Initial v1.0 support in v1.0.127, v1.1 support in v1.0.134


CANTCU-MaxxECU v1.0 (old)

MaxxECU WebHelp


  • Integrates as “CANTCU peripheral through CAN-bus (v1.1)
  • Integrates as an “External gearbox controller” through CAN-bus (v1.0)
  • Fully customizable control strategies for cuts/blips in MaxxECU
  • WheelSpeed input from CANTCU to MaxxECU (8HP transmissions)


CANTCU CAN3 is connected to the MaxxECU CAN-bus.

Torque Factor (CANTCU)

To achieve a somewhat realistic torque estimation, the VE (fuel) table needs to be tuned and MaxxECU correctly configured to show real-world VE values (Multiply Lambda). For this torque estimation we use a Torque Factor. The torque factor is generated from engine running values taken from a single point of running (usually maximum measured torque on a dyno run). The values needed for calculation are listed below.

  • Maximum Engine Torque (Nm)
  • Manifold Absolute Pressure, MAP (kPa)
  • Volumetric Efficiency, VE, Fuel Table (%)

Entering these values in the calculation window will generate a torque factor, which will be used as a baseline for torque calculations in the CANTCU.

Example of a calculated torque factor

WheelSpeed input to MaxxECU (8HP)

If using Simulated WheelSpeed in CANTCU, the WheelSpeed is broadcasted from CANTCU to MaxxECU. Be sure to select “CAN-bus” as Speed source under Speed/Gear in MTune.
