Ok. When I originally hooked up my SAFC2, i accidently hooked up my Ground wires from the SAFC2 to my O2 sensor.

I corrected the problem and reground the actual ground. And hooked up my A/F guage correctly.

When the SAFC2 was attatched to the O2 sensor, I also re-ground that wire to the body. How would this effect gas mileage?

Thanks.

 

I'd guess the 02 still works and there is a way to find out. Put a meter on pin 2d if a series four and run the engine. The voltage should be between .04vdc to 1.0vdc.

 

It works. My A/F guage is working. Still trying to tune it down a little though.

Trying to make sure the A/F is working properly too.

1 bar away from the green area. So, who knows. I am at -9% across all RPM.

I wish I had a wideband and a dyno...... maybe on my next paycheck.....
