Can I added wheel speed sensor reading to my log?

I would like to use ABS wheel speed sensors as a way to see tire tire slip on launch.

. Guess it depends if that info is provided by your ECM. I have a scanner setup plotting the difference between front wheel speed and rear wheel speed to track what's going on at launch. Yet to try it, but should work

Should be a driven wheel speed and undriven wheel speed you can use for this.. in theory anyways. Depends on the vehicle but look for that

i was using the driven and undriven speeds the other day and it is good to watch wheel spin, since my front to rear are staggered wheels/tyres there is a 0.5-1km constant difference in the reading, then anymore then that is spin, it actually amazed me how much the rears do spin compared to fronts

Could probably do a math parameter subtracting the two and factoring in any difference you normally see then graph or chart that, if you aren't already

Using ([8006.56] * 1.1) - [8005.56] where my rear tires are 10% taller than the fronts.
It's interesting to see how the RPM difference between front/rear go from +10 RPM difference on hard accells to -10 PRM difference on heavy decells. Has to be a change in diameter as the car squats then then front pushes down.

That's pretty neat, I'll have to play around with it some time

hopeing the Outputs get working soon cause I wanted this to trigger a light when I'm spinning past a certain point. Fun Factor.

You and me both. I want to use that output to take some spark out.
Would be super cool to get a frequency output proportional to the result of a Math function.

Thanks for all the feedback. :-) Very appreciated.
