RaceROM Features In Depth

RaceROM Features

EcuTek RaceROM was developed to enhance the standard OEM ECU with additional features. These are some of the features that are implemented in the range of ECU supported by RaceROM.

Currently, RaceROM is available for Subaru electronic-throttle vehicles, Mitsubishi EVO X, and Nissan GTR R-35 ECUs. Other vehicles will be supported in the future.

General RaceROM Features

These RaceROM features are generally available on all vehicles.

  • Map Switching

    Map switching gives you the ability to swap between two calibrations that can be tailored to your requirements. For example:

    • "Road Mode" and "Race Mode", can provide two sets of maps for civilised driving to conserve fuel, and then a high performance calibration for track days or racing.
    • "Valet Mode" A low performance mode if you have to put your car into someone else's care.
    • "Anti-Theft Mode" A mode where the car just doesn't work unless you know how to change maps.

    Switching calibration can be done in several different ways, including whilst driving.

    Each calibration can include its own set of other RaceROM features, such as flat-foot shifting or auto throttle downshift blip.

  • Per-Gear Boost Control

    Per gear boost control allows separate boost calibrations for each gear, thereby maximising boost control options and flexibility. For example, boost may be reduced in 1st gear to prevent wheel spin, but raised in 3rd-6th for increased performance.

  • Per-Gear Rev Limits

    This feature allows per gear rev limits to be configured. It could be used to improve 0-60 times by allowing a higher 2nd gear limit to just hit 60 mph / 100 km/h in 2nd, whilst preserving the lower rev limit in other gears.

  • Speed Density

    The Speed Density (SD) feature changes the way the engine load is calculated. When SD mode is activated, the ECU will disregard the MAF sensor reading and will instead calculate mass airflow based on Engine Speed, Manifold Pressure and Air Temperature. This allows the MAF sensor to be removed, and a larger intake may then be fitted if desired.

    This function can be tailored to work permanently, or under certain circumstances, such as MAP value or MAF voltage, enabling you to make the most of the precision of MAP and MAF fuel calculations for low speed driving.

Vehicle Specific RaceROM Features

These RaceROM features are available for certain ranges of vehicle.

Subaru

  • Subaru: Launch Control

    The Launch Control feature limits the RPM during launch in an attempt to control wheel spin and allow the fastest possible take off.

  • Subaru: Downshift Auto Blip

    The Auto Blip feature applies a short burst of throttle when the driver is down-shifting under braking. This raises the RPM to help provide a smooth entry into the lower gear by reducing engine braking.

  • Subaru: Flat-Foot Shifting

    The Flat Foot Shifting feature allows the driver to up-shift without lifting his foot from the accelerator pedal. This helps to avoid a drop in boost pressure and corresponding loss of power while shifting gear.

Nissan GTR

  • Nissan GTR: Wide Range Boost Limit Maps

    The standard ECU uses 8-bit maps to restrict boost pressure, you can now use 16-bit wide range boost limit maps to increase the boost limit to higher levels.

  • Nissan GTR: Upshift boost spike prevention

    When running increased levels of boost, the ECU can be programmed to maintain a steady boost pressure to avoid boost spikes while changing gear.

  • Nissan GTR: RaceROM Boost Controller

    The desired boost can be controlled using the cruise control switches. The boost setup can be displayed on the GTR's LCD display too.

  • Nissan GTR: MAF Left-Right Swap

    Several aftermarket intercoolers switch the intake plumbing in relation to the standard intercooler. This switches the input from the MAF sensors to ensure correct fuelling to each bank of the engine.

  • Nissan GTR: Large fuel injector support

    Injectors over 750cc are not supported by the original ECU as standard. This enhancement allows the use of almost any size of injector.

  • Nissan GTR: Extra Parameter Logging

    GTR RaceROM enables FlashCAN GTR tuning software to measure & record extra diagnostic parameters not accessable as standard, such as:

    • AFR per bank
    • Boost Error
    • Boost Target
    • Calculated Airflow
    • Calculated Torque
    • Desired Wastegate
    • Engine load per bank
    • Gear
    • Injector duty per bank
    • Knock correction
    • MAF per bank
    • Turbo Dynamics
    • Wastegate

  • Nissan GTR: Visual knock warning

    Shows a visual warning of knock using the dashboard's check engine light.

Mitsubishi

  • Mitsubishi: DTC Enable & Disable

    Diagnostic trouble codes can now be enabled and disabled in the ECU, allowing you to tune further without the ECU going into special conditions.

  • Mitsubishi: Extra Parameter Logging

    Mitsubishi EVO RaceROM enables FlashCAN EVO to measure and log extra diagnostic parameters not accessable as standard, such as:

    • Engine Load
    • Charge Air Temperature
    • Boost

More features are currently in development.
