ok, so i had my a/f meter installed and hooked up at the ecu. the thing is that it doesn't bounce and when i turn on the lights the gauge moves to lean. i hooked it up at pin #D14. is there something wrong here or is it suppose to do that? it doesn't bounce around at all just stays in one place...but it does however move from green to yellow after the engine warms up so i'm assuming that it does somewhat work. anyone with their A/F hooked up to their ecu experience this?

 

well, mine ( it's a cyberdine digital one) reads more rich when i'm starting up, but when at normal op. temp. it jumps alot between rich and lean... like it will read one or two bars past stioch and then drop all the way lean...engine runs the same..no rpm drop or audible problems.. then then will come back up to one or 2 bars about green...., then when i'm cruising speed fluctuates right around green .. like green to a little above which is perfect...

then when i'm at WOT it should read on the rich side... and it does for a little bit but then drops to lean... ?!?! what the heck... but it still pulls... don' t notice and problems..

anyone else have input...

 

this sucks, i tried plugging it in to the O2 sensor itself and it didn't read at all! damn! i tried the white wire, nothing...green wire, nothing...and only one of the black wires worked but it was lean the whole way and even at WOT it didn't move. this sucks, i think my A/F meter may be messed up. damn thing sucks. i'm switching over to the egt.

 

It should be hooked up to the white wire, just make sure that you let the O2 sensor warm up before you can expect any readings from it. If I were you, I'd try the white wire again, wait about 15 minutes to let it idle, then drive it. If it still doesn't move then you need a new O2 sensor or you got a bad meter.

 

yeah that's what i'm gonna try to do. but why do i get readings from one of the black wires? that's what's bothering me. i get a reading right away from one of the black wires. well i'm not sure if it's really a reading but it goes to lean right when i hook the a/f meter up to the black wire. hmm....could it be that i hooked up my O2 sensor wrong? because i'm using a 99 integra O2 sensor on my 94 HB. it plugs in but i'm wondering what if after 95 Honda wired the 4 wires differently? anyone know anything about this??
