Wideband ?

larrym · 10-07-2008, 06:23 PM

I just installed an AEM wideband and gauge, I'm struggling with the tune. I got things set up as per usual specs fuel pressure was at 42lbs vacuum off. Preset settings on my translator (0 no change for wide open throttle and 9 on the base settings no change) and chip is as it came I even unplugged the ecu lead to reset it.
Idle cruising and light throttle all show around 14.5 as soon as the boost starts to come on the wide band reads around 10.0 and when I get to about 5lbs of boost I get knock readings on the scan tool. It pulls good but I don't want to hurt it.
I tried pulling 8% of the fuel off the chip no change.
Cranked back the fuel on the regulator no change.
Narrow band on the scan tool reads 890 or so when its boosting.
Block learn and Integrator all seem about right too

Sounds way rich....you don't say how much boost you are running, what timing, and if you are using pump gas, alky, or what....

It is rich no matter what, however.
