aem wideband

[marc3]

my buddy is using a aem wideband in his supra, there are different settings,that you can use , by turning a littlte screw in the back.
which should he use?
and when tuning hi throttle with a safc1, what should the reading be on the wideband gauge?
thanks

1. you should consult AEM for what each settings mean.

2. what AFR you tune to is really up to you. on pump gas, i wouldn't recommend going much past 12.0:1

11.8afr is usually a good number. I have the same wideband and i would also like to know what the screw on the back is for.

so did it not come with any documentation?

[drjonez]

2 seconds on AEM's support forums yielded this.

you'll be especially interested in pages 9+....
