Not to mention it didn't want to down shift when WOT, unless I manually shifted it down. Didn't have tuning software at the time and wouldn't have known to scan it for that anyway. Interesting Idea though if it would allow us to calculate MAF Pre VE tuning!

Well I calculated my VE table yesterday and got it perfect for my tastes(screen 1). I then plugged the MAF back in and all my values went to crap as expected (screen2). Then I figured I would use the monaro table and see how close it got me when I changed my MAF values. (screen 3) It got me negative but too far negative. I had calculated new values for my MAF with RedHardSupras spreadhsheet and so I figured I would plug those in. Screen 4 is after plugging the new values in and massaging some of the values below 3000 Hz to get the trims in line. Screen 5 is where I was this morning. All in all I am fairly happy except my piston slap has been getting louder the more miles I drive and is frankly driving me nuts. Now on to PE when I get a wideband.
Here's my trims after almost 2 weeks from doing VE and spreadsheet MAF calibration:
Not really sure why my idle/slow down to idle is always rich, but as far as the rest goes it's fantastic! Nevermind the lean spots at higher MAP, those were not sampled very much. The circled area though is my main part throttle driving experience. Was tuned in 60-70 degree weather, today is 70-80 degree weather (not too far off!)
Another thing to keep in mind, your trims change day to day so if you tune close to zero today, don't be suprised when things show differently later. As long as they don't swing too far off, then you're just fine!
