what am i doing wrong? maf tune

[goodwrenchdave]

Ok so this is a frankintune, basically took tunes that sort of worked and tweaked them a bit to get vehicle running. It seemed to run ok, start ok, idle ok in park and gear... so went ahead and decided to proceed: maf tune first (then later will vve)
trying to follow maf tuning then paste special half and its getting worse - much worse, not better- what am i doing wrong? are my decimal places or units skewed? any help appreciated, any comments on tune very appreciated as i would like to get the vehicle to a tuner in one piece- is my PE ok?

ZL1 supercharger on 2008 G8GT stock pulleys zl1 map, g8 maf. btr pds2 cam.
the fist tune I copied, pastespx half and it seemed to idle half decent.... went around the block..... started having hard time idling (coming to stop). a double pedaled back, pastesp1/2 again now having hard time starting..... i think my problem is my decimal point is in the wrong place in the math maf error % reporting..... how do i fix? I mean I cant be 64% error etc. maybe 6.4%?

update: well, after looking at a few logs (and it always runs best with original maf table)- it is obvious that somehow VCM editor is not reading my wideband properly (if i look at my stock o2 sensors)- somehow seems almost doubled? in the car the wideband displays closer to normal. its an aem 30-0300 feeding in my computer via rs232 to usb. any ideas where i messed up?
Thankyou for any help

I was just in a thread last night and it ended up being because he was logging AFR error and EQ ratio error at the same time and the scanner was averaging between the 2
His was an LM2
