Default Anyone have a 3 Bar Racing Dawes Device/EWS Air/Fuel Meter?

I purchased a car withone and the previous owner said it never worked right.....So I downloaded the instructions and started tracing wires....He has the signal wire correctly connected to the 02 signal wire and the ground directly to the battery...and the hot lead was disconnected....So I hooked up the hot lead but really no difference...

The main light that comes on most of the time during non to mild boost is the red (lean) light and very rarely the yellow(stoch)....During full boost no lights at all.... I have not seen blue or green in the 6 months I have had the car...

Anybody other have one? played with one?

Thanx

sensor needs to be calibrated, or is this just a simple Afr gauge that uses the narrowband signal to give a rough idea of where you are at? If thats what it is i bet you are just a little rich all the time because of your fuel mods.

Oh i just noticed you have "Falcon" tires ... thats baddass lol. I went with the Falkens myself.
