For those of you with the Aem wideband,How much fluctuation do you get at wide open throttle?Mine will jump from 11.0 to 12.0 and all points in between at Wot.I called Aem and they said to run the ground directly to the battery,well I done that and it didnt help.So basically I have a $280 lightshow.I have heard about leaks on the bung install.Does anyone have input on this issue??

 

Mine only varies a few tenths at WOT. Where did you install the sensor?

 

before the cats drivers side,close to the factory o2 unit.

 

That is where mine is too. Sounds like you might have a bad sensor.

 

mine varies very lil maybe a couple tenths at wot. still cant get livelink to show same thing as aem guage does though.

 

I have Innovate Motorsport Wideband A/F and I get on WOT 10.8 and has jumped up too 15.8 on cruisin around.

 

Maybe there's something wrong with your tune???

 

Do all companys that have electrical issues with there products give you that same response? Run the ground direct, has it ever fixed any electrical issues with an added component?, It's been my experiance to only increase my labor time, ugly the engine bay a bit and provide no measurable results, I understand to theory of direct ground but if they don't list it as a must in the install book why when you call is that on the top three on there canned responses?
