New to tuning myself since my tuner is no longer around.
I have a 06 IX MR and am instaling a plx wideband into the rear bung but need to turn the factory rear o2 sensor off to take it out. He had done it on my VIII i used to have but not real sure how. I have the tactrix 2.0 with ecu flash.

 

Search a bit; it's fairly easily done. You'll need a patched rom though; I'd recommend Tephra v7 instead of just the rom patched for the rear o2.

 

ya ready about it that looks like what we were using before, but i think i must really be missing something and may not be inteligent enough to make it into the threads. I can not figure out how to load it in

 

I use Tephra v7 along with another patch to disable my rear o2.

If you decide to switch to Tephra, you'll need to transfer your fuel, timing, boost and other relevant maps to the new Tephra rom. Use "Option 2 - Thanks to recompile 88590715 (v7 + Mods)" so that you have the patc to disable the rear o2 built-in.

I can check exactly how I have it done when I get home tonight if you'd like.

 

where exactly do I paste the xml to, is the current issue im having.
I may be a newb with tunning but I am better with it than the computer software part so sorry for the having issues with the simple things
thanks for the help

 

The extra xml data goes into "OpenECU\EcuFlash\rommetadata\mitsubishi\evo" then whatever romID you have. I'm using Tephra v7, so I edit "TephraMOD-88590715-v7.xml"

 

for god sakes if you dont know what you are doing at lease save a copy of your old rom.... just incase... i dint the firt time i hade to have english racing retun my car......

 

and i might need to lurn how to spell with the fat fingers......
