OVERVIEW

Introducing M670

The M670 is a 154-pin high-feature Engine Control Module (ECM) designed to support Model Based Controls development for Gasoline PFI, Diesel Solenoid and alternative fuel applications up to 8 cylinders.  The configurable M670 is perfectly suited for replacing an OEM ECM for engine development programs.

The Electronic Control Unit (ECU) integrates a broad range of Engine Control features such as dual ETC, quad V.V.T, VGT, dual Knock, UEGO, HEGO and more.

The M670 ECU can read a pulse-width based directional hall-effect crank sensor and providing a measurement of the current crank position even if the crank has stopped or moved backwards. This feature is useful for start-stop feature. With constant current drive feature the M670 can be used for Transmission Control Unit (TCU).

Dana’s systems, controls and software engineers are available to support application implementations from prototype to production.

APPLICATIONS

M670 Applications Include:

Application Description
Engine Control Module (ECM) The M670 is suited for engine development, prototyping and production applications. Internal Combustion applications include:

  • Common Rail Diesel ECM
  • Gasoline Direct Injection (GDI) ECM
  • Gasoline Port Fuel Injection (PFI) ECM
Replace OEM ECM Engine development programs in certain scenarios require access to the ECM. The M670 is suited to replace OEM ECU providing complete development access to engine control design and development.
Transmission Control Unit M670 is suited for transmission control of Dual-Clutch Manual (DCT), Auto Shifting Manual (ASM) and traditional automatic transmissions with two high current H-bridge drivers and up to 8 current controlled solenoid drivers.
