Introduction

EcuTek RaceROM is a package of special software features that can be installed into the ECU of the supported vehicles. You simply open your ECU ROM file using EcuTek software, apply the RaceROM Feature File (Patch) to it, adjust the RaceROM maps as necessary, and then program the ROM file into the vehicle.

Please read How to: Add/Remove EcuTek Race Rom to your Vehicle. Feature File Guide for info on how RaceROM works, how to install and uninstall RaceROM feature files, and further hints and tips.

The current RaceROM features are listed below. LIve tuning on VAG products is only set up on RaceROM maps so you CANNOT live tune every map only maps with a RaceROM origin tag.

Please also see our website for various videos and webinars for further information.

RaceROM Map Switching

The Map switching function has been updated to deliver individual Map switch mode

• Lambda Target Maps

• Ignition timing Maps

• Boost limit Maps

• Torque target

• Rev Limit

• Vehicle Speed limits

These are covered in the individual section below, when the flex fuel feature is introduced there will be adjustment maps for each mode as well.

Boost Target Max mode 1-4

These maps are a boost target limit applied to the OEM value of boost target derived from the torque-> load -> torque functions () and limit the set value down to the output of this map. Be aware that in some circumstances limit boost may effect the torque target as well due the the OEM control function incorporating the operating targets into the base calculations.

Open

Torque demand Limits

Per Gear per MS Mode Torque Demand limits are available in the torque control category to limit the maximum torque demand in both Sport and Normal to allow for fine tuning of drivability in each mode.

Open

Accelerator multipliers are also available to adjust the accel pedal scaling of the torque demand limit

Reference Airflow

Per MS mode airflow limitations can be applied using the Reference Air charge Limitation maps, this could be used to control the reference airflow per gear and RPM lowering power output when required.

These maps use RPM and gear to cap the reference aircharge.

Map Switching EA888 specifics and Steering wheel buttons/Cruise control stalk operation.

For Map Switching and RR controller on Skoda, Audi and Seat MQB Simos 18 models with a cruise stalk setup, there are different procedures to follow vs Volkswagen Golf models with a steering wheel buttons.
Map switch operates the same for both versions.

Enabling Map switching is a simple as selecting the number of modes you wish to use and then populating the MS mode maps that you need to tune. Map Switch mode descriptions for ECU connect can be used so the car owners using the ECU connect App know what each MS mode is tuned for e.g. 91 octane, 95 octane and e30.

Enable using the Map Switch Modes Enabled checkbox, by default 4 MS modes are selected.

RaceROM Power and Torque Controller

As per the previous versions of RaceROM the RaceROM torque and power controller are configurable in the software to limit the torque and boost infinitely by the car owner. It also display’s the current setpoint on the Sports display and ECU Connect App.

The RaceROM controller needs to be enabled to limit (CAP Only) the maximum boost and torque targets using the cruise controls

RaceROM Controller Boost Default

Is the value that the controller will reset to after a battery reset, the Max and Min set the limits for boost targets

RaceROM Controller Boost Max & Min

RaceROM Controller Torque Default

Is the value that the controller will reset to after a battery reset, the Max and MIn set the limits for Driver torque demand.

RaceROM Controller Torque Max & Min

RaceROM Sport Displays

It is possible to set up the sports displays (of vehicles equipped with them) to display almost any variable. This can also be changed by the car owner using ECU connect pages. to configure what can be displayed on the sports display use the following maps

there are two display modes,

• During map switching only (so only when you are changing the RR controller using the cruise buttons to adjust the controller)

• During Normal Operation, this mode overwrites the value full time (except when map switching)

Each Display mode can have individual inputs specified using the Sport Display Options Maps

Sport Display Options (during Map Switch)

This map sets the parameter that you want to display on the gauge when you are using the Map switch change menu.

if you have the RaceROM Controller setup to control Torque or Boost it is recommended to set these as RR controller input to display the setpoint on the gauge, if there is no gauge the RR controller setpoint can be viewed in the logging under

If you want to display something else like Knock retard Average or Lambda target these need to be input into a custom map and then this custom map set up as the the display variable .

Note - the scaling output of the map should suit the sports display max and min, the display cannot process negative values and strange values will display if negatives are used.

Sport Display Options (Normal Operation)

This is the normal Display map that control the sports display values under normal operation

As per the above example custom maps can be used to display any value custom maps can recieve.

Sports Display AutoScale Maxium & Minimum

These are the values that the sports display will scale between

Sport Display Ranges (normal and Per MS modes)

these maps control the maximum value that the gauge will display this is helpful to stop wrap around if putting custom map inputs into the sports displays.

ECU Connect Pages

ECU Connect pages can be disabled in the ROM if they are not required, ECU Connect pages allow the car owner to adjust what is displayed on the sports gauges from within ECU Connect

In ECU Connect to access the ECU Connect pages from the My Car Menu select Sport Display Set up

From there select the gauge you wish to alter

and Choose the variable you wish to display

and watch the Sport display change to show the desired variable, the “Tuner” option displays the selection you as the tuner have setup in the normal mode display overwrite, the settings above make a sports display like below.

Boost Control (Simplified Wastegate Control)

With the introduction of RaceROM v3 the ea888 platform now has four Map Switch Mode boost limits and the option to switch to a tradition WG duty style map

Simplified / Traditional WGDC control

The Simplified WG control maps replace the factory code using the two turbine model maps based on intake/exhaust pressure flow making it far simpler to understand and tune the base WG setpoint. This map uses RPM and Pressure Upstream of Throttle Set Point (PUT SP), replacing the two turbine model maps based on intake/exhaust pressure flow factory. (user selected to use OEM or RR version).

To enable this feature check the Use Simplified /Tradition WGDC Control check box in RaceROM special features.

Custom maps can also Drive WG output if the CM output is set to either Boost Pressure actuator setpoint or WG position.

Limiters

Several Map switch mode dependant limiters have been added to the RaceROm patch which allow more accurate control over select parameters.

these require enabling in RR special Features to be used simply check the box to enable the maps.

Map Switch mode Adjustable limit map include

A rev limit top value being Mode 1 bottom value mode 4

An Adjustable vehicle speed limit top value being Mode 1 bottom value mode 4

There are also torque and load limits that are covered in the torque and airflow descriptions of these instructions.

Fueling

As part of the RaceROM map switching function We have replaced the OEM maps with map switch versions that are tuneable Lambda target maps for

• Full load enrichment Lambda Target

• Base HDPI Lambda Target

• Base MPI Lambda Target

Lambda Base HDPI Setpoint (RaceROM)

The SIMOS 18.X ECU’s have two separate targets for Direct Injection and Port Injection, we have replaced these map with map switch these two maps are blended together to develop a lambda set point mean value. These maps should be set to match your desired lambda target in normal operating conditions.

Lambda Full Load Enrichment maps

Full load enrichment is active when the Fuel Load enrichment thresholds are exceeded, all of these maps must be exceeded before full load enrichment starts.

The map that is usually calibrated to stop the trigger until WOT is Pedal Threshold for Full Load Operation.

The Full load Enrichment maps are listed below

There are two sets of maps normal and IAT compensation, one for normal IAT and one that is used when the intake air temperature is above the Lambda at Full Load IAT switch Point (an OEM map normally set at 60degC).

These map are RPM and time at full load based. Set these values to represent your target lambda at WOT.

The Lambda Target systems follows this basic flow diagram, where it selects between

Please note that RaceROM maps overwrite the OEM maps so tuning changes should only need to be made to the RR maps. Custom maps can also alter the Lambda Target.

Fuel System

Injection Quantity adjustment (via custom maps) can be made, in the future when a flex fuel feature is integrated this section will be populated.

PFI Size

To scale the Port Fuel Injectors on the Vehicle a RaceROM version has been added to match the normal injector flow rate in CC/min.

The default Value is 200cc based on the known injector size of EcuTek’s development car, use the manufacturer guide as a base and correct this value to keep the trims tight when using PFI.

Ignition Timing

RaceROM Ignition timing maps for Lift and No lift (as Previously mentioned Consolidation of 18 ignition maps for low flap, into just 1 lift and 1 no lift map per mode (OE maps not used).

These maps emulate the OEM maps which would no longer need to be tuner the RaceROM ignition maps can be live tuned as required.

Ignition Timing Mode 1-4 & Lift

These base setpoints still have knock correction and other corrections applied and the values are only applied when at higher load points when the low load tuning is required the OEM maps will still require tuning.

Live tuning (RaceROM maps Only)

We have added the ability to live tune RR maps (and only RaceROM maps at the moment) so you can tune any 2D or 3D RaceROM map including custom map values help to tune you boost and timing a little quicker. for more details on how to utilise RR live tuning see the following article

Immobilizer off

As an option for engine swap vehicles. to disable the immobiliser to use an engine in an engine swap simply set the checkbox and program the ECU

Custom maps

Maps that are blank that you can configure to your liking to do anything you required and to make features like Adjustable Launch control, rolling launch, nitrous, Meth and fuel quantity and timing adjustments for alternative fuels.

Activation using any

• Map switch mode

• Input Parameter

• Cruise Button

Axis interpolation methods adjustable between interpolate (normally), HI low and nearest.

Output calculation for replace, Multiply, Add, cap value HI & low as well as Multiply and Add to integral (with limits)

 For more information on how to tune using custom maps please see the link .

CAN inputs

Take any Can based input (some defaults exist) and use it in custom maps to give the output you want. ( ) there are more instructions on how to set up can inputs here .

On our dev MK7.5 GTI we used the sound control module CAN wiring under the scuttle panel to wire in various inputs. Please note wiring to the OBD port will not work as the gateway module will filter out the CAN Communication and it will not make it onto the powertrain CAN bus.

CAN outputs

Drive an external can based device for external WG, meth controllers or nitrous, see for instructions to enable the output and CAN bus wiring. Devices like this could be used to drive a high current PWM output.

Please note wiring to the OBD port will not work as the gateway module will filter out the CAN Communication and it will not make it onto the powertrain CAN bus.

Valet Mode

Torque, engine speed, vehicle speed and distance limited valet mode, with a tell-tale indicator on Golf model cars.

To enter valet mode these are the set’s

1. Press “Res” button to enter MS mode choice,

2. Press “+” to get to mode 7 (7Krpm on dash)

3. Press “Res” when it displays Mode 7, the Coolant Temp Gauge should go to max now to show you are in Valet mode

4. There will be a torque and speed limits applied now, they will reset on Key off.

To exit valet Mode

1. Press “Res” button to enter MS mode choice,

2. Press “+” to get to mode 7 (7Krpm on dash)

3. Press “Res” when it displays Mode 7, the Coolant Temp Gauge should go to normal now to show you are NOT in Valet mode

4. There will be NO torque and speed limits applied now.
