If you dont feed a signal back to ecu probably going to have to "delete" the rear 02 sensor in the tune/map, by zeroing out its compensation tables and disabling associated cel codes.
If you dont need to feed the AEM wideband signal to ECU you would be better getting an extra sensor fitting installed in the exhaust for the AEM and leaving both factory sensors alone. |
So either way i need a tune for it. I guess ill just leave the aem one on and get a tune from moto east. What would be the best way to do it, if i dont need the fail safe feature?
