I don't think this is from shifting either, otherwise this guy is a hell of a lot faster than humanly possible given how rapid some of these spikes are. Not enough gears for the amount of spiking either.

Need more data to confirm if it is under load the entire time or not.....
What other data do you need? Would an RPM time series help?

Not sure if Torque lets me log/show two separate time series.
