Hey... i was going to tap my air fuel ratio guage in to my o2 sensor. But i accidently fucked that up (dont ask) so know im going to run it in to my ECU instead. With my o2 sensor having a cut wire will my ECU hooked up Air fuel ratio guage still be accurate?

 

Why don't you just solder it back together and put some heatshrink tubing on it?

 

My A/F gauge is tapped at the ECU.. ..If the voltage that far away from the source is OK for the ECU, it'll be OK for your A/F gauge.

 

mine is at the ECU too, but your neither your gauge nor your ecu will work correctly if you have a cut wire still, just connect it back up and do it from the ECU

 

Its a real bitch to get at... dont work on your car drunk!!

Im gonna fix it its just a bitch and im so far along. I just didnt want to deal with it. Im going to fix it

 

don't even worry about it anyway, the guage isn't very accurate in the first place.

 

whats a good guage to have to make sure i dont run lean?

 

It's not the gauge that is your limitation. It's your O2's technology. It wasn't created to gauge exotic A/F ratios. It was designed to gauge stoich (14.7:1). The voltage curve for a single wire O2 is about 0.92v ~14.2:1, to 0.05v ~15.2:1, that's it.

You will need a wideband O2 w/ controller to get more accuracy, and greater spectrum.

 

That isn't the biggest issue, the ECU needs the signal. Are you throwing a CEL? I would think if you messed it up your car would be in limp mode. You should fix it so your ecu is happy, then worry about monitoring it.

 

i fixed it
