Default MAF x 118% and this is what i got....

under part throttle (30% throttle position) the ltrms where around 6 and under WOT they were around 10 (before editing they were around 18 for part throttle). The o2 sensors are now around .92 whereas before they were close to .88.

I multiplied the MAF tab by 118% and scratched the COT and the egr/air.

How can i get the ltrms closer to 0. The MAF is already heavily distorted. Is there a way to mess with the PE mode without a wideband?

mine where 18-23 under normal driving and i x118 the whole table and got them to 0 to 3 normal driving...

I wouldn't recommend big changes to your MAf or your A/F curve will look like this! It doesn't really go lean, the wideband just shuts off from being too rich. I went back and tweaked the fuel injector table, and it made a big difference. Now I am actually a bit lean at WOT (need to get back on the dyno).

Just my 2c.
