MaxxECU SPORT Standard ECU Package with 3-Meter Flying-Lead Wiring Harness
Part Number: 1916
The MaxxECU SPORT Standard package is a universal standalone engine-management system for custom installations requiring up to six sequential fuel and ignition channels, electronic-throttle control, integrated wideband capability, flex-fuel support, variable-cam control, CAN communications, and sufficient supporting I/O for a well-equipped street or performance application.
SPORT occupies the practical middle of the MaxxECU range. It provides substantially more control capability than a basic cable-throttle 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, drive-by-wire throttle, variable valve timing, boost control, and CAN-controlled transmission hardware.
The Standard package includes the MaxxECU SPORT ECU, 3-meter flying-lead wiring harness, communication cable, MAP-sensor connection hardware, and installation documentation. Unlike the SPORT Premium package, it does not include a Bosch LSU wideband oxygen sensor or matching sensor connector.

Application Notes
• This is a universal flying-lead ECU package, not an application-specific terminated engine harness.
• The included SPORT harness uses approximately 3-meter conductors for custom routing and termination.
• This Standard package does not include a Bosch LSU wideband oxygen sensor or matching sensor connector.
• The SPORT ECU supports Bosch LSU 4.2 and LSU 4.9 sensors.
• The installed 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 MTune setup.
• Variable-cam control, transmission control, traction control, and other advanced functions depend on the available inputs, outputs, wiring, sensors, and configuration.
• Direct transmission control is available for selected GM 4L60E, 4L65E, 4L80E, 4L85E and Toyota A340E, A341E, and A650E applications.
• CAN-controlled transmission support includes selected BMW DCT, VAG DSG, and Gen 1 ZF 8HP applications.
• Gen 1 ZF 8HP control requires the appropriate MaxxECU transmission harness, compatible shifter hardware, transmission configuration, and CAN setup.
• MaxxECU SPORT does not include onboard knock-sensor inputs or direct Type-K EGT inputs.
