Hi,
Could , in the future, be possibe to impliment a ignition based launch control mechanism? Using lots of Retard to reduce engine power when wheel spin is detected.?
I'm not sure what sort of sensing equip would be needed to detect wheel spin, I guess it would need sensors on front & back wheels to determine a differential speed / amount of spin.
Would this be a practical implimentation.?

ok, from the description you
ok, from the description you want traction control, on all other Megasquirt & Megaother units, it's only a switch that you activate manually when leaving from the line.
Traction control could be added if a car already has ABS so then you can use the signal from the different wheels.. But in order to have a system that is worth using, you need to be able to modulate each wheel, and that is usually done with ABS, else when a wheel spins, you cut power everywhere, that you can do with brake pedal or clutch pedal.

Another (crude) way of some sort of launch control is to retard the ignition if the rpm is going up too fast (when wheelspin occurs). More of a launch control then traction control.
For this you would need a rpm/s value and possibly a number of degrees you want to retard when your rpm/s is getting above this. This rpm/s value will depend on track conditions/tires etc. and can be determined by trial and error.
Any comments?
