![]() ![]() ![]() ![]() ![]() Once you let off the throttle you are accelerating at a slower rate, or in the case of lifting completely off to shift, you are immediately decreasing your speed. You'll need to determine what rate you are accelerating at for the given speed, aero loads, gear, etc.then you have to determine how much time you lost by not accelerating for that time period. The car is just not accelerating for those 0.2s. Whether that is worth that much money to you, only your wallet knows.īryan hit it.0.2s saved in a shift is NOT 0.2s saved in a lap, in fact its much much less. 2 seconds per shift, for 10 shifts a lap, that lap will be about 2 seconds faster. That has been how it has worked for decades. Without those bells and whistles, you would lift off the throttle briefly and get really good at the of timing when you actually change gears. You'd be better served getting some one-to-one coaching from a pro driver and a data acquisition guru to show you where you can pick up speed.If you want a flat shift, then yes you need an ECU that can accommodate the strain gauges or whatever switch you run to cut power during the shift. You're only gaining 0.2s of throttle time, which is something, but not enough to merit spending that much money for a club-level car. Just because you're shifting 0.2s faster per shift doesn't mean that you actually are gaining that much time per shift. Products and services: Gearbox, powertrain, transmission, EV, hybrid, motorsport, electrification, gears, F1.Don't you need an ECU that cuts engine torque on upshift? If you don't, you'll have to use the clutch, and that doesn't do you any good when you're talking about shifting faster.Īnd you probably will only see a couple tenths per lap improvement in times.
