ECUMaster EMU Pro 16 is a 120-pin wire-in ECUMaster ECU on 4 connectors: A (34 pins), B (26 pins), C (34 pins) and D (26 pins).
It has 16 injector outputs and 12 ignition outputs. The injector drivers are peak-and-hold, so low-impedance injectors run without a resistor pack. Most ignition outputs fire dumb coils directly; the rest are smart-coil only.
There is one dedicated trigger input, each happy with a VR or a Hall sensor. Two knock inputs cover both banks of a V engine. It has 2 onboard wideband controllers, so a sensor wires straight in. MAP is an external sensor on an analog input.
Drive-by-wire is native: 2 throttles from its own H-bridge outputs. Two CAN buses handle dashes, PDMs and expansion. The maker rates the 5V sensor supply at 4000 mA in total.

Which builds it suits
Of the 58 swap presets in the planner, 53 fit as they are and 4 fit with add-ons; 1 does not fit at all. The add-on it asks for most often is a direct-injection driver module. Where it falls short, it is usually not enough knock inputs. The planner fills anything a preset leaves open with its ordinary defaults, so your own build may land differently.
It runs the Toyota 2JZ-GTE non-VVTi, Ford Modular 4.6 2V (SOHC), Nissan RB26DETT (R34, smart coils) and Subaru EJ/FA FA20D (BRZ/86 NA) presets with nothing added. The GM LT1 (Gen5 6.2 alum) needs a direct-injection driver module. The Subaru EJ/FA FA20DIT (WRX turbo 2015+) needs a direct-injection driver module. It can't run the BMW S54 (3.2 NA I6, E46 M3): not enough knock inputs.
