Just learning this software. Ive been getting the p1235 code as well, where do I paste these codes from tephra into my xml? Then is it done? or do I need to actually go into the tune and turn them off there? thanks for the help

you can paste the xml snippet anywhere inside of the matching .xml file as long as you dont nest one tag inside of another. it is best practice to keep the DTC section grouped together.

the xml file is typically located in C:\Program Files\OpenECU\EcuFlashBeta\rommetadata\mitsubishi\ evo\

and yes, after you paste the snippet to your XML file and save, you have to open ECUFlash to change the values.

the xml file is just a list of addresses needed by ECUFlash to read your rom. you actually have to change values through ECUFlash.

and remember, always check to see if the before values match.

Is there no way to disable the P0420 catalyst efficiency code on a 2008 without taking out the rear O2 sensor, disabling the heater, and disabling all of the other codes that go along with that?

Just saw disabling the 0139 takes care of 0420 on the 2010+ years but does it work on 2008 too?

On a 2008, disable these:

DTC P0139
DTC P0140

And set the Rear O2 bit to 0 in the ECU Options Set #2 bit.1.

That's it. No need to remove sensors.

Doesn't the ECU Options #2 disable the heater though? If the sensor is still in the exhaust with no heater it will be destroyed

Golden

Yes.

So you basically told me to destroy my rear o2 sensor two posts up?

Any chance of disabling P0247 on 5268xxxx ROM? Please help.

Golden

Yep. If you read this thread from the start, it has you do it years ago.

Anyone willing to help?

I just looked at Golden's definitions. It's defined for this ROM set.
