Universal 112

alt

This is our Wire-In open-source ECU base board compatible with Polygonus and Atlas ECU brain modules. It uses the Molex 112-pin connector. Inteded for custom wiring harnesses or OEM harnesses where you will cut and replace the original connector.

Features​

Data and Communication​

  • USB-B
  • Dual CAN bus

Inputs​

  • Dual wideband O2 sensor controllers using open source module (connected internally to CAN bus #2)
  • Dual VR crank/cam sensor inputs. VR input 2 uses adjustable threshold, suitable for low tooth count (single tooth cam, etc) applications (LS12 unavailable if used)
  • 11x Analog voltage Inputs (Weak pulldown to ground to avoid floating)
  • 4x Analog Temperature inputs (2.7k pullup resistor to 5v)
  • 6 digital inputs with integrated 2.7k pullup resistor to 5v. *Use for hall cam/crank sensors, switches, etc.)

Outputs​

  • 2x Electronic Throttle Body H-bridge drivers.
  • 20x Lowside outputs (LS1-16), 8 with freewheel diodes (LS9-12 and, optionally, IGN9-12)
  • 8 logic level ignition outputs (IGN1-8)
  • 8 ignition "dumb coil" IGBT drivers (IGN1-8, shared function with logic outputs, independent output pins)
  • Stepper motor driver for stepper idle (LS9/10 outputs unavailable if used)
