The Paddle Shift Auxiliary Kit is designed as a hardware solution for integrating paddle shift with a sequential racing gearbox.

It is intended for use with a MoTeC GPRP-M1 engine management system, which comprises an M1 ECU and the GPRP firmware Package featuring paddle shift control.

• Includes two carbon fibre steering wheel mounted paddles (momentary switches) for up/down shifts to the ECU.
• Includes carbon fibre steering wheel mounting plate for paddles and buttons.
• The push/pull pneumatic actuator will allow both up and down shifts through two in-built solenoid valves. Valve timing is controlled through the ECU paddle shift function.
• The pneumatic pump supplies air pressure to the tank and is activated by the ECU with specific control of pressure including a pressure sensor fault fall back strategy.
  • If the sensor fails or is not present, the ECU can automatically cycle the pump to maintain a pressure supply. Excess air pressure is relieved through the pressure relief valve supplied in the kit.
• The air tank and manifold supply a strong reserve of pressurised air for shifts. The manifold includes ports for all necessary fittings and a pressure sensor for the pump control.
• The tank to pump pressure line comes as a standard 1.5m length but can be shortened using simple tools. It is included with the air tank manifold kit but is also available as a spare part.

• Paddles can be wired to any digital, universal digital or analogue voltage input pin.
  • Option for single input wiring see: Paddle wiring
• The pneumatic actuator can be wired directly to the ECU without the need for an external amplifier or relay. Two half-bridge, peak hold injector outputs or low side outputs can be used; one output for up shifts and one output for down shifts.
• The pneumatic pump is controlled by the M1. It can be powered either from a MoTeC PDM using CAN or a directly wired high current relay using a Half Bridge, Peak Hold Injector or Low Side output.
• The tank pressure sensor can be wired to any analogue voltage input.

Paddle Shift Sequence:

1. The request to begin a shift comes from the driver paddle.
2. The system cuts or blips the engine via the injectors, coils or Drive by Wire.
3. The Shift Actuator moves the gearbox between the gears.
4. When the next gear is reached, power is reintroduced.
