It cuts the spark when there is more than 80% throttle poition, and the clutch is kicked. Then there are two options, you either set a millisecond delay, or leave it as automatic to reengauge the spark. > > Concept is that the spark cut to all cyclinders make the motor produce no torque therefore allowing the syncros to slow right down and let you band the next gear without being locked out, or in my shitty o2j VW transmissions case, grinding the piss out of the shift. > > also the motor doesnt go into vac. so you dont loose boost. > > The delay is the best way to set it up, but you need to be on your game. Set it to a 250ms delay and you have just enough time to kick the clutch hit the gear and the spark will be back on at the end of the delay. The automatic setting works off the clutch micro switch and has a slower spark reengaugement. > > As long as your shit is set up right and can hold the power your making, this is actually easier on your shift hubs and syncros. with the evo’s, tephra ( stock ecu mastermind) came out a patch for NLTS (no lift to shift)… pretty neat with the stock ecu… --- _[View the full topic](https://forums.speedlife.net/t/is-it-bad-power-shifting/248959)._
