Automatically adjusts pump uptime based on desired velocity (X) using Proportion data only
hook green wire from main hub (read Velocity (V) and location data) to the constant combinator
hook red wire from light to fuel pumps (pumps on if check mark = 1)
works best when uptime is under 50%
for 10+ thrusters or highers speeds, use two pumps side by side
