ok, i tried reading some instructions on how do this, but i am confused as hell! i'm not sure what to tune for, i've heard to tune for no knock, 100 percent on the fuel trims, etc. i figured that i'll tune for 100 percent on the fuel trims (someone tell me what i should be tuning for!)

btw the thing the MAFT connects to is on the filter, not the intercooler pipe.

anyways, my fuel trims are like this

ftrl: 127.3
ftrm: 88.2
ftrh: 81.2
fto2: 100

these are of course in percent.

before i changed my idle on the MAFT 1.3 to one click counter-clockwise, it was around 90ish, and i think i did it another click to make it 127%. but how do i change the FTRM and H trims? i'm assuming that the mid knob is for the FTRM and the wot knob is for FTRH. which way do i turn the knob to get it closer to 100 percent?

if i'm supposed to tune for something else, give me a heads up!
 
Tuning the mid and high fuel trim is done through injector compensation (also called base setting). The mid and WOT knobs do not change the fuel trims AFAIK. I have version 2.01 so it might be a little different so if you need instructions then check this place out www.fullthrottletech.com/forums/index.php. :)
 
You need to go up on idle turn dial to right like three clicks or four but you are also rich on the mid and high.You can change mid and high with fuel pressure regulator or by changine base setting.You need to set your maft to higher injectors to lean it out.Mid and wot dials don't effect the mid and high trims these are just light throttle cruise and idle type of stuff.

So a bit richer on injector base setting.This will also bring up low trims.They say you don't need to be exactly at 100 think anything from 90 to 110 is good enough range .90 1g also have a bit different range than my 92.
