    Main spark tables with 2bar and 3bar O.S

    Is there any chance that the 2bar and 3bar O.S can have extended main spark tables? Say to 1.50g/cyl or higher? So at WOT we are not just using the 1.20 g/cyl vs. RPM range cells.

    at this time the answer is no. As a workaround you could modify the injector flow rates and VE table to give lower g/cyl values.

    I guess I'll look into that. Thanks!

    Did that on a 427 with a ProCharger F1R car recently. Works great even though it's not "technically" correct. lol

    Any chance of getting a 2 bar map based spark modifier table as part of the custom op now?
