Air fuel guage problem - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I put in an Air fuel ratio guage.  I am pretty sure I put it on the right wire but the guage does not fluctuate.  It goes from lean to rich.  My friends Turbo KAT fluctuates.  When I am making boost it goes right to rich and when at idle or driving normal is at lean.  iIt is acting like its just a switch or somehting.  He thought it was cause an SR has coil packs and his has a distributor.  Please help...

The A/F guage has nothing directly related to the distributer.  If you connected it right, it is getting signals from the Front Oxygen sensor.

Im pretty sure its not supposed to stay constant all the time. My friends GS-T did the same thing. Run lean at idle and run rich during boost. I think as long as you dont run lean during boost you'll be fine.
