RaceROM Custom Features for the ECM and TCM

RaceROM Custom features are written into our tuning software to give you unique features that don’t come as standard. They need to be set up by an EcuTek tuner, and you may be charged extra as they take time to configure.

  • Four-way Map Switching
    • Swap between four different maps using either the cruise control buttons or ECU Connect on your mobile device. Have your tuner set up a track map, a street map, an economy map and a self adjusting Flex map for example and switch between them on the fly. Which map you are in will be indicated on the rev counter.
  • Self Adjusting FlexFuel
    • No more worries about calculating the ethanol in the tank; our RaceROM self-adjusting flex-fuel does it all for you. Just fit a CANbus enabled Flex Fuel sensor and off you go. Whatever Ethanol content in the tank, the tune will automatically adjust to give you optimal performance. Link up with ECU Connect or use the Sports Display to display the current Ethanol blend. A quick check can be carried out when stationary just by pressing the cruise control button to sweep the tacho needle to display ethanol percentage up to 70%
  • Up to 8 CanBus Inputs
    1. Add a range of external sensor inputs. For example:Zeitronix ECA-2 ethanol sensor
    2. Zeitronix ZT-3 wideband sensor
    3. Innovate LC-3 multi-sensor
    4. ECUmaster CANswitch
    5. Autosport AnalogX
    6. Custom user-defined CAN sensor
  • CAN devices such as the AnalogX allow for multiple variable inputs that can be used to import 0-5v sensors, driver trim switches or even a combination including a 0-5v ethanol content signal.
  • Up to 8 CanBus outputs
    • Add external drivers or controllers for boost solenoids, water injection, nitrous control, and even secondary port injection. 
  • Sports Display HiJack
    • Display and adjust your max torque using the sports display or use it as an additional dashboard display to show ECU parameters.
    • RPM limits for each map switch mode can be displayed on the Rev counter display
  • Valet Mode
    1. Low power mode with reduced torque together with a time and distance limit giving you peace of mind when the car is in someone else’s hands. Arms and disarm using steering wheel controls or via the ECU Connect app.
  • ECM and TCM Logging
    1. Log the ECM and TCM simultaneously using ECU Connect
