microRusEFI

microRusEFI is a small & cheap Engine Management System board designed for fully sequential 1, 2, 3 and 4 cylinder applications.
microRusEFI uses a waterproof connector and its aluminum enclosure could be sealed.
microRusEfi supports dual Hall shaft position sensor input or 1xHall + 1xVR shaft position sensor input (A few resistors must be replaced on the PCB to switch from one setup to another)
Open-source design available in this repository, or available as a kit or completely assembled.
This is an excellent option for racing series that allow modifications inside the stock ECU case.

Features

Primary VR or Hall input (configurable with few resistor changes)
Secondary Hall input
4 analog thermistor (temperature) inputs
10 analog voltage inputs (0-5v)
4 high-Z injector outputs
2 high-current low side outputs for IAC/VVT/other solenoids
Dedicated main relay control output
4 low-current low side outputs for relays or warning lights
4 5v logic-level ignition outputs
2 logic level outputs (5v/12v configurable, requires resistor changes)
Electronic throttle body (drive by wire)
CAN connectivity on the plug
USB connectivity on the plug
SPI and TTL available on PCB
