Aem WB02 readings.

[EclipticalGS]

Ive just installed an Aem Eugo wideband...

Well, the install went smooth, good power source and ground.

I made sure the calibration dial was set on Gasoline which equals 14.6 stoich or some crap for gasoline. Well, I ran the car, it sat at 14.5 at idle fully warmed up, I revved the car and then after throttle plate closed the afr's would jump sometimes off the gauge, lean, like over 17:1 ....which i assumed is fine.

Well, I felt manly with this 16G, and turned up the boost to about 17 psi. I did a second gear romp, and it went from 14's afr range, and went down to a steady 10.6 WOT while holding the 17 psi, almost through the whole gear.

Does that sound normal? While driving ive never seen the gauge go above 14.6 unless letting off the gas.

Also what are these calibrations?? Is it just 14.6 for gasoline gets multiplied with the 02 voltage and creates a afr? like .99 02 voltage would be 14.6 afr, and a .70 voltage would be 10.3 afr. Or is that <<<< what a narrowband gauge does.

Just wondering if my car sounds still stock tune.

boost 25 psi
Idle should be around 14.4 to 15.0
Cruising should be 14.7 to 13.0
Safe WOT should be around 10.0 to 11.2

so im running fine then. cool man thanks. Ill assume that when i let off the gas and the afr's jump up to 17-18 thats just the injectors shutting off, and leaning out.
