Air Fuel Question?
Is there a digital air fuel gauge that reads in numbers? Is there a way to get it to work because of the wrx is 5 volts and the gauage reads from 1 volt?

I have a resister wired there to stop the low cat cel. Will I still get accurate readings from it?

Do you have the resistor on B17 because you have no rear o2 sensor? Did you buy an exhaust with no cats?
If this is the case, you're S-O-L on the A/F gauge. Find one with its own wideband o2 sensor. |
