    Default 85mm MAF calibrations

    I would just curious, would it be a good starting point for tuning a car with a 85mm MAF by using a stock Z06 MAF table, since it has a 85mm MAF from the factory?

    Or, is there a better way?

    Thanks! Chris

    AutoTune in SD to dial in VE table, logging DYNAIR and MAF FREQ as you go.
    When VE table is dialled in, DYNAIR vs MAF FREQ is your new MAF table.

    So, if I can't use the SD autotune for this particular car.. just dail in the VE the old school way and then log DYNAIR and MAF FREQ in SD..then make a table that is DYNAIR vs MAF FREQ and use that for the MAF cal?

    Sound correct? i'm a newb.. lol

    The MAF has to be ignored while tuning the VE table (i.e. require SD mode).

    Whether you use a WBO2, NBO2, and/or AutoTune, is up to you.

    If you don't have a WBO2 you may be able to get by, see this...

    If VE is dialied in, then DYNAIR vs MAF FREQ give you your new MAF table.

    Cheers
