A/F meter

[belgiumbarry]

at idle a narrowband and a wideband will jump around, a narrowband more noticeably.

Since your gauge is narrowband it will dance alot even past idle since its range is so small.

Thats what I was trying to point out with my last post.

The PCM is constantly checking voltage coming from the O2s, if the voltage is too high or too low itll adjust fuel accordingly.. meaning youll constantly be in and out of the small range of a narrowband.

Barry, it you want just for fun.. hook up a voltmeter to the wire you connected your gauge to.. Your voltmeter will be constantly up and down, which is what the gauge is going off of.

EDIT: I use an aem eugo wideband.. prices are always coming down on these. Pretty soon they'll be pretty cheap.

does there exist a voltage "leveler".. ? :dontknow: something that passes only the average voltage ... and cut away the pieks ? that would make the A/F meter more stable ...

welwel... i connected the A/F meter to the O2 sensor .....o my god... that led circel is flashing constantly from red ( lean ) over orange ( good ) to green ( rich)... one thing i see is a bit constant red when goosing pedal and a bit constant green when pushing the pedal... wouldn't be misplaced in a dancing... ...

is this normal ? :dontknow:

either i will cut the power from it or place a sticker on it's window...
would make me crazy within a 100 miles i suppose... i placed it in the tripod above.. so it's really close to my face...

Mine does same
