I got my throttle delay today. This is the second prototype if you can call it that. The delay can be tuned from 1-10 seconds. Rise time is slow and drop time is fast. This should help with my high power sensorless setup cutting out when running on the 100% speed setting.
All that is needed from the end user, is too install a 1k ohm resistor on the signal wire and tap into the positive and negative throttle wires. As you can see, the module is really compact.
