I use a programmed curve as I have a crank trigger - for starting it starts at 25 then it goes all in at 32 at 1200 RPM - I also use a curve at the top end to slow it down for the index - when it hits third gear it pulls the timing back over a prescribed time - works great at scrubbing 2 tenths !

If I wanted to get creative I could use it for traction control off the launch - but I have not yet..........
