High-Speed Quick Shifter Control for Supported aRacer ECU Systems.
The aRacer QSR V2 – Quick Shift Race V2 is a race-focused quick shifter expansion kit designed for supported aRacer RC Super X / Super XX and RC Mini X / Mini XX ECU systems.
Using a digital transmission design and MotoGP-grade piezoelectric sensor technology, the QSR V2 is built to deliver fast, accurate shift input detection for high-performance riding, racing, and development applications.
What It Is
A compact quick shifter expansion system for compatible aRacer ECU platforms. The QSR V2 collects shift sensor data up to 1,000 times per second, helping the ECU respond quickly and accurately during shift events.
What It Does
- Supports quick shifter functionality on compatible aRacer ECU systems
- Enables clutchless upshifts where properly configured and supported
- Supports downshift control on compatible electronic throttle / ride-by-wire applications where supported
- Uses high-speed digital signal processing for fast and accurate shift detection
- Collects sensor data up to 1,000 times per second
- Supports closed-loop shift control to help optimize shift timing and smoothness
- Uses MotoGP-grade piezoelectric sensor design
- Lightweight, compact design with self-diagnosis function
- Supports standard or reverse shift pattern setup where compatible
Performance Advantages
- Faster shift input detection compared with basic switch-style systems
- Closed-loop control helps reduce shift time and improve shift smoothness where supported
- Designed for sprint racing, track use, and high-performance riding
- ARRC top competition verified design
Compatibility
The QSR V2 must be used with a supported aRacer RC Super X / Super XX or RC Mini X / Mini XX ECU system. It is not a universal standalone quick shifter.
Compatibility depends on ECU model, vehicle application, throttle type, wiring configuration, shift sensor setup, and software calibration. Downshift functionality requires a compatible electronic throttle / ride-by-wire application and proper ECU support.
