

    In Auto VE, my 0% TP decel always is 11:1 rich and drives the 0 - 35 Kpa values wayyyyy low...like 7.0 - 10.0

    Then the "cell averaging" makes the idle strange. Easy fix since I now ignore the very low kPa bins....just curious if anyone else see this?

    Also noticed that if you start with an overly rich VE table the auto VE can cause some "cell averaging" problems if you don't manually adjust the higher cells.....say 4000rpm kPa 60 is 72VE, If 4500 is 105 things get skewed by the cell averages even though you may not "hit" 4500/60kPa to correct the value with a bin..

    I believe this is what I'm experiencing.

    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.

    i filter out TPS < 2% because that's fueling done based on RAF and IAC figures, and have little to do with VE proper.

    Can you explain how you filter out under 2% TPS.
