General description

Electronic full throttle upshifting, seamless acceleration - whether for racing motorcycles, streetmotorcycles, 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 additional accessories are 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 of different lengths are available, see accessories.
- Built on 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 ratios, acceleration, load, and engine speed are taken into account depending on the riding conditions. The interruption time is adjustable between 40-80 milliseconds.
- Simulates stable engine operation towards the ECU during the shifting process, thus allowing for a smooth and stable upshift. No error messages are generated, and it does not lead to unintended leaning out or enriching of the mixture formation.
- Integrated “Smooth Shift” to reduce load peaks on transmission and chain. Furthermore, during upshifting, the loss of traction, as with MotoGP shifters, is minimised. During the upshifting process, all cylinders are simultaneously shut off; traction is re-engaged by means of 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, and can therefore also be used for reverse shifting.
- All functions can be easily and problem-free programmed directly at the racetrack or on tour, without an additional device, using two buttons and the LED display.
- Supplied with ready-to-use connectors 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 taken from the ignition coil via the red cable, which leads directly to the CPU of the PQ8 shifter. Simple installation, as additional cable installation for 12V power supply is eliminated.
- 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 shifter at a specific and adjustable speed. The rider only has to keep the shift lever preloaded between shifts. Useful in “handicap” races where the rider must stay under the “break out” time. For this, the shift speed can be lowered to be deliberately 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 shifter. The majority of the power consumption from the PQ8 display is eliminated.
- Made in Sweden.
