Smooth Throttle for UpRev

wstar · 09-29-2013, 06:51 AM

I don't think I posted this here before, only off in another thread, but this is what I mean. This is a scan from the excellent book "Think Fast" that covers a lot of race car setup stuff. They're making the case that it's better for the curve to go in the opposite direction of the one in my throttle table. Either way you want the start and end points the same, so the curvature of the graph is all about trading off fine control in one area for lack of fine control (rapid response to input) in another, and the argument is basically that you want more fine control in the low end of the pedal since that's where you're feathering around with traction in mid-corner:

Well, with that in mind, are you interested in developing a table with that curve?

I could help with testing.

I will someday. Setting up the software to do it as a one-off and doing all the street testing of the map is a time consuming PITA, and I've just got bigger things to worry about right now than fine-tuning the throttle (like, wiring up my new dash/steering controls and getting the cage-related stuff done). Maybe in November when all that settles down.
