This unique system enable's full or partial throttle clutchless up gearshifts and clutchless downshifts!!! it will blip the throttle exactly the right amount at exactly the right time when changing down the gear's (patented) please go to [URL=http://www.quickshifters.com] for full details including. system below and on-board footage
ELECTRIC GEAR SHIFT SYSTEM.using buttons or paddles
PADDLES FOR ANY GEAR SHIFT SYSTEM.
3 x DIFFERENT CLUTCH LESS GEARSHIFT SYSTEM'S. MANY SYSTEMS NOW SUPPLIED TO FSAE TEAMS ARE YOU AS SERIOUS AS THEM ABOUT WINNING !!!
OR PLEASE PHONE UK +44 01206 322557
CELL 07970 461824FSAE (rule B8.5.2 "The throttle must be actuated mechanically, i.e. via a cable or a rod system. The use of electronic throttle control (ETC) or “drive-by-wire” is prohibited.").
1 Our system does not use any sort of electronic throttle control
2 The throttle cable or linkage remains exactly as original on the car/engine no changes at all.
3 we have supplied these systems to fsae teams for the past 3 years with no problems at all
Cheaper version also available clutchless up gearshifts only

We are curious about using your system, but we need to know exactly how the throttle blip is actuated?

Flatshifter clutchless downshift system ( Autoblip )
The Flatshifter Auto Throttle Blip downshifter employs a patented system which powers and automatically regulates downshifting using engine vacuum.
The operation of the system is based on the principle that engine inlet manifold vacuum is approximately proportional to engine load when a vehicle is coasting with the throttle closed.
The throttle blip control box houses a valve which, when triggered by the main control box, feeds a timed and regulated pulse of engine vacuum to the throttle blipper which in turn blips the throttle by a controlled amount depending on engine load and rpm.
This gives seamless automatic control downshifts at all speeds with only one variable adjuster which varies the level of blip to suit the drivers preference from aggressive to passive downshifting and everything inbetween.
The system has a built-in maximum blip limit to prevent over-revving when downshifts are made too quickly by inhibiting gearlever movement until the engine rpm has fallen to a safe level for the next downshift.
Installation is simple as the shifter does not require a gear position indicator or engine and wheel speed sensors or even a computer to set everything up . The throttle blipper replaces either the idle control screw or the redundant closing throttle cable on fly-by-wire engines.
This downshifter is uncomplicated, compact, light weight, and because it is powered by engine vacuum it is very fast with the capability of up to four downshifts per second.
The system is incorporated into the Flatshifter Expert and Pro shifter kits or can be supplied for downshift-only as the Flatshifter “Blip”kit.
Flatshifter concentrate on your driving not on adjustments
Full throttle clutchless up shifts & soft restore feature.
The Flatshifter up-shifting control box function employs a unique ignition or fuel interruption system featuring soft restore.
The soft-restore feature is a user-friendly method of providing the optimum upshift kill-time without having the complexity of having individual kill-times for each gear.
Individual kill-times for each gear may be suitable for race applications were close ratio gearshifts are made within a narrow power band and smooth shifts are not important throughout the rev range.
Soft-restore gives smooth upshifts at all revs and speeds with close or wide ratio gearboxes. This is achieved with shift control software that unloads the gearbox by cutting ignition or fuel supply voltage abruptly and then smoothly and progressively restoring the power simulating progressive throttle opening. This allows a kill-time window to suit all gear ratios without the penalty of transmission shock loads caused by long kill-times required for lower gears which cause transmission damage and loss of traction.
This is achieved by rapidly unloading and disengaging the gearbox driving dogs and then progressively speeding the dogs up as they engage the next gear. This system prevents the dogs baulking when they are both rotating at the same speed.
Soft-restore gives smooth gearshifts at all revs and speeds with close or wide ratio gearboxes. This is achieved with shift control software that unloads the gearbox by cutting ignition or fuel supply voltage abruptly and then smoothly and progressively restoring the power simulating progressive throttle opening. This allows a kill-time window to suit all gear ratios without the penalty of transmission shock loads caused by long kill-times required for lower gears.
This means that the gearbox driving dogs are rapidly unloaded and then progressively speeded up to synchronize with the dogs of the next gear so reducing shock loads to the transmission and drive train.
When changing down the box the gearbox dogs are also meshed but on the opposite faces. This is due to the compression of the engine acting as a brake. Precisely blipping the throttle by the correct amount at the correct time provides a brief window when the gears are unloaded and the shift can take place.. The ignition or fuel interrupt is of no use in this situation as killing the engine will make the engine braking even more severe and mesh the gears even more firmly. This is why a throttle blip is required for downshifting which means that both up and downshifts can be made clutchless (The clutch is still required when selecting 1st gear & pulling away).
Some of the Advantages of using the Flatshifter quickshifter system.
1 Full or part throttle clutchless up gearshifts &
2 Clutchless downshifts (patented system)
3 Gives engine braking on downshifts.
4 Allows more time to concentrate on lines & braking points.
5 Built in inhibitor to protect engine from over revving on downshifts.
6 Less gearbox and clutch wear.
7 Faster more consistent lap times.
8 Allows deeper braking into corners with left foot braking (cars)
9 Suits most motorcycles & all bike-engined vehicles race or road, and all sequential transmissions .

Mmmmm,
Pity the throttle blipper makes it unacceptable for FSAE/FS use.
