ECUType / MaxxECU

Maxx ECU


Compatibility


  • Maxx ECU V1
  • MINI
  • STREET
  • SPORT
  • RACE
  • PRO



Configuration

CAN data stream output must be activated in the ECU Mtune software:


Connections


  • MaxxECU has a built in termination resistor. External termination (120 ohm) is recomended for bus lengths over 1m.
  • Main connector: pin E1 = CAN H, pin E2 = CAN L
  • Wiring loom: Twisted pink/gray, pink = CAN L, gray = CAN H
  • Connect CAN high from the ECU to the ECU interface/DASH2pro/DL1club/DL1Pro/DL1WP CAN high
  • Connect CAN low from the ECU to the ECU interface/DASH2pro/DL1club/DL1Pro/DL1WP CAN low

Notes

  • Requires Maxx ECU Firmware version 1.67
  • Race Technology devices compatible with Maxx CAN protocol v1.2 & v1.3
