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.

• 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
