Default AEM Wideband Question.

I have this gauge.

http://www.summitracing.com/parts/AVM-30-4100

Here is my issue the gauge keeps going to 10.0 after the car warms up. It stays that way the whole time. It starts at 14.7 and slowly descents to 10.0 and stays that way. I replaced the sensor and no dice. It is still doing the same thing. Is there any info you guys can give me on this?

Any help would be appreciated. Thanks.

Checked the ground everything looks good. The ground is solid, It is grounded where my other two gauges are grounded and those are working perfectly fine. Power is also good. Do you think it could be just the gauge itself? Or it's something else completely. I don't really have another gauge to test right now.

i'd double check the connectors.
if you go on aem's website, they have a forum where you should be able to get more help troubleshooting it.

Those forums are horrible. No one ever gets an answer through them.

E85 Should work with this gauge but I don't know if I have to calibrate it or just leave it alone.

Yes it will work just fine.

02 sensors read lambda, and then convert it to A/F readings. So understand that if you run E85, you still need to tune based off the GAS A/F readings.

Unless you switch it to display lambda/

I know there is a calibration dile on the back of the gauge. Should I set it to something else? Or should I leave it alone?

Anyone know about this? I am about to buy a new gauge. This is driving me up the wall. The dyno gauge does not fall below 10.0 and mine seems to stay at 10.0. The gauge is also pretty much new with a brand new sensor.

Gregrob already answered your question. You do not need to mess with the calibration. Tune the same as you would on gasoline. I run the AEM wide band as well on E85. I tune just like I would with gas.

As far as your sensor reading 10:1... I have no idea. I doubt it's the sensor its self. You may have a bad gauge.
