General Description

Electronic full-throttle upshifts, seamless acceleration - whether for racing motorcycles, streetn motorcycles, 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 has been developed with the latest technology and is continuously optimised through its use in racing series worldwide.

Features:
- Stand-alone system: no further accessories are required.
- Easy to reverse.
- 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. Further shift rods of different lengths are available, see accessories.
- Built on the most advanced GP technology and completely computer-controlled via a 20 MHz CPU. Programming via a 2 tip switch system.
- Compu Shift calculates the perfect interruption time for each individual upshift. From a selection of 500 interruption times, various engine conditions, acceleration, load, and engine speed are taken into account depending on the riding situation. The interruption time is adjustable between 40-80 milliseconds.
- Simulates stable engine operation towards the ECU during the shift process, allowing for smooth and stable upshifts. This does not generate any error messages and does not lead to unwanted leaning or enriching of the mixture.
- Integrated “Smooth Shift” to reduce load peaks on the transmission and chain. Furthermore, the loss of traction during upshifts is minimised, similar to MotoGP quickshifters. During the upshift, all cylinders are simultaneously shut down, and traction is re-engaged through a computer-controlled 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 push and pull, therefore can also be used for reverse shifting.
- All functions can be easily and seamlessly programmed directly at the racetrack or on tour, without an additional device, 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, correspondinge wiring harnesses are available through the Cordona distribution network. For other ignition coil systems, installation is not “plug and play” but remains uncomplicated.
- 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. Easy installation, as additional cable installation for 12V power supply is eliminated.
- Automatic on/off switching controlled via speed. Fully adjustable to prevent unwanted engine shutdown by shifting into neutral during idle speed.
- Audible signal generator for acoustic feedback during functional testing 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 merely 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 now indicates that the system is ready. Very useful if a battery pack is used to power the quickshifter. The majority of power consumption is eliminated from the PQ8 display.
- Made in Sweden.
