Trying to figure just exactly what the "pump" setting does in the setup?
It's in the differential setting so I can only assume it's related.

Re: Setup question
I have no idea Rick. Like most of things in setup, i don't really know what it does, i just play with it and see if laptimes get down, or if the car feels better.
Sorry

Re: Setup question
Pump is the total Diff characteristic (0 = Open, 100 = Welded). Power and Coast are then sub-refinements, and Preload is a threshold.
So basically now the summary as I understand it: If the Diff is "welded" then both rear tires spin out at the same time, if the Diff is "open" then the unloaded tire spins much earlier, the loaded tire gets a smaller share of engine power (and thus keeps traction, but at reduced acceleration. Find a setting with some manageable oversteer (slow onset of both wheels spinning).
