Target engines of MaxxECU V1
  • All 1-12 cylinder engines (2/4-stroke)
  • Up to 8 cylinders fully sequentially
  • Up to 12 cylinders in wasted spark
MaxxECU V1 inputs
  • Intake air temperature sensor (IAT)
  • Coolant temperature sensor (CLT)
  • Throttle position sensor (TPS)
  • Lambda (WBO) sensor. Uses a sensor directly connected to the ECU without any additional electronics. Supports Bosch LSU 4.2 and 4.9
  • 2 trigger inputs. VR or digital. Automatic trigger level detection. The signals are processed by a completely separated processor for maximum performance and immunity against interference
  • 2 extra temperature sensors. Can be used as switches or to control additional functions
  • 2 extra 0-5V inputs. Can be used for additional sensors such as for measurement of fuel/oil pressure
  • 2 digital inputs used for example for speed sensors (VR / Hall) or switches
  • Built-in 400kPa MAP-sensor for up to 3bar/43PSI of boost
  • 8 inputs for EGT sensors. No extra electronics needed
MaxxECU V1 outputs
  • 8 peak/hold injector outputs. 1-2 high or low impedance injectors per output. 8A per output
  • 8 ignition outputs. 5V signal to drive ignition modules, CDI units or coils
  • 8 outputs for extra features. Can be used to control virtually anything. Fuel pumps, idle control, boost solenoids, nitrous, shift lights, fans, warning lights, etc. GPO 1-7 (2A) GPO 8 (5A)
