GM MAF+T tuning questions
« on: March 02, 2006, 10:43:22 pm »
i am still a little bit foggy on how to tune the GM MAF+T.  now i understand that u adjust the idle knob for idle   now, what should i be looking at to adjust the mid and high knobs?  am i looking at the mid fuel trim (again aiming for 100-110%) for the mid knob and then just a .96 O2 voltage at WOT (closed loop) for the high knob.  and then if they are all either over or under, then u can adjust the main knob (the one used for selecting injector size)

thanx

trev

p.s. i'll try reading over the manual again, its been a couple months, maybe something will click
o more DSM, 1990 JDM MR2 GT - Turbo (T-Top) on the way
