This Plug-In Kit is designed as a complete replacement for the factory OE (original equipment) ECU, using existing wiring, sensors and mounting hardware to deliver plug-in convenience with fully programmable control. The ruggedised M150 ECU is supplied with the Package preloaded, providing complete functionality for the Mercury Racing QC4V engine. The Package is based on MoTeC's GPR Package with additional features unique to this engine.

Along with dual drive-by-wire, fuel, ignition and dual turbocharger control, this Package adds knock control to the QC4V and also supports OE ECU features, including:

• Key start
• OE dash or MoTeC dash operation via OE CAN busses
• Trim up and trim down control
• Gear forward and reverse operation
• Trim tab position port and trim tab position starboard monitoring
• Stern leg position monitoring

The start file supplied in the Package contains all the calibrations and settings for the sensors, fuel injectors, ignition coils, knock control, throttle servo and turbocharger wastegates. Users can begin tuning to their desired power level right away with the assurance of a safe base tune that is equivalent to the original ECU.

In addition, as the OE CAN bus systems operate at 250 kbit/second, a restricted version of MoTeC's pre-defined CAN messaging is used to allow the addition of E888, LTC, and Display Loggers without overloading CAN communications.

In particular, an E888 I/O Expander with 250 kbit/second CAN messaging is available for use with this Plug-In Kit.

• Fully integrates with these OE systems: key start, trim up/down, gear forward/reverse, servo wastegates, dash.
• Lambda control is supported with included LTCD NTK and NTK sensors, requiring additional installation.
• Pre-configured sensor calibrations for OE sensors and engine triggers including:
  • Exhaust EGT port and starboard
  • Fuel tank level
  • Trim tab position port and starboard
  • Stern leg position
  • Shift pressure B
  • Steering angle
  • Steering pressure
  • Engine oil temperature
  • Engine oil pressure
  • Fuel pressure
  • Coolant pressure

• Pre-configured control of primary fuel system.
• Pre-configured reference mode for engine synchronisation.
• Pre-configured physical settings for engine displacement, fuel density, stoichiometric ratio, fuel pressure, and primary injector linearisation, which allow for simplified engine start-up prior to tuning.
• Pre-configured CAN messaging for OE systems including key start, throttle pedal and dashboard.
• Pre-configured transient fuelling compensation using physical modelling of fuel film.
• Pre-configured on-board knock control for each cylinder using two included knock sensors (optionally can be configured to use up to 4 sensors) and selectable centre frequency.
• Configurable boost control with dual OE wastegate actuators.
• Configurable anti-lag with ignition timing limit, fuel volume trim, ignition cut, fuel cut, engine speed limit, boost aim and throttle aim tables.
• GPS acquisition and logging via CAN or RS232.
• Intercooler temperature and spray control.
• Lap distance, time and number with split and sector options via MoTeC's BR2 (Beacon Receiver) or switched input.
• Configurable launch control with tables.
• Race time system with tables for ignition timing trim, fuel mixture aim, boost limit, and throttle limit.
• Engine load average channel with tables for engine speed limit, ignition timing trim, fuel mixture aim, boost limit, and throttle limit.
• Engine run time total for engine hour logging.
• Configurable security for multiple users with differing access options.
• ECU CAN receive from a defined ID base address for data reception from MoTeC devices.
• 6 configurable driver switches, 4 rotary switches and 6 CAN switches each with 9 positions that can be simultaneously mapped to launch control, pit switch, anti-lag, traction, race time reset, engine speed limit maximum, throttle pedal translation, fuel volume trim, ignition timing, fuel mixture aim, boost limit, traction aim, and traction control range.
• Pulsed tachometer output with configurable output pin and scaling.
• Optional channels for additional sensors via input pin and/or CAN message, including:
  • Airbox Mass Flow, Temperature and Pressure
  • Ambient Pressure and Temperature
  • Engine Crankcase Pressure
  • Exhaust Pressure Bank 1 and Bank 2
  • Exhaust Temperature (EGT) via TCA Thermocouple Amplifier, Generic CAN or E888 for Collector, Bank 1 and 2 Collector, and Cylinders 1 to 8
  • Exhaust Lambda via LTC, LTCN or PLM for Collector, Bank 1 and 2 Collector, and Cylinders 1 to 8
  • Fuel Temperature
  • Intercooler Temperature
  • Transmission Temperature
  • Turbocharger Speed
  • G-Force (acceleration) - Longitudinal, Lateral, Vertical.
