Turbosmart BlackBox Electronic Wastegate Controller

This electronic wastegate controller is a dedicated control unit built for use alongside a range of factory, aftermarket and motorsport ECUs, managing boost pressure by translating both basic and advanced boost control strategies into precise gate position commands. It's designed for use on single or twin electronic wastegate setups, giving serious tuners fine-grained control over boost delivery.

Built as a dual-channel, high-current-capable H-Bridge driver, this controller is designed to work with a range of electronic external wastegates, including straight-flow and poppet-style gate designs. It accepts multiple input strategies, including PWM signals as used with traditional boost control solenoids, 0–5V position targets, and CAN bus position targets, along with CAN bus override capability for advanced ECUs where a fully custom control strategy is needed.

Auto-calibration is built in, using a full actuator sweep to set up electronic external wastegates accurately without manual tuning, while integrated over-temperature safety features use onboard temperature sensor inputs to protect the actuator from heat-related damage. The unit ships pre-configured with flow-versus-lift calibration data for a range of electronically actuated wastegates, simplifying initial setup considerably.

Settings can be adjusted through a straightforward USB connection and PC-based software application, with unlimited control strategies achievable through the CAN-based override system — the only real limit being your ECU's own capability to develop and send a custom strategy.

For serious turbocharged builds running electronic wastegates, this controller offers precise, configurable boost management with genuine motorsport-grade calibration and safety features, whether you're running a single gate setup or a more complex twin-gate configuration.

Installation and setup typically require some familiarity with tuning software and ECU integration, so this controller is best suited to experienced tuners or professional workshops rather than a first-time DIY boost control upgrade. Taking time to properly complete the auto-calibration sweep before fine-tuning control strategies helps ensure the most accurate baseline for further adjustment.
