    With all 3 values set like that it is basically disabled.
    But B0901 dictates which is used, MAP or MAF.

    Default MAF g\sec. ?

    Ross,

    I noticed while trying to enable the 3 timing tables via the MAF setting that the highest MAF value that will be accepted is 32 g/sec. on my '02 & '03 O.S.
    However on my '01 O.S. it will accept MAF values up to 256 g/sec. not sure why that is, 256 is better than 32...but it could be higher still, couldn't it?

    P.S. This stuff is so much fun it should be illegal? :wink:

    Thanks, Todd.

    Mmmm, the 02/03 O.S should not be limiting the value to 32, we will look into that.

    '04 LLY also has this problem...at least mine does. I only mention that here for the LLY so you don't have to follow two treads.

    Ross,

    Just curoius if you were able to sort out the irregular(& low) mass airflow values regarding the timing table switching? It really is a great feature if it can be utilized fully, I've played with it in the '01 O.S. Even more range (say 512) would be excellent their as well though.

    Keep up the great work,
    you guys rock, Todd.

    GM changed the code, I guess they decided they would be using MAP all the time so they made a change to the MAF setting with the result that the highest value is much less than what it used to be.
