My car isn't super fast and it generally hooks just fine, but driveshaft data has been interesting to see. I just went from an 8 trigger wheel to a 16 tooth trigger wheel on the driveshaft so it should give good data from the second it moves even the smallest amount. I also recently added a front wheel speed sensor. I don't have a particular need for that data but I had an extra sensor, and I had an available input on my Megasquirt so I wired it up. This will allow me to see % of wheels slip and use traction control in the future if I choose.

I want to add an G meter next. There is lots of cheap options for those, I expect to be able to have it up and running for $50-75 because there is no special proprietary sensors for my application.

I have seen others post this, the problem with good data is you will just want more and more. That appears to be true in my case lol.
