Notes from another thread
Good stuff I thought I'd paste here for future reference.
HighPSI - 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.
DonWG - 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.
Or, front wheel sees so many pulses/rev, driveshaft sees so many pulses/rev during normal straight line driving.
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.
HighPSI - Based on my experience with traction control, that won't work very well. Gary Harmon's TSL car get's around one wheel rotation in the 60' where the traction control is most needed. Since they launch softer, the DR cars do get a little more front wheel speed, but nothing that is consistant enough to calculate off of. I personally would consider using another method than comparing wheel speeds.
DonWG - What if front wheel speed was ignored for a time during the launch and only driveshaft acceleration rate was looked at? Then once a certain front wheel speed was seen, then it would convert to front wheel speed vs. rear wheel speed, or driveshaft speed?
If we're going to continue this TC line of thought, how 'bout we move it to the TC thread?
