RTACS fine/coursse control

[tazinhawaii]

In the edit->properties->road runner menu, what exactly does the RTACS fine and course adjustments do? They are set at 10 and 50 now. Are these something like how far off the value has to be before the system will update the value? I've tried playing with them, and it makes a difference, but I can't figure out what difference it's making.

Thanks,
Derrick

* Fine grain: multiplier = 1-((1-PID)*(FINE/1000)))
* Coarse grain: multiplier = 1-((1-PID)*(COARSE/1000))
Where FINE and COARSE are defined in the tuning too property window and PID is the value of the RRR linked PID (i.e. BEN for the VE table) .
