ECUMASTER EMU Black vs EMU Classic: the differences

Both run up to six cylinders fully sequentially. The Black adds what modern engines and dashes need: drive-by-wire, CAN, the LSU 4.9 sensor, more inputs and two more injector outputs. If the engine has a cable throttle and no CAN devices, the Classic does the job.

From ECUMASTER’s own comparison and product pages; both have 2 knock inputs, 2 VVT controllers and one 500 mA +5 V supply.

Which one for your engine

Cable throttle, up to six cylinders, no CAN dash or keypad: the EMU Classic.
Electronic throttle: the EMU Black — the Classic needs an extra module for it.
CAN dash, PMU or keypad, or an LSU 4.9 sensor: the EMU Black.
Eight injectors or more inputs (flex fuel, switch inputs): the EMU Black.

Wiring differences

The grey 24-pin connector is laid out the same on both; only the black connector differs (24 pins on the Classic, 39 on the Black).
The Black needs a constant battery +12V on black pin 13 in addition to ignition +12V on grey pin 18; on the Classic grey pin 18 is the only supply.
The Black’s H-bridge pins are the Classic’s stepper pins — on the Black they are strong enough for a throttle motor.

Try both in WireForge

Place an ECU module and switch its preset between “ECUMASTER EMU Classic” and “ECUMASTER EMU Black” to see both connectors.
Wire your sensors and outputs to the named pins and check power, grounds and +5 V in the simulator.
Open the “ECU fuel injection” demo to see injectors and coils fire with the engine turning.

Questions

Do both run a six-cylinder engine sequentially?

Yes. ECUMASTER describes the Classic as full sequential six-cylinder without drive-by-wire, and the Black as the same with drive-by-wire.

Can the Classic run drive-by-wire?

Only with an external DBW module; the Black has the controller built in.

Can I move from Classic to Black later?

Yes: the grey connector carries over pin for pin, and the black one is repinned to the 39-pin plug.
