Im sure if you could put on a front and rear wheel speed sensor you could set it for turning on a limiter if there is a wheel speed differential over X amount.
Dan, I also purchased a Megasquirt 3 kit just before the holidays as a winter project. I got the kit built in a day and took another day to interface it with a junk yard ECM to use as the connector board. I also installed peak and hold injector drivers on the cut up ECM. I'm running the MS3 in full sequential mode, two MAP sensors, cam sensor and knock circuit.
Getting the startup and acceleration enrichments close to correct took a little time due to the 75pph injectors. I am also snow bound, and cold, so I have not had a chance to drive the car on the street yet. The engine starts in 25 degree weather just as well as a stocker. From all indications it seems like the MS3 will manage the engine just fine.
I plan to wire up the COP outputs later this year.
That would be something that can be programmed into the TC module or sub routine. Front wheels see so many pulses per revolution, rear wheels see so many pulses/rev during normal straight line driving.That might work fine for street driving, but I am skeptical of how well it would work on a drag car that can pull the wheels. I suppose, having diferent size tires could be worked around.
A timer can be programmed off the transbrake to ignore the first 1.xx seconds of the run.
Or, a certain acceptable amount of slip can be programmed for that same time period. That way, you could program in when in the run you want the front tires to touch back down.
