    one question Joe, to add more fuel in maf mode, do you add to the maf tables?

    In MAF mode, for any RPM above B0120, you can add to the MAF table... below B0120 the PCM uses VE and/or MAF (you can't tell which) so you have to add to both... or if you set B0120 to zero then you can add to MAF table only... or instead of VE/MAF adjustment, you could subtract from the IFR table.

    Thats what I thought but was not sure. Thanks Joe. Not looking to hack at those but was making sure I knew which way it moved to go rich or lean.

    Hey Joe, for shits and giggles I got out my old Maf translater. I added 10% at base and 14% wot and at base it is damn near perfect idleing around 15/1 and when I rev it it goes in the 13's. I have not tried to run the car down the street with wot but I figure I would go real fat and work my way down.


    The reason for this is less flashing untill i get an Idea of what the car wants and then flash it into the maf table. I am trying a full Maf tune on it where it is not using the ve table at all. SO far , when I cranked it cold this morning, with 10 % added to the base it cranked with out me touching the throttle and idled great.

    For a 239.243 cam it idles absalutely perfect with the maf tune. SO I am not touching it untill I go to the dyno in a couple weeks where I can actually play with a ve tune.
