I have the AEM EMS 30-1130 installed on 7mgte with AEM PRO version 3.23.9.189. I set up the throttle and timing. I have added that I am using a AEM 3.5 bar manifold pressure sensor and RC 550 3ohm injectors. You can see my other mods in my signature. I have removed the MAF since I installed the pressure sensor.

The car starts fine. All the sensors seem to be working, except the O2 sensor. The AEM AFR reading is stuck at 14.7. This is for warm and cold idleing. My standalone wideband reads idleing at 10.5AFR. Any hints for the next step?

I have a feeling this isn't a situation were i need start making fuel adjustments just yet.

I atl east want it to be drivable to the dyno.
