ECUMaster EMU Black


  • Integrates as an “ECM Switch board”
  • Uses values from “EMU stream” and a single custom Tx CAN frame
  • Cut/retard based on CAN request
  • Two different blip strategies (CANTCU/ECU controlled)


CANTCU CAN3 is connected to ECUMaster CAN-bus.

Software Configuration

  • In ECUMaster, ECM Switch board of type CSB V3 0x640 needs to be enabled. CAN-bus speed/bit rate can be adjusted to suit project-specific requirements, default speed is 500kb/s.
  • ECUMaster EMU Stream (CAN) needs to be enabled on the used CAN-bus. Base ID can be freely configured.
  • Inputs for cut/blip are sent from CANTCU as digital/analog channels

ECUMaster Tuning

Torque Factor (CANTCU)

To achieve a somewhat realistic torque estimation, the ECU VE (fuel) table needs to be tuned and show real-world VE-values. 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

Blip Control (CANTCU)

If CANTCU Blip Control strategy is used to control blips, the RT-value Throttle Blip is used as initial setpoint. Some extra adjustable parameters are available for fine tuning.

  • Max Blip Throttle - Maximum DBW Throttle opening %
  • Decel Blip - Sensitivity/Gain on deceleration/overrun
  • Driving Blip - Sensitivity/Gain while TPS (Pedal) > 0 %
