General Description

Electronic full-throttle upshifts, seamless acceleration – whether for racing motorcycles, streetnmotorräder, drag bikes, go-karts, cross-karts – basically anything with a sequential transmission. The PQ8 does not trigger an error message in engines with fuel injection. The PQ8 was developed with the latest technology and is continuously optimised through its use in worldwide racing series.

Features:
- Stand-Alone system: no additional accessories required.
- Easy reversal possible.
- Supplied with a universal shift rod (6 mm internal thread). This may need to be shortened to the correct length depending on the footrest system used. Other shift rods in different lengths are available; see accessories.
- Built on advanced GP technology and fully computer-aided with a 20 MHz CPU. Programming via 2 tip switch system.
- Compu Shift calculates the perfect interruption time for each individual upshift. With a choice of 500 interruption times, various engine ratios, acceleration, load, and engine speed are taken into account depending on the riding conditions. The interruption time is adjustable between 40-80 milliseconds.
- During the shifting process, it simulates stable engine operation to the ECU, thus allowing for a smooth and stable upshift. This generates no error messages and does not lead to unintended leaning or enriching of the mixture.
- Integrated “Smooth Shift” to reduce peak loads on transmission and chain. Furthermore, when upshifting, the loss of traction, as with MotoGP quickshifters, is minimised. During the shifting process, all cylinders are switched off simultaneously; traction is reapplied via a computer-aided sequence, in conjunction with Compu Shift.
- Solid, waterproof housing and high-quality wiring harness. The circuit board is fully potted and equipped with a 26-pin aviation standard connector.
- Very high-quality sensor based on strain gauge technology.
- Sensor works on pressure and pull, therefore can also be used for reverse shifting.
- All functions can be easily and effortlessly programmed directly at the racetrack or on tour, without additional equipment, using two buttons and the LED display.
- Supplied with ready-to-use plugs for Denso and Mitsubishi ignition coils, which are used in most Japanese sport motorcycles, as well as Triumph and KTM vehicles [For KTM Superduke R 2008, Beru ignition coils are installed; please use the wiring harness for Ducati 749 here]. For Ducati 748-998, 749-1198, Aprilia RSV 4, MV Agusta 2 and 4 ignition coils, corresponding wiring harnesses are available through the Cordona distribution network. For other ignition coil systems, installation is not “plug and play” but remains straightforward.
- For vehicles with coil-on-plug ignition coils, the +12V power supply is provided by the ignition coil via the red cable, which leads directly to the CPU of the PQ8 quickshifter. Simple installation, as additional cable installation for 12V power supply is not required.
- Automatic on/off switching controlled via speed. Fully adjustable to prevent unintended engine shutdown by shifting into neutral during idle speed.
- Audible signal generator for acoustic feedback during functional tests and commissioning. Very useful when installed behind fairings.
- Auto Shift, for “drag racing” only, can be selected to automatically activate the quickshifter at a specific and adjustable speed. The rider only needs to keep the shift lever preloaded between shifts. Useful in “handicap” races where the rider must stay below the “break out” time. The shift rpm can also be lowered to intentionally be slower in subsequent races.
- Power saving: if no input is made via the PQ8 display for 60 seconds, the electronics enter power-saving mode. A blinking dot then indicates that the system is ready. Very useful if a battery pack is used to power the quickshifter. The majority of power consumption for the PQ8 display is eliminated.
- Made in Sweden.
