Description
The canDO Valve Controller delivers clean, OEM-style exhaust valve control for BMW performance vehicles. Designed for seamless integration and predictable operation, this advanced valve controller allows full control of one or multiple exhaust valves directly from the canDO mobile app — eliminating the need for aftermarket remotes, transmitters, or extra switches.
With configurable valve behavior, GPS-based automation, Quiet Start functionality, live telemetry, and advanced ECU integration modes, the canDO Valve Controller provides one of the most sophisticated exhaust valve management systems available.

What the canDO Valve Controller Does
The canDO Valve Controller replaces traditional aftermarket valve remotes with a modern app-based control system that feels factory integrated.
Drivers can:
- Set fixed valve positions
- Use OEM valve behavior
- Create automated valve rules
- Configure startup preferences
- Monitor valve activity in real time
The result is consistent exhaust valve operation every time the vehicle starts and throughout daily driving.
App-Controlled Valve Positions
Control exhaust valves directly from the canDO mobile app without aftermarket switches or remote transmitters.
Available control modes include:
- OEM factory behavior
- Fixed valve opening percentages
- 25% open
- 50% open
- 75% open
- 100% open
The app provides simple and repeatable control directly from your phone.
1% Precision Valve Adjustment
The canDO Valve Controller supports valve positioning in precise 1% increments from fully closed to fully open.
This allows highly customizable exhaust sound and airflow tuning that exceeds the capabilities of traditional valve controllers.
ECU + Offset Mode
Maintain factory ECU-controlled valve behavior while increasing valve opening by a fixed percentage.
Examples:
- Add 25% additional valve opening
- Add 50% additional valve opening
- Add 75% additional valve opening
The valves still react naturally to throttle and driving conditions while remaining consistently more open.
ECU × Multiplier Mode
Scale the ECU’s valve requests dynamically while preserving factory valve logic.
Multiplier settings include:
- 1.25×
- 1.5×
- 1.75×
This keeps OEM-style progression while increasing overall exhaust valve response across the operating range.
Zones & GPS-Based Automation
The canDO Valve Controller supports advanced geo-based automation using customizable GPS Zones.
Create automated behaviors for locations such as:
- Home
- Neighborhoods
- Work
- Race tracks
- Specific driving areas
Valve behavior automatically changes as the vehicle enters or exits selected areas.
Quiet Start Functionality
Quiet Start mode reduces exhaust noise during vehicle startup.
Features include:
- Startup-specific valve overrides
- Time-of-day scheduling
- GPS Zone integration
- Quiet operation in selected locations and times
This creates a quieter startup experience without sacrificing full performance control during driving.
Live Telemetry Monitoring
View real-time data directly inside the canDO app.
Telemetry includes:
- Live valve position
- Vehicle speed
- Acceleration data
This provides instant feedback and monitoring while driving.
