UAEFI

|UAEFI



uaEFI is a small & cheap Engine Management System board designed for fully sequential Fuel/Igniton on six cylinder applications.
uaEFI utilizes a compact form factor allowing it to fit in oem enclosure adapters or a 3D printed case with molex Connectors for wire-IN solutions.
uaefi supports dual Hall shaft position sensor input or 2xHall + 2xVR position sensors input (may require jumper adjustments.)
Open-source design available in this repository, or available as a completely assembled ECU.
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)
  • Third Hall (VSS) input
  • 2 analog thermistor (temperature) inputs
  • 3 analog (AUX) inputs
  • 2 TPS inputs
  • 6 high-Z injector outputs
  • 2 high-current low side outputs for IAC/VVT/other solenoids (DC1,DC2)
  • Dedicated main relay control output
  • 4 low-current low side outputs for relays or warning lights
  • 6 logical-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

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 completely assembled ECU.
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
