Pistonix Quarter
The ¼-mile ECU. No street compromise, total focus on the strip.
Quarter is the ECU for racers. It strips out everything that only matters on the street (eco modes, stock cluster integration, emissions compliance) and zeroes in on the strip: 4-stage launch control, anti-lag, adaptive two-step, slip-based traction control that understands motorcycle geometry, and 1kHz internal datalog on SD card.
Values may shift up or down before pre-order opens.
See pricing details →Roadmap after Phase 7, gated on Milwaukee Garage validation.

What is inside.
4-stage launch control
Dynamic RPM target by time, throttle position and oil temperature. Spool the turbo on the line.
Adaptive two-step
Holds RPM target at the holeshot even with ambient and battery voltage drift.
Anti-lag
Controlled misfire in the first seconds. Keeps the turbo charged through shifts.
1kHz SD datalog
32 channels at 1kHz recorded internally. Post-run analysis without a PC connected.
GPS launch trigger
Auto-detects line cross when fitted with the optional GPS module.
No-compromise mode
No traditional limp mode — sensor failure cuts the engine immediately. Race-only.
Who we built it for.
V-twin drag racers, big-turbo 2-step builds, dedicated track machines that never see public roads.
- Closed-course use only
- Mandatory off-road acceptance
- On-site tuning support at Milwaukee Garage Drag Racing
