when programing the box to memorize WOT voltage, if when i push the pedal down but not to the floor does that mean that when i'm using the system and push the pedal pass that memorized point it stops spraying?

 

It will program the Zex box to WOT wherever you hold the pedal down for the 10 seconds. It is not a good idea to set it to partial throttle though, if that's what you're asking. There is no reason to spray at partial throttle.
