My A/F guage is ******* with me i sware...it is hardly in the Green while cruise it sweeps only the red ans some of the yellow. It rarely sweeps up in the Green, and at WOT its in the yellow. Thing is if pull my plugs they look rich with no signs of detonation...just dry black look on the electrodes(like a real fine black powdery look)

I have the AFC hack and even have my settings set very liberaly -26% Correction.

NOTE: i have a dsm fuel pump rather than the recommended walbro 255lph.

So your answer is that its not acurate cause its a narrow band o2 sensor??

This setup used to work, a while back it worked fine...my next step is to put a new bosch o2 in although this one is only like 6k miles old.

I used to have the wire routed by my MSD ignition and i'm thinking it might have been cross talking alot with the coil and possibly ruined my Gauge....we'll see when i put the new o2 sensor on.

either way its not gonna be accurate becuase its still gonna be a narrow band o2 correct?
it might have read differently before, but i bet not accurately as it would on a wieband .?
to me , my a/f gauge is a nice light show. thats about it . no reall indication of lean and rich .

I totally agree, I don't even drive the car, saving a lil cash for peak and hold EGT right now to tune it...also already have a 5 wire o2 so i will probably buy the diy module and display.

Just wanted some ideas on why its doing that just becuase it annoy's the shiot out of me.
