Engine control units

ECUMASTER built the module specifically for demanding common-rail diesel injection, an area few stand-alone engine controllers cover well; it works alongside EMU PRO rather than as its own controller.

ECUMASTER states the pairing keeps fuel pressure stable under high loads, supports oversized injectors and gives a smoother launch with less smoke, covering engines up to eight cylinders.

Two versions are offered: EMU PRO-16 for builds needing a high input/output count, and EMU PRO-8 for smaller engines of up to eight cylinders. Fitting a GDI Driver lets either version run direct-injection engines.

Versions

• EMU PRO-8 (up to 8 cylinders)
• EMU PRO-16 (higher I/O count)
• Accessory: preterminated labeled wiring harness for EMU PRO

Enclosure

EMU PRO strategy

Control of pressure for up to 2 high pressure fuel lines; adjustable injection timing; control of up to 16 injectors (8 direct via GDI Driver + 8 port injectors direct on EMU PRO); configurable fuel injection split between port and direct rails; support for multiple fuel pump cam types; support for multiple high pressure pumps; variable rail pressure target

It steps injector voltage up for fast, precise response and can run two high-pressure pump valves, with CAN bus diagnostics for live monitoring and logging.

ECUMASTER supplies ready base maps for common applications, including the VAG EA888 Gen 3, and states more will be added.

Changes from the original EMU include upgraded ignition outputs able to drive more than one active coil per channel, a separate 5V regulator for sensors, better-protected stepper outputs, a galvanically isolated USB port and a smaller CNC-machined enclosure.

EMU and EMU CLASSIC share the same firmware and client software. It manages fuelling, ignition and auxiliary systems on one to twelve-cylinder engines, including drive-by-wire with an external module and variable valve timing, and ECUMASTER says its adaptable trigger decoding can support crank patterns not yet released.

Built-in features include a wideband lambda input wired directly to a Bosch LSU 4.2 sensor, an onboard MAP sensor, two EGT probe inputs and an ethanol-sensing port for Flex Fuel, alongside software such as switchable maps, launch control, adaptive lambda tuning and wheel-slip management.

For most applications it allows the factory airflow meter to be removed, drives up to four injectors in batch-fire mode and adjusts ignition timing through 16x16 tables, with parametric outputs configurable for boost control, nitrous activation or water/methanol injection.

In its "Fuel Implant" mode the DET3 behaves more like a stand-alone ECU, working out fuelling from RPM, intake air and coolant temperature and throttle position, plus oxygen-sensor feedback where fitted.

Versions

• DET3 (standard piggyback mode)
• DET3 FI (Fuel Implant standalone fueling mode)
