I just recently hooked up my aem wideband on my 99 si.......the 10th of a degree for example.......12.3only shows 12.

Just wondering if anyone had any suggestions......the back light for the number drops out after driving the car for a while......didn't know if i was losing voltage or just a mechanical problem with the gague and need to send it back.......need some help asap though........really need it in there...

 

I would send it back then.. I have the AEM UEGO and it works perfectly..

 

Check your ground. Must be directly off the negative terminal of the battery. If it already is call up AEM for a RGA# and send the gauge in.

 

if its not grounded to the battery will it fade out? i'm putting it up to batter right now.

 

got it fixed.....it just had a crappy ground....
