MAXXECU Expansion Module

MaxxECU Expansion Module Analog Inputs

• Accepts 0-5V analog or digital signals, max 24 V.
• Digital threshold: 3 V. Selectable 2.5 kΩ 5 V pull-up resistors.
• Analog update rate: Selectable up to 2 kHz. Input resistance: 200 kΩ.
• Switches/buttons and other slow signals in digital mode.
• Note: Ethanol sensors, etc. are not supported here - use PULSE inputs instead.

MaxxECU Expansion Module PULSE Inputs

• Accepts digital or VR signals, max 200 V, up to 30 kHz.
• Input resistance: 62 kΩ.
• Selectable digital, VR input or custom thresholds.
• 1kHz max update rate transmitted to the ECU.

MaxxECU Expansion Module 12V outputs

• 12 V sourcing output for general loads.
• Active = 12 V, off = floating.
• Max 5 A continuous. Protected against overload, short circuit. Flyback protection 30V.
• PWM up to 20kHz.
• Update speed 2ms (GEN1), 0.5ms (GEN2) (depening on CAN-bus load).

MaxxECU Expansion Module h-bridge outputs

• 12 V push-pull (half-bridge) output for motors or loads.
• Active = 12 V, off = ground.
• For bidirectional motors (e.g., throttles): connect the load between two H-bridge outputs.
• For general loads: connect the load between one H-bridge output and ground.
• Overload and short-circuit protected. PWM current-limiting.
• Max 7.5A–15 A (selectable), 10A continuous.
• PWM up to 20kHz.
• Update speed 2ms (GEN1), 0.5ms (GEN2) (depening on CAN-bus load).

MaxxECU Expansion Module technical

• Black powder-coated aluminium enclosure with IP68 environmental protection.
• Superseal 1.0 automotive connectors for reliable motorsport-grade wiring.
• Seamless CAN integration with MaxxECU and MTune, requiring no manual CAN message configuration.
• All inputs and outputs are protected against overvoltage, reverse polarity, overload, and short circuits.
• 12 analog inputs accepting 0–5 V analog signals or up to 24 V digital inputs with selectable pull-up resistors.
• PULSE inputs supporting digital or VR sensors up to 30 kHz with configurable input modes and thresholds.
• Selectable analog input sampling rates of up to 2 kHz, with pulse data transmitted to the ECU at up to 1 kHz.
