talking about Nefmoto Willis. Yeah I was brand new last night looking into this lol. I've done some homework and was just asking for a guide so that I can use Nefomoto and TunerPro to change the maps in the ECU so that I can code out faults for the Secondary Air Injection. Coding out P0491.
Nefmoto works for me7 cars between 2000-2005. I don't know what kind of research you think you did but might wanna go back to the drawing board and try again. Also, unless you have a USER MADE xdf exactly for your ecu software version, tuner pro its worthless.
