SO WHAT DOES THE EXPERT BUMP & BLIP SYSTEM DO?

It’s a pro-shifting device that temporarily cuts the fuel or ignition spark to the engine which unloads the gearbox allowing you to shift gears when up-shifting without coming off the throttle or using the clutch at any engine speed, this reduces the gear shift time, making you much quicker on the track. This unique pro-shift bump & blip, the system also enables clutch-less downshifts (up to 4 in 1 second!!)

Although the obvious advantage of a seamless gearbox is time saved during acceleration, the shorter, smoother shifts also make the vehicle much more stable – especially beneficial when accelerating out of corners.

When driving a race/ kit car with a sequential gearbox, it will only take you a very short time to realise that the slowest part of changing gears is the driver! Up-shifts without using the clutch is do-able with practice but difficult to get right each & every time, but once you really start trying to push the speed of the shifts, most people find it’s very difficult to get the timing of lifting the throttle, changing gear and reapplying the throttle at just the right time. If you don’t lift off the throttle enough, the gearbox dogs won`t unlock and the gearbox will not shift, or lift too much and for too long and the car will start engine braking, and once again the gearbox dogs lock and then, shift will not happen.

REMEMBER THE SLOWEST PART OF GEAR-SHIFTING IS THE DRIVER!

“Graham,
I have fitted the Flatshifter Expert & paddle shift kit to my off-road racing buggy, I find it very precise and reliable when racing, in my last 5 events I finished with 4 wins and a second and the second was my own fault as I was leading all day and I changed my tyres and forgot to check the tyre pressures. I find that I can concentrate more on my driving as I don’t have to lift my hands off the steering wheel at any stage when I am racing and I can go down 3-4 gears in less than a second so I can leave my braking to the last second.”

ADVANTAGES OF USING THE “FLATSHIFTER EXPERT BUMP & BLIP” QUICK-SHIFTER SYSTEM

---

Lap Times:

You can expect a distance gain of at least 1 meter per full throttle up-shift. For example, 15 gear shifts per lap over a 20-lap race will add up to quite a substantial advantage over your competitors or time sheets. clutch-less downshifts up to 4 in 1-second lead to shorter braking distances, and you keep two hands on the steering wheel, enabling reduced lap times.

The soft-restore feature is a totally unique user-friendly method of providing the optimum up-shift kill-time without having the complexity or necessity or added expense of having individual kill-times for each gear, Soft-restore gives smooth up-shifts at all revs and speeds with close or wide ratio gearboxes. This is achieved with our unique 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.

Max kit & Expert kit – the ultimate combination

Ian Catts superb new car using Expert Max & paddles

Clutch-less downshifts

Left foot brake instead of using the clutch keeps your suspension level through corners for faster corner exit

Longer clutch & chain life & Transmission

from much smoother shifting ie not keep coming on /of the throttle and clutch

Improved Concentration

With fewer things to think about while driving it enables you to concentrate more on lines, braking points, your competitors, etc. which give quicker lap times. Paddles allow gear changes to be made quickly with less effort. With full throttle clutch-less shifts both hands are kept on the wheel, eyes concentrating on the road ahead.

Smoother less jerky shifts with less chance of unsettling your car ie breaking traction when cornering in wet and dry conditions.

Gearbox clutch-less downshifts are now possible !!!! see the video Lotus Elise GT Widebody – Honda iVTEC K24 / Blip-shift Test below.

Flatshifter had been producing the highly acclaimed and unique Flatshifter Pro system (The Ultimate Race Quickshifter System) for many years ,when we were contacted by one of the world’s largest and well known Italian race suit and motorsport accessories & race car designers/ manufacturers to design and manufacture a race-specific sequential shifter kit version of the Flatshifter Pro system.

---

After many weeks of track testing and liaising with the professional F3 race drivers the final setup and specification of the Expert quick-shifter/ sequential shifter kit was devised and raced with amazing results. See the feedback page for some of the lap record-breaking championship-winning videos and customer feedback letters.
The Flatshifter Expert sequential shifter kit provides all of the ease of use of the Flatshifter Pro for effortless full or part throttle clutch-less up-shifts and auto self-regulating throttle-blipped downshifts without using the clutch, but with extra refinements to give the serious racer the fine-tuning and precision required to get the maximum out of his machine
The Flatshifter Expert does not require individual gear kill times the system’s soft-restore feature is a totally unique user-friendly method of providing the optimum up-shift kill-time for each gear without having the complexity of using a laptop computer and all the trial and error involved in setting up individual kill-times as with inferior outdated sequential quick-shifter systems.
Race Bike with a Quickshifter (Flatshifter Expert system)
Soft-restore gives smooth up-shifts 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. There is also far less chance of breaking traction when shifting mid-corner or on wet & slippery corners not forgetting far less chance of mechanical failure and wear, the best quick-shifter kit bar none.
Flatshifter kits are available for just about every brand and model of motorcycle engines  & most other sequentially equipped race cars, including those fitted with: Carburettors,  Slide carburettors, Jenvey  & radical throttle bodies, fuel injection, turbocharged & supercharged engines, and can cut the ignition or fuel injection, in fact, you name it we can probably do it !!!

EXPERT SYSTEM CUSTOMER COMMENTS

“I’ve had a look at some of my data and, on my 1585cc Pro-sport, the acceleration curve is smoother with the Flatshifter than with totally manual up-shifts (I am naturally a pretty rapid gear changer and in my old K engined Catering van with a 9.5k rpm soft cut and an H shift, most spectators believed that I had a bike engine and sequential ‘box) and saves around 0.4 secs over 2 x 250 m flat out acceleration zones. But, the real-time savings come under braking. With the Flatshifter I was able to stay on full-throttle, with no cruise period, concentrate my right foot on a total “doom” brake into the bend, only having to modulate braking effort to avoid locking and maintain Tyre loading (see Milliken and Milliken’s “Race Car Dynamics” if you want to explore the theory further).”

LCM

“Graham,
What is clear is that by allowing me to concentrate on the braking going into a bend and staying flat on the throttle while up-shifting, I gained 1.0 secs per 30 secs of the average sprint or hill climb.”

L Mercer

“Hi Graham,
We ran our new LCR sidecar on the weekend that I fitted the Flatshifter Expert to. It`s terrific! Only a slight adjustment is needed & all is good. We dropped 1.3 seconds off our previous best time at the same track earlier this year. I’m very happy with the way it works. Thanks, Duncan Rogers Sidecar 55.
Am I happy? Yes ecstatic. Had a great deal of fun today with the Flatshifter Expert & Max combination and can’t wait to try it out on a track day. That said, this combo is equally happy on the road, fast or slow, and makes everyday driving so much easier in a BEC or Bike engined car.”

THE LATEST CUSTOMER FEEDBACK LETTER IS BELOW.

“We have very successfully run an early version of the quick-shifter/Flatshifter gear-change system for the last 10 years on an OMS Sprint car, and having studied all of the available makes and types of systems for a lightweight motorcycle engined single-seater for the new car we have constructed for this seasons racing, I decided to use the latest version the Flatshifter Expert This system is a very well engineered yet simple system, easy to install and set up, a real ” Plug and Play” in modern terminology. I became very aware of the over-complicated and programmer-reliant systems made by other manufacturers, and of course, the significant price differences between Flatshifter Expert, Max system & paddles seamless clutch shift system when these systems require replacement ECUs, and other major components.
Having installed the Flatshifter Expert to a Gen2 Hayabusa, with the Flatshifter electronic paddle shift, we have now run the car in two events, both without any faults in the system and winning FTD at Goodwood in only our second time out. I continue to be totally impressed by this system and fully recommend it to others. (FTD = (Fastest time of the day)”
