MY wide band reads around 15:1 at idle. I think this is normal. Crusing any where from 14.0 to 15.0. Under boost I stay around 14.0 - 15.0 initially, then after almost 2 seconds I go to 11s where I belong. Im using AEM with a bosch sensor, and its located 30" from my exhaust turbine (didnt wanna buy new sensors all the time) Decelerating it goes full lean. Is this normal? Sorry for such a noob question I know ima tool, that my green 7m is pretty wack, and I dont even drive a supra so those comments arent necessary. :dunno:

Yes, on deceleration it'll go full lean. At idle after the car has warmed up for about 5mins, I stay at 14.6-14.7 And at cruising, also the same.

yes, most of the behavior is normal.

you may want to check your TPS settings... waiting 2 secs before dropping to 11s may or may not be harmful depending on where you are in the RPM/boost map.

you can even cruise a little leaner if you wanted...
