Main harnessMini ECU Harness
Mini ECU main harness for connecting the corresponding controller to the engine management system. Termination type and supplied items are confirmed in the quote.
Controller
Compact standalone ECU with fully sequential four-cylinder control, built-in MAP and data logging.
Reference prices vary with exchange rates and the supplied package. Contact customer service to confirm the price, shipping and taxes.
01 / About Mini
MINI provides four sequential injector and ignition channels in a compact ECU. It includes MAP sensing, USB tuning and internal logging, making it suitable for projects with modest I/O requirements. Budget separately for an external wideband controller if lambda feedback is needed.
Up to four fully sequential cylinders with four high-impedance injector outputs.
Built-in 400 kPa absolute MAP sensor.
8 MB internal logging plus MTune USB setup.
Four high-impedance injector outputs; external wideband required.

Ask whether the price covers the controller alone or also wiring, connectors and a tuning cable.
04 / Fitment & installation: MaxxECU Mini ECU
Check the model, hardware revision and connector pins against the device’s wiring diagram.
Use the exact ECU wiring diagram; verify every circuit for continuity and shorts before connecting power.
Use the wiring drawing for the exact ECU revision. Calibrate sensors, synchronise base ignition timing and verify injector dead time before loaded tuning.
Use the MTune trigger scope and timing-lock function to verify synchronisation and measured ignition timing before load calibration.
05 / Questions about Mini
No. Use a compatible external controller and connect its calibrated analogue or supported CAN data. A bare oxygen sensor cannot connect directly to a 0–5 V input.
No. The model has no built-in throttle motor outputs. A throttle-position input is a measurement input and does not provide drive-by-wire motor control.
No. MINI can save data to its 8 MB internal memory, then connect to a computer to download it. Sampling rates and channel count affect recording duration.
MINI’s four injector outputs support high-impedance injectors, not SPORT / RACE low-impedance peak-and-hold drive.
MINI supports up to four cylinders fully sequential or eight with wasted spark. Injection and ignition strategies differ; match the engine’s trigger signals.
400 kPa is absolute pressure. Near sea level, subtracting about 1 bar of atmospheric pressure gives about 3 bar of gauge boost. Use the correct pressure units in the calibration.
No. Internal logging has 8 MB and rates up to 1000 Hz; USB PC logging is 20 Hz. Configure channels and rates in MTune; sensor update speed also limits usable data rate.
The software function needs a supported ethanol-content signal and an allocated input, plus suitable fuel, ignition and starting calibrations. The feature listing does not mean an ethanol sensor is built into the ECU or included in every package.
MTune provides an ignition timing lock for comparison with a timing light. Match the commanded angle to the measured crank angle and verify trigger configuration before load tuning. A displayed RPM value alone does not prove correct ignition phasing.
Allocate the output by its documented driver type and current limit. Many GPO channels are low-side control outputs, not a general high-current power supply. Use a suitable relay or power driver when the load exceeds the channel rating, and keep sensor grounds separate from load returns.
Protection depends on the measured signal and configured thresholds. For example, oil/fuel-pressure or exhaust-temperature strategies need valid matching inputs, and lean protection needs a valid lambda signal. Configure error handling as well as the limit values.
No. The ECU supports CAN communication, but the dashboard or module must use a compatible protocol, bit rate and channel configuration. Check the device’s documented MaxxECU profile or configure the supported CAN messages; connector shape alone does not establish compatibility.
MINI HOME cam synchronization uses one digital input, leaving one for speed or a switch. Digital inputs are Hall-only; raw VR signals need suitable conversion.
Its four ignition outputs are 5 V logic signals for a compatible ignition module, CDI or smart coil. A passive coil needs a suitable power stage; a logic-level output is not a high-current coil driver.
