I have 2 o2 guages. One is a techno dance guage in my pillar and one is on my Apexi TT.

Why is it when I let 100% OFF the gas while in gear, my pillar guage goes complete furthest it can to red, and my apexi goes straight to 20.00 and blinks green?

and Why do they both say reverse of each other? I KNOW the pillar guage is setup for the front o2 sensor (vampired into one of the wires) and the apexi is vampired into one of the ECU o2 wires.

 

responsiveness of the gayge.


(misspelled on purpose. )

 

ok I guess that sounds like a stupid question. I guess I'm wondering why the apexi shows green and the guage shows red. kinda stupid i suppose...

 

mine does that too, my autometer a/f gauge dances then goes deep into red then doesnt show anything.

 

thats the same guage i have

 

Red on Autometer gauge means lean. 20 on Apexi means 20:1 or the max AF ratio itll show. The reason being is that you are on deceleration, and the throttle is closed. Basically both gauges are at their maximum lean reading. Sounds like they are both reading correct to me.

 

That's what I was going to say.

 

It might just be the default setting for the gauges when the AFR is out of their range.
