Introduction

A modular controller brings smooth, smart, and customizable exhaust-valve control to performance vehicles.

Active Exhaust Valve Control

Precision Control for Tuned Exhausts

Active exhaust systems have become a favorite upgrade in the tuning world. They let drivers switch between quiet cruising and full-throttle sound with ease. The GOcontroll Moduline Mini I offers a compact and rugged way to automate these valves based on RPM, throttle position, or custom schedules. Because the controller is modular and easy to program, it gives builders and tuners a flexible platform that fits many vehicle setups.

A Compact Controller for Performance Builds

The Moduline Mini I includes an i.MX 8M Mini processor, two CAN 2.0B interfaces, Ethernet, USB, and four module slots. Its CNC-milled aluminium housing adds durability for under-hood or trunk-mounted installations.
Tuners can choose input modules to read RPM, throttle signals, or driver-selected modes. Output modules then control the electric exhaust valves directly. Because the system is modular, it adapts to almost any exhaust-valve hardware without redesigning the installation.

Smooth Valve Control Based on Engine Signals

Active exhaust valves change the character of the car instantly. The Moduline Mini I reads RPM and throttle data in real time through CAN or analog inputs.
Furthermore, the controller reacts quickly to changing conditions. When RPM rises, it can open the valve for more sound. When the driver lifts off, it can close the system to keep the cabin quiet. As a result, the exhaust system feels smooth, predictable, and far more refined compared to manual switches.

Quiet Mode, Sport Mode, and Custom Logic

Many drivers want silent starts early in the morning. Others want a louder profile at highway speeds. With the Moduline Mini I, tuners can program:

  • Quiet-mode schedules

  • RPM-based transitions

  • Throttle-percentage thresholds

  • Driver-selected modes

  • Time-based or temperature-based behavior

Because the controller runs Linux and supports flexible logic, builders can create profiles that match the exact sound and comfort level the customer wants.

Visual Dashboards Through Node-RED

Node-RED comes preinstalled on the controller. It gives tuners a simple way to build dashboards for valve state, RPM, throttle input, and mode selection.
Additionally, builders can offer customers a browser-based interface to switch modes from their phone or laptop. Since Node-RED supports MQTT, HTTP, and more, it also enables remote logging or performance analysis for shops that want deeper insights.

Easy Integration With Modern Vehicle Systems

Many modern cars share engine data over CAN. The Moduline Mini I reads this data smoothly, which simplifies installation and reduces wiring. Tuners can tap into RPM, throttle, and other values without adding extra sensors.
Because the platform accepts multiple module types, it can also interface with older vehicles that need analog or 4–20 mA sensor inputs. This makes it a strong fit for both classic builds and modern performance cars.

Built for Tuning Shops and Custom Builders

Exhaust-valve control often evolves with the rest of the build. Fortunately, the Moduline Mini I grows with it. Tuners can add new modules, switch control logic, or update modes as the car changes. Its rugged design and compact size make it reliable for long-term automotive use.
Therefore, tuning shops, custom builders, and performance enthusiasts gain a stable and flexible controller that delivers precise sound control and a more exciting driving experience.
