I have a tweecer and a plx m-300. If I have the meter set properly and computer is running closed loop with adaptive, should the wideband be reading a solid 14.6 all the time? The reason I ask is no matter how much I dink around with this maf function, I still get my wideband changing a lot. The only time it really sits still is in cruising speeds. This task of tuning a maf is becoming a real headache. No matter what I change, the next datalog shows sections running as rich as 11and as lean as 16. I am also clearing KAM.

The wideband will not read the same exact reading. At idle mine will be anywhere from a mid 14- 18:1. When the motors cold, it'll be in the 20:1 range for a little bit. AT cruise its usually between 14 and 15 ish. At WOT once it settles after the initial WOT hit, its in the 12's-13's.
That depends what your tuning. Idle, part throttle and WOT. For part throttle the eec should adapt itself so its good. Idle you may have to tune yourself. Just play with it until it idles good and will start up and idle with out any surging. For WOT n/a, I try to tune so its around 13.0-mid/high 12's across.
