ok i got my a/f meter workin, at wide open throttle i am getting readings of about .72 consistently, when i let off the gas it dropps down to .01 is this how it should be?

 

At WOT... should be rich and nothing else. By carefull.
check out if your O2 sensor is ok. I mean is it fairly new.

A bad O2 sensor could cause the car to run really lean as well.

best wishes.... jc.

 

so you got the apexi timer workin i guess? .72 seems kind of low at wot but i have serious doubts about the accuracy of that timer/meter... often times the o2 reading will not match up w/ the readings i get w/ the pfc. from what i've read though, less than .87 at wot is running too lean. i have a pfc w/ the base maps which most people say should be rich but sometimes i get some strange readings from the apexi timer/meter.
