I currently have the mod that ignores my rear o2 sensor. Because I have to pass MA inspection, I need to re-enable it since I put in the antifouler. I have a tactrix cable and my tune was on opensource. Does anyone know how to simply remove the rear o2 disable?

 

At least on EvoIX, you will need to find ECUPeriphery0 (FAA) and set it to 0x5D6A.

If you're stuck, in EcuFlash, go into Options and set User Level to Developer. Find out what ROM version you are by looking at ROM Info > Internal ID. Post that on here, someone should be able to help.

 

you have an evo8, so I am guessing 94170008..

if you are still running the rear02 but just have the disable mod done you can simply upgrade to my tephramod 941700015 ROM.

that will allow you to pass SMOG or whatever its called...
