ECU patch help.
I have an 03 evo with 94170008 rom. I have been trying to find the periphery bit patch so I can disable the emissions and a CEL for P0128 for the coolant temp. I tried to put the Tephra Version 7 on but the values seemed crazy when I opened my rom in ECU flash. Please help or give me a link. I have been searching for hours. I know this is just me missing a step or doing something stupid.
