    Default LMM Analog MAF Flow rate Table

    Well folks, every time I take the truck down the track I end up with an overvolt code from the MAF p0103. Looking at the MAF Flow Rate, Analog table in EFI live I believe I have found said issue but I was hoping for some confirmation. As you can see in the table at 4.84 volts i'm getting a maf flow rate of 602.39, then at 5 volts I have a corresponding 681.58 maf flow rate. I believe the problem is arising from the drop after this showing 5.0 volts all the way down the table registering with a 477.78 grams per second flow rate. Please see the picture below for a clear view of what I'm talking about. Any input is appreciated, thanks gentlemen.

    Edit: Running sdp twins, s475 over stock.

    If i am guessing, something in your script did that to the table. I just ran the D5 upgrade in several of my stock tunes, and it did not modify that table. All the 5V numbers should be the same (refer to the stock tune).
