So I started having a problem with my Uego today.. At WOT the gauge was dropping to 10 which is the lowest the gague goes I know, but my car was still running fine, I did the Live Data with my AP 2 and at WOT I was @ 11.2 which is what I got tuned for so I know the car is running crazy rich.. I mean the gauge goes nuts at WOT it could be at lets say 14.2 and I can be in 4th gear and @ WOT the gauge just blinks and goes straight to 10.. I called AEM and they are D*cks no help at all thay just say well if it reads 10 your car is running rich F**king idiots I guess he could not understand that I had live data in front of me telling me the car wasnt running that rich..

Could this be a bad sensor?? I have had the Uego for 300 miles, I have a Helix Catted DP and the bung is near the Turbo so the sensor is probably less then 6 inches away from the Turbo could that melt the sensor this quick??

I have the same unit mounted in a Cobb DP near the turbo...I have had it for about 1500 miles with no issues. You could have a bad sensor causing this.

So you think the sensor was bad all along or it crapped out at 200miles?? I mean it was working fine till today, and the AFR's @ idle or correct its only @ WOT that the Gauge drops to 10 and gets all crazy the rest of the time the gauge is accurate when I match it up to the live data from my AP 2..

AEM said if it was a bad sensor it would read way lean not rich, and the reading would be off the whole time not only at WOT ?? So I am really

The AP is reading data off of the stock O2 which I belive is not a wideband sensor and was originally meant to read post cat readings if it was a real wideband why would anyone buy aftermarket as you could just tap the signal from stock.

The AEM is most likly reading the correct number shooting from 14.9 while crusing to 10 ish sounds about right if your mashing the gas try a partial throttle pull is it is around 12.5 if you can vary the reading with partial throttle it sounds like the gauge is working normal. Also if it is too eratic try the innovative wideband heatsink bung extender to keep the sensor from getting too hot.

Even if I dont mash the gas it goes to 10.0 after 4500rpm and higher in any gear it goes right to ten, I am tuned for 11.2 and since I got the tune the guage read 11.2 whenever I was @WOT its only been since yesterday that it started going to 10 on the gauge? I mean the guage got installed at the same time I got the tune and its never read lower then 11.2-11.1 @ WOT so for it to go to 10.0 at any gear once I am in the higher RPM's I am just confused. Cause if it was a bad sensor it wouldnt only read bad at WOT you know.. Also if I rub the inside of my exhaust its got a good amount of carbon build up so I have to be running rich..
