This is the first outing with the RPM data logger working, and there is a glitch in the driveshaft rpm from time to time which you can easily pick out. Also, I noticed that the accelerometer unit is very sensitive to angle change, so in a wheel stand it spikes. The front went about a foot and a half up on this pass.
