Maft pro

Slowly getting this tuning done. There are so many points you can adjust @ 1/2% increments.

Main scale is adding 4%. When my 650s come in, plan to switch out the stockers & send them out for cleaning. Also have a "lazy" front o2 sensor but she seems okay when warmed up. There is some quirkiness I am attributing to needing injectors serviced. Part of the issue is that she is a DD, a lot of short trips and the odd temperature swings we have been having; 60 degrees yesterday.

For low load, I've added to idle range, and in process of removing fuel between 1200 & 3000 rpms (cruising) aiming for o2 trims @ 100. I am targeting 100 for low trims (and eventually all trims).

Maftpro has a partial throttle(pt) setting. Only works with NBs unplugged. no cel

Nb free so far & loving it. Friggin things made me run rich @ idle & cruise in spite of cycling ok.

Expecting to get some mpg gains.

Wut??? I got a cell while cruising...she immediately seemed to run more sluggish. Evidently a limp mode issue that happens periodically.

I reset ECU (pulled 10 amp fuse) and she seems right as rain ATM.

Additionally, this worked for accessing MAFTpro via laptop>>

Will save settings once its tuned in reasonable and then update software/firmware to the latest and start tuning again =P
