Battery Voltage
12 volt event
Record Button
What information would you gain from these inputs? Wheel slip, acceleration rate, missed shift RPM?
What else would need to be added to that system when used on a carbureted stocker?

You can see what is happening before, during and after a gear change.
You can see what your torque convertor slippage is as the car goes down the strip.
For similar weather conditions you can overlap Accelerometer / G-Meter data and see where in the run a change helped or hurt.
Engine acceleration rate will vary not only for from one gear to another but also within each gear. One reason I like an inertia dyno fixed load variable acceleration rate engine test.
