I really need to learn XML write. I tried editing the stock rom with ecuedit and enginuity with good and bad results. I first updated to A2ZJ710J from A2ZJ500J with no issues. I reflashed the car with ecuedit after simply adjust the desired boost tables and max. wastegate duty. It gave me a cel with a P0605. something like "Internal control module read only memory". Then I tried enginuity with the same results. Apparently neither one of them have proper defs. Reflashed it with stock rom and it was fine.
Someone give a brother a hand. Please
