    What are MAP Old 1 and 2 used for?

    Under Airflow>Dynamic what are those coefficients used for?

    More or less I'm trying to see how those values are applied and if they are applied durin pure SD use.

    Thanks.

    i think there is maf, ve and then dynamic......... dynamic is not the same as ve....

    dynamic by looking at is simply a airflow prediction table that predicts airflow via map, throttle etc....

    personally i wonder if this throws out ve and maf tuning... i know you can disable dynamic that then disables VE? or does it....

    at the end of the day it's only really about getting air fuel ratios where they should be.... by mostly any means ........ but even so it is annoying. your gt is i think a l76 engine the same as my ve ss here in aus

    It's part of the DYNA_Air logic for filtering MAP values.

    If they are exactly the same thing, Chris covered them here some time back:
