Having some problems with my Wideband readings. Idle is between 14.6 and 15.3. WOT 12.2. Is 12.2 ok? And also it jumps all over when I'm not idle or on it. Just cursing it's bouncing all over. Any help?

 

Posted this in the wrong area. how do i move/delete?

 

Your readings sound normal it should move around as the ECU is trying to keep it as close to 14.7 and it should move back and forth. Now when you go WOT thats when you should see it get lower/ richer, for me 12.2 seems a little lean for WOT unless your running e85 or other type of race fuel. I think somewhere between 11.0-11.8 would be safer, but then again what ever your engines happy with when you get it tuned.

 

What kind of wideband?

I just installed my AEM about a month ago and those sound normal to me. Mine bounces from 14.7 to 15.3 during idle and cruise.

Like the above poster said though, on pump gas WOT should be high 11's. I would check with your tuner

 

I'm having it tuned tomorrow. Thanks.
