I use a gopro Hero. (One of the older ones that look like a cube.) I put it in the middle of the cross bar on cage hoop. It shows gages good enough to know what is going on.

It actually saved me years ago when I realized my car was losing oil pressure on launch with the wheelies. eek

As far as the LM2 that was mentioned, I have one, but IMO they are a flakey piece of junk sometimes. I have never been able to get mine to work half the time, and never did get the RPM to record. If you get a good one you are lucky. I sure wasn't.

I have been considering dropping the cash on a Racepak Sportsman.

Need to log RPM and Wheel speed to get my suspension sorted out.
