Wideband not working or is this normal?

[sschoeffler]

Just installed the wideband today and turn the ignition on did its little calibration then went all the way to red and the screen displayed ---. Started the car and the same thing, nothing changed. Now the car has open headers and its probably 4-5 inches from the end of the collector. I called AEM and they said it was normal for it to not read or read too lean to display on the AFR gauge. I just wanted to make sure that I would infact get no reading or if I should be getting a reading. Surely I am not the only one who has put a wideband in open headers.

I am not sure about the AEM gauge showing --- but 4-5" from the end of a open header is too close. You will never get a true reading, it will always get polluted by the fresh air. a quick test will be putting a piece of exhaust tubing at least 12" after the collector you should see it start reading then.
