AFR not changing
Ok so i have a serious problem. I have a wide band sensor and during normal cruising the guage reads 14.6/7. Which i believe is fine. The problem is, when im on boost, it STILLS reads 14.6/7. Any suggestions?

yea sounds like bad sensor or disconnected sensor/wire. Had that exact same problem with my AEM eugo this weekend. was working under the dash and pulled the wire by accident and pulled plug out of the gauge. plugged back in and it worked. it will probably fluctuate more than .1 even if the tune is bad.

the AEM does use a Bosch sensor. seems to be working great for me so far. the closer upstream you have the sensor, the more accurate. precat of course. If you mount it upside down (in relation to the ground) it will affect longevity as unburnt fuel or water vapors collected at the bottom of the pipe can damage the sensor. I would check your connections to the sensor first. if there is no wiring issue it could be the sensor or even the gauge.
