ok ive tried both ways for maf tunning the one where u change the main ve and the other way and maybe i just really dont get it, but its like none of them work... is there like a maf tuning for retards out there?

Josh, could you post a scan and your current tune for us to have a look at? I'll try to give you a hand with it bud....

if there is such a guide.. order me one cuz im confused tooOriginally Posted by Josh Hapka
Which "other way" are you refering to? Changing the main VE table will have little to no effect on fuel trims with the MAF sensor enabled on most cars, so I can see where making changes to that table did nothing.

Ding, ding, ding, we have a winner! If your tuning VE then you MUST dissable the MAF or fail it. If you are working on tuning the MAF the only table you need to adjust is the MAF table and below 7500hz until you get your "0" trims. Again post a tune and a log Josh, let's see where you are bud...Believe me, I'll be the first one to admit how frustrating this can be

ok here are the scans... i did 2 scans, one was with the jet performance intake air temperature sensor and the other one is with out.....and i got another random question... is the jet performance intake air temperature sensor (ats) really help or does it make me lose performance?
Post the current tune also.

k here it is
In those two tunes you are running rich at part-throttle, indicated by the negative LTFT's. If you are rich, you need to DECREASE the MAF table values. I would multiply the MAF table cells 3000 through 7500 by .92 (that is 92%) and scan again. That should reduce the fuel and bring LTFT's up.
The concept is simple: If you tell the PCM that the MAF is flowing more air, the PCM will add more fuel, and by indicating less air through the MAF, the PCM produces less fuel.

well here are the scan after i did what u said BlackGS, and at the end of the scan i did a wot blast.... to tell you the truth i thought i should be pushing more out of this motor than what it says for ft lbs of tourque considering just stock it should be running 225..... expecially with the mods ive done.....here are the mods
pace setter headers, custome intake, ram air, throttle body spacer, 160* thermostat, msd coils, msd wires, bosch plugs, royal purple oil, k&n oil and air filter, manual fan switch(like that matters), and a jet performance air intake temperature senser(not sure if it helps or it hurts) 2 1/2" with high flow cat and borla exhaust and trying to computer tune it, and through the scan i only see like 183 tops... wtf.... oh it is an auto, it is a 2002 camaro. w/106,000 miles.... here is also the stock tune, to compare with.... wut are ur opinions,
