The CANBOXPRO is a universal CAN bus flex fuel and I/O controller designed for high performance applications requiring clean, OEM-level integration with the factory ECU.

Rather than intercepting or altering an existing factory signal, CANBOXPRO communicates directly over the vehicle CAN bus. Ethanol content and auxiliary sensor data are transmitted digitally to the calibration platform, eliminating analog signal manipulation and ensuring clean, accurate data delivery.

Beyond Flex Fuel: True I/O Expansion
While the CANBOXPRO is an industry-leading solution for Flex Fuel integration, it is also a fully reconfigurable I/O expansion hub. It features four dedicated channels that put total control back in the hands of the tuner.

Configurable I/O Breakdown:

2x 0-5v Analog Inputs: Monitor critical parameters that factory ECUs often ignore. Perfect for:

• Fuel Pressure
• Manifold/Boost Pressure
• Coolant Pressure
• Exhaust Backpressure
• Oil Pressure
• Crankcase Pressure

2x PWM Outputs: Take direct control of auxiliary systems:

• Boost Control Solenoids
• Secondary Fuel Pumps
• Methanol Injection
• Nitrous Systems
• Relay-Driven Accessories

Smarter Calibration Logic
Because all sensor data enters the ECU digitally via CAN bus, supported tuning platforms allow the calibrator to scale inputs directly within the calibration. This isn’t just data loggingthis is actionable intelligence. Tuners can tie these inputs directly into compensations, fail-safes, and protection strategies.

Trigger over-pressure, under-pressure, or system faults to initiate corrective action directly inside the ECU strategy.

Wireless Freedom
Integrated Bluetooth connectivity eliminates the need for clumsy laptop cables in the engine bay. Configure your device, run diagnostics, and perform firmware updates wirelessly using our dedicated iOS and Android applications. The CANBOXPRO is fully reconfigurable, making it the perfect foundation for staged builds that evolve over time.

ATTENTION ECUTEK TUNERS:
The CANBOXPRO is EcuTek CX29 certified and requires no custom CAN setup.
