canDO Valve Controller — clean, OEM‑style control for your exhaust valves.
The canDO Valve Controller provides clean, OEM-style control of your car's exhaust valves—whether one or several—through a dedicated mobile app, without relying on extra remotes. Set the valve states you want, and they behave the way you configure them every drive.
- Mobile app control (no extra remotes)
- Configurable valve positions from 0% to 100% open, or OEM control
- Quiet Start mode for reduced noise at startup
- Over-the-air (OTA) firmware updates
- Automatically adjust valves based on GPS coordinates with user-defined Zones
- Clean integration — and best results when bundled with canDO+
Designed to fit. Simple, configurable control of your exhaust valves that integrates cleanly into daily driving.
What it does
The Valve Controller is a dedicated exhaust valve solution focused on predictable behavior and a clean user experience. The canDO Valve Controller replaces add-on transmitters and garage remotes with control from a mobile app.
Consistent behavior
Set the valve states you want and get the same result every time the car starts.
No remotes
Use the mobile app instead of carry-around transmitters, garage door remotes, or extra switches.
OEM-minded integration
Designed to feel like a factory feature, not an aftermarket add-on with compromises.
Only on canDO
No other exhaust valve controller on the market offers these capabilities.
App-controlled valve positions
Control your exhaust valves from the canDO mobile app — no remotes, no aftermarket switches. Set OEM mode to mirror factory behavior, or pick a fixed open percentage from your phone (25%, 50%, 75%, 100%).
1% precision positioning
Set valves to any position from 0% to 100% in 1% steps. No other controller on the market offers this level of precision.
ECU + offset mode
Keep what the ECU is asking for — quiet at idle, open under throttle — and add a constant 25%, 50%, or 75% on top. Valves still respond to your driving, just more open across the board. Only canDO has this mode.
ECU × multiplier mode
Scale whatever the ECU is requesting by 1.25×, 1.5×, 1.75× or 2×. Closed when the factory map says closed, progressively more open everywhere else — same OEM shape, dialed up. Found only on canDO.
Zones
Define zones — your neighborhood, work, the track — and valve positions follow automatically as you cross boundaries. Quiet Start layers on for ignition: override your normal defaults on startup for quieter first moments, add time-of-day windows, and tie it to zones so it only runs where and when you choose. The only valve controller on the market with automation this flexible.
Live telemetry
See live valve position data, along with speed and acceleration — right in the app. The only valve controller with telemetry feedback.
