OK I'm on the right track now. I unplugged from the car and went inside and opened everything with tuner pro. Now I edit my .bin. for the Hitachi maf I changed krkte(I'm pretty sure that is the file its not in front of me any more) from 0 to 1027. And I'm going to start with fueling when I get out of work. One question I still have in tuner pro files or maps have two different icons. The square ones and the pie3.14 looking ones. Can you tell me the difference?
