No offense back, but you need to learn how tuning software should work. Changing the fuel/air ratio to optimal during acceleration has no effect on driving fuel tables with other software I've used like LT1.edit and HP Tuner. Your tweaking apples and oranges. The computer is suppose to be looking for certain air/fuel ratios and correcting itself to them. Obviously this is not working correctly with the AccessPort.
