    Default Maf (gram per second)

    Hey guys was playing with my mates VT commodore, with EFI live V4.
    I was looking at his Maf frequency V Gram Per Second and noticed that his GPS was way out.

    At idle the GPS was at 60-80 and if you were to rev it to like 2500rpm it would get maxed out. (300 gps.) owe and it N/A STOCK.
    Far as i know it should be around 6-8 gps at idle.
    The frequency of the MAF sensor is as follows at idle 2300hz which is normal and when accelerating it goes up steady.

    Does any one have a Maf frequency v Grams Per Second chart?.
    My mate said he is getting realy bad fuel consumtion i think this could be part of the problem.
    I will look at the LTFT & STFT tonight.

    Has any one had this problem.

    Yeh thanks mate.
    I went in the Def file and changed the factor. It reads fine now.
