i'm trying to figure out if i'm actually running rich or not? can somebody let me know what it should read at idle and what it suppose to read when the car is going ?

 

u cant tell ---- with them things. get a wideband
narrowband just doesnt read enough voltage to really tell u any thing

 

at idle and part throttle, it just bounces around b/c the ecu is in closed loop, so it should be sweeping from rich to lean, rich to lean, etc. when you are at wot, and the ecu goes in to close loop, that when it actually stays put, if you're turbo, you want that bitch in full rich if possible. a/f gauges suck
