help with dynotune wideband it was installed 2 days ago and was working fine. now its reading all over the place .9-10 etc... im tryin to figure out what i need to do to recalibrate it. do i need to unplug the o2 sensor and go through all that crap again? anybody have this problem with yours?
Your AFR on the wideband should be bouncing around some. My LTFT are within 1% and my wideband bounces around from 14.2-15.2 driving with giving it throttle and letting off the throttle. AFR takes about 20 sec. to settle in at idle when it is 1st started but settle in at 14.4-14.8 as seen on my wideband.

Did you install the red momentary switch for calibration? If so, you should try an open air calibration. Mine started reading wrong after I unplugged the 02 to hook up to the dyno (their 02 took a dump the day I was there). I did the open air calibration and it fixed it.
You will have to do the fresh air recalibration, then it should work fine. Mine does the same thing but the one I bought was defective and I cannot get the person I bought it from to take care of it. Should have bought a new one!!!!!!!!!!!!!!!!!!!!!
