I had spare time to do some measurements.
I think they may be unreliable. Currently, my Dump pack is out of the car and the batteries are getting tested. While I am able to test the signal voltage, the ESC spins a little while powered only by the 12V power suppy. I am unable to test drive to log full boost. I need to test drive because I found an unexpected result (The second result). The procede map I loaded (SOJHINNrev2) that I thought had full boost, did not have full signal voltage. Unfortunately, at the time I drove it and had full boost, I did not measure the voltage signal. I have loaded other maps since. I need to test drive to confirm what boost it produced with the current loaded map.

The measurements were done while the car engine was off. To ensure a full signal, I had the laptop connected to the Procede and depressed the accelerator fully. I entered 100 (full boost) in the cell that corresponded. Yes, the rpm was zero. I don't know if zero rpm effects the procede signal.

Measured voltage signal to ESC control box.
5.21V --- Full throttle switch (not using procede)
4.05V --- SOJHINNrev2 uncalibrated (default) throttle input 0-1023
4.03V --- SOJHINNrev2 calibrated throttle input 156-833
3.94V --- SOJHINNrev2 manually entered throttle input 156-1023
3.96V --- SOJHINNrev2 manually entered throttle input 156-818

As I said, I need to test drive to test the difference in boost between the throttle switch and procede map. I can do this on the fly by flicking a switch and it clearly shows any difference in maximum boost.
Also, while the car was stationary, it was very awkward to do these measurements with a voltmeter in the footwell of the car, sharing the space with a laptop. I don't want to wire up a method to measure signal voltage while driving

Hopefully next week I will have the dump pack sorted and may be motivated to try further...
