I am not with the genboard presently. I cannot test what I said, but I realize already that I am probably wrong. As said above it should be a way to tune the calculus of the pulse time done from RPM and MAP, thanks to a correction in % of the MAP value used internally for this calculus . This correction being function of RPM and MAP.
However, may be this table can be used to add some low map lines at the VE table about the idle rpm, useful per ex. for the return from overrun?
