Let's say I have the O2 feedback enabled on the EMS. The UEGO wideband is wired into O2 input #1. The OEM secondary O2 sensor is hooked up into the O2 input #2 but the O2 sensor is not physically in the cat.

When feedback is enabled does the EMS take readings from both O2's or just the primary? The OEM one is reading fresh air wrapped up in foil.

Any help would be greatly appreciated.

 

i think you can set it to which ever O2 you want it to read from. i'll have to double check by logging on to EMS tomorrow.

 

o2 FB only goes off of o2#1(primary), well thats for Hondas at least. i dont think u can change that. well, at least i looked through mine, i have a 30-1010 box, and i see no option for that.
