ECM-564x-112

The ECM-OH is a nice addition to the MotoHawk engine control line-up. It is a 24V engine controller for on-road applications.

The module is capable of full authority digital engine control (FADEC) consisting of fuel, spark, and air delivery to the engine. Additional inputs and outputs are available to control other system functions, as defined by software. This unit provides 112 connector pins with inputs, outputs, and communications interfaces that support a wide variety of applications.

The ECM-OH is part of the MotoTron Control Solutions ControlCore® family of embedded control systems. The ControlCore operating system, MotoHawk® code generation product, and MotoHawk’s suite of development tools enable rapid development of complex control systems.

Each controller is available in ‘F’ (Flash) or ‘C’ (Calibratible) versions. Flash modules are typically used for production purposes. Calibratible modules are typically for prototyping/development only; they can be calibrated in real time using MotoTune® or ToolKit.

Compiler Information

S12 micro (the saftey processor) requires Freescale Codewarrior 4.6.

The MPC5XXX micro uses either the GCC eabi SPE 4.6, or GHS 4.2.1 and 4.2.4.

Control Features

• 2 engine speed inputs: camshaft and crankshaft speed (software configurable for variable reluctance (VR) magnetic pickup sensor or Hall effect proximity sensor inputs)
• Up to 6 frequency inputs (some share analog resources)
• Up to 33 analog inputs
• 3 switch inputs
• 2 HEGO sensor inputs
• 2 LSU sensor inputs (also known as UEGO sensors)
• 2 knock sensor inputs
• 3 transducer power outputs providing +5V (350mA & 100mA) and +12V (100mA)
• 2 H-bridge driver outputs providing 10A and 5A drive capability and current sense feedback
• 6 Injector drivers providing software configurable peak and hold current levels (up to 7A/2A)
• 6 ignition coil drivers
• MPRD (Master Power Relay Driver) low side output
• TACH low side output
• 16 low side output drivers (1 with current sense feedback)
• 3 CAN (Controller Area Network) communications ports
• 4K-byte serial EEPROM for tunable parameter storage
• Auxiliary micro with 128k of flash, 8k of RAM, 4k of EEPROM

Watchdog Function

The ECM-OH will have an ETC monitoring microprocessor and the main power supply will have a HW watchdog that needs to be tickled by the main core processor.

Flexible Encoder

The ECM-OH will work with the flex encoder.

MotoHawk Compatibility

The ECM-OH is compatible with MotoHawk 2012b or later only. No older MotoHawk.

Datasheet Errata

The Datasheet says there are 8 injectors, 6 of which are peak-hold. This plan was the initial production intent, but it has changed. All production releases will only have 6 peak-hold injectors.

Availability

Calibratible versions are available now. Flash or production will be available in 2Q2013.
