I searched and found nothing other than people referencing the autometer narrow band gauge to it. I just installed the AEM uego gauge and at idle my car is running leaner than 16.5 which is the highest it reads. What is everyone else seeing at idle? Or does anyone know what it should be? Thanks, Russell.

 

I need this info, i'm having idling problems and i think i might be too lean.

 

Mine is about 10:1, measuring with my Innovative LM-1 wideband. No airpump + stock ECU = rich.

 

Do you have any problems at idle? I also read that i should disengauge my Airpump. I was wondering why i got really high readings, so i will try this.

 

I just used my S-AFC and kept pulling it out until it almost died, then I added 5%. At idle the motor isn't underload and you don't have to worry about detenation(to an extent) so I figured I'd take out as much as possible.

 

Yup, your smog pump is throwning off your readings. Unplug it while tuning. Start around 12.5, lean it out a little bit at a time and see what your car likes.

 

It would be nice if i knew how to adjust the A/F on the PFC using the commander. Do you know how?

 

11.5:1 for me
