$88 Rpm derivative spark control. What it's it?

[RobertISaar]

to change the amount of advance that is being added or pulled, you'll need to change the D-RPM multiplier for the gear you're in(effects both added and pulled spark), or change the maximum RDSC spark value for the gear you're in(D-RPM is Negative, to change only pulled spark).

thanks robert!
i had them set to 0*. i thought it would pull 0* timing out, not set to 0* on neg drpm! i found some 3.1 numbers from an auru bin and they work much better. ill play with it some more.
