Datalogging with UpRev is one thing, but we need to acquire signals at the source (I/O control signals and driver output). The ECU and VVEL module output signals to control the throttle and VVEL actuators and each has its own position sensor, but I don't know the system well enough to determine if the control signal output to the actuator goes from A to B in X milliseconds that the actuator is expected to physically change positions from A to B in X milliseconds as well.

In other words, we might have a situation where the control signal expects the actuator to move from point A to B. The actuator does move from point A to B, but there is no mention about how fast it should get there to meet the timing tolerance. It is like playing an FPS game with a wireless keyboard and mouse getting pwned from the 0.5s lag.
