AEM UEGO weird behaviour

postby GeorgeG5 » 04/20/14 @ 10:22

so, I finished the WB instalation today and it acts kinda weird...

values are all over the place (stock engine, stock ecu, intake and exhaust manifold) and when I get off the gas, it falls down and than shoots up and goes beyond 18.0 and shows just the lines...

anyone has any insight?

What's it wired up to?

engine fuse under the dash... but I've tried two other fuses and it did the same thing

Assuming you checked connection for the sensor already, you bought it brand new ya?

Anything else plugged into that engine fuse or no... Where is your ground going to

some nut close to the fuse box... I've checked it with the ground points and it's good

If you got a good ground and power supply, do you know how to check the sensor?

friend told me it's completely normal... don't know, maybe I'm just too sensitive and was expecting something a bit different lol

I had to ground mine away from the ECU to make it work right. I used a ground point on the PPF. Took me months to figure this out.

Also an AEM UEGO.
