I have a question for all you boosted tuners....
I have done a fair amount of research on updating injector tables and its seems very straightforward. But one thing that puzzles me....
The offset and flow tables are input vs. kPa of manifold vacuum, OK, I understand that, but the tables stop at 0 vacuum (otherwise known as atmospheric pressure) but when you boost the motor you now go negative vacuum (otherwise known as boost). What does the ECM do with this injector data that stops at ZERO vacuum, does it simply extrapolate the curve as it goes into boost? Thats fine if the curve is linear like the flow curve, but the offset curves are not quite linear.
