MaxxECU SPORT Standalone ECU — ECU Only

MaxxECU SPORT Standalone ECU — ECU Unit Only

Part Number: 1914

The MaxxECU SPORT is a universal standalone engine-management system for custom applications requiring up to six sequential fuel and ignition channels, electronic-throttle control, integrated wideband lambda, flex-fuel capability, variable-cam control, CAN communications, and supporting I/O for a well-equipped street or performance vehicle.

SPORT occupies the practical middle of the MaxxECU range. It provides drive-by-wire control, Bluetooth communication, peak-and-hold injector drivers, and more flexible I/O than the STREET ECU without requiring the additional channels and specialized inputs of the larger RACE and PRO systems. It is particularly well suited to four-, five-, and six-cylinder engines using sequential injection, individual ignition coils, electronic throttle, variable valve timing, boost control, and CAN-controlled transmission hardware.

This listing is for the MaxxECU SPORT control unit without the installation harness, wideband sensor, or package accessories. It is best suited to replacement installations, custom harness builders, or applications where the required MaxxECU wiring and accessories are already available.

Key Features

• Controls engines with up to six cylinders using fully sequential fuel injection and ignition
• Supports engines with up to 12 cylinders using non-sequential fuel and wasted-spark ignition strategies

• Built-in wideband lambda controller supporting Bosch LSU 4.2 and LSU 4.9 sensors
• Built-in 400 kPa absolute MAP sensor, suitable for approximately 3 bar or 43.5 psi of boost
• Dedicated TPS, coolant-temperature, and intake-air-temperature inputs
• Six additional 0–5 V analog inputs for pressure sensors and other analog devices
• Two additional temperature inputs and two digital inputs

• Internal data logging at up to 1,000 Hz
• Flex-fuel, variable-cam, boost-control, traction-control, launch-control, anti-lag, and engine-protection strategies
• MTune PC software for setup, tuning, diagnostics, and data analysis

Application Notes

• This listing is for the MaxxECU SPORT control unit without the SPORT flying-lead wiring harness or a Bosch LSU wideband oxygen sensor.
• Installation hardware and accessories supplied with the SPORT Standard and Premium packages are not included with this unit-only SKU.
• A compatible MaxxECU SPORT harness or connector and terminal set is required to install the ECU.
• The SPORT ECU connector is not interchangeable with connectors used by other MaxxECU models.
• A compatible USB communication cable is required for direct connection to a Windows PC running MTune.
• Bluetooth operation requires the appropriate MaxxECU mobile antenna if one is not already available.
• The ECU supports Bosch LSU 4.2 and LSU 4.9 wideband sensors. The sensor, connector, wiring, and MTune configuration must match.
• Full sequential operation is limited to engines with six cylinders or fewer. Engines with more than six cylinders require a different fuel and ignition strategy or a higher-channel MaxxECU model.
• The ignition outputs do not directly drive conventional high-current ignition coils. Use coils with built-in igniters, a compatible external ignition module, or a CDI system.
• Electronic-throttle operation requires a compatible throttle body, accelerator-pedal assembly, correct wiring, proper channel allocation, and application-specific setup in MTune.
• Supported direct-control automatic transmissions include selected GM 4L60E/4L65E, GM 4L80E/4L85E, and Toyota A340E/A341E/A650E applications.
• Supported CAN-controlled transmission applications include selected BMW DCT, VAG DSG, and Gen 1 ZF 8HP systems.
• Gen 1 ZF 8HP control requires the appropriate MaxxECU transmission harness, compatible shifter hardware, transmission configuration, and CAN setup. These components are sold separately.
• MaxxECU SPORT does not include onboard knock-sensor inputs or direct Type-K EGT inputs. External modules or signal conditioners are required where those inputs are needed.
