i understand how heui works as far as icp pressure, duty cycle, and injector pulsewidth. the other stuff such as timing and fuel, not so much.
Does the software come with basic performance/econo/tow tunes that can be tweaked? or is a blank set-up?
what about shifting also?
am i even asking these questions in the right section of the forums?
