RaceRom Tuning Guide
Accelerator Trim
The Accelerator trim map allows you to adjust the accelerator response by intercepting the accelerator position signal and replacing it with a different value. This can improve drivability in vehicles that do not respond to pedal input in a linear fashion.
Auto Blip Feature
| Note |
|---|
Manual Transmission Vehicles Only |
The Auto Blip feature applies a short burst of throttle when the driver is down-shifting under braking. This raises the RPM to keep the engine operating within its power band and provides a smooth entry into the lower gear by reducing engine braking.
AutoBlip Enable
AutoBlip Minimum Speed
Vehicle speed that must be exceeded for AutoBlip to be enabled.
AutoBlip Pedal Percentage
The x axis is time since Autoblip was triggered (described below). Autoblip ends when the maximum time on the X axis is exceeded. Be careful to avoid using too much Accel at low RPM as this will cause the car to push on aggressively.
How to Use Auto Throttle Blip
The Auto Blip feature is activated when all of the following conditions are met:
The ‘Auto Blip Enable checkbox’ is ON for the current Map Switch Mode
The vehicle is travelling faster than the Auto Blip Minimum Speed
The driver presses the brake pedal, followed by the clutch pedal
| Note |
|---|
I'ts important to push the clutch pedal all the way down relatively quickly, going slowly or only part way can cause the blip to occur when the clutch is still partially engaged causing a lurching motion or potential damage. |
The accelerator blip is immediately cancelled when one of the following conditions occurs:
The driver releases the Brake Pedal
The driver releases the Clutch Pedal
The vehicle speed falls below the ‘Auto Blip Minimum Speed’ The Auto Blip timer reaches the end of the map
When the driver down-shifts while braking, the ECU will blip the accelerator. The amount of accelerator to apply and the duration of the blip is controlled by the ‘AutoBlip Pedal Percentage Map’ as shown in the diagram below, this is a 2D slice through the 3D map.
The BRZ/FRS/GT86 platform have proven to be a platform that takes to flex fuel fairly well, making additional power even without forced induction. While some of the early generation high pressure fuel pumps would begin chirping with or without ethanol, all of them have proven to be compatible with ethanol.
For a complete rundown of the RaceROM Flex Fuel system check out our guide here
Flex Fuel Ethanol Sensor Installation
In order to set up Flex Fuel properly you'll first need to purchase and setup an ethanol content sensor kit. These kits typically include a sensor, module, and potentially replacement fuel lines depending on where it is installed.
After installation you'll need to setup the sensor in the Sensors section of the map list.
FF Sensor Default
Sets an ethanol value the system will revert to in the event that the output goes outside the normal bounds of the voltage (FF Sensor Max & Min). You'll typically want to set it close to what the end user is typically going to have in the vehicle. You'll want to set the value close to the voltage output of e85 if running e85 all the time, close to e10 if they typically run pump gas, or a safe middle value if they go back and forth frequently.
FF Sensor Max
Maximum sensor voltage for the sensor. You'll want to set this to the high end of your kits voltage range which can vary. Common kits use either 4.5v or 5v for the high end, refer to the manufacturer for their recommended values.
FF Sensor Min
Minimum sensor voltage for the sensor. You'll want to set this to the low end of your kits voltage range which can vary. Common kits use either 0.5v or 0v for the high end, refer to the manufacturer for their recommended values.
FF Sensor Scaling
This is where you setup the relationship between the voltage of your sensor and the ethanol content it designates. Most kits output a higher ethanol content the higher the voltage level, refer to your manufacturer for their recommended values.
FF Sensor Smoothing
Applies a smoothing value to your ethanol content values being used by the computer for calculations. Can be helpful to get a more consistent value if the signal you get from your sensor tends to have small spikes.
FF Sensor Source
Selects what input is being used to add ethanol content to the vehicle. Keep in mind that this will also require deleting whatever sensor was previously on that channel, so check local laws for legality and make sure to adjust the tune correctly to prevent any issues.
Launch Control
The Launch Control feature limits maximum RPM during launch to help control wheel spin and allow the fastest possible take off.
How to Activate Launch Control
Ensure the ‘Launch Control Enable’ checkbox is ON for the current Map Switch Mode
Engine must be running and Vehicle must be stationary
Press clutch pedal and move the gear stick to 1st position
Quickly press the accelerator all the way to the floor
Adjust launch RPM using the cruise control stalk
Release the clutch to commence launch
When Launch Control is active, the rev limit will be set to the ‘Launch Control Rev Limit’. This limit defaults to the
'Launch Control Rev Limit Base" value and can be adjusted up and down using the cruise control stalk. Select "Res/Acc" to increase the launch RPM and "Set/Cst" to decrease it. An alternative method of adjustment is available for vehicles without cruise control.
During the launch, the rev limit increases according to the 'Launch Control Rev Limit Delta, This 2D map, indexed by elapsed time, has multiple columns to allow you to set up a multi-stage system for best results.
Adjustments are provided that allow you to richen the AFR and retard the timing when the vehicle is stationary in order to create pops and bangs. This adjustment is removed as soon as the vehicle starts to move.
The Launch Control feature is deactivated when one of the following conditions occurs:
The elapsed time exceeds the last column on the ‘Launch Control Rev Limit Delta Map’
The driver lifts off the accelerator
The driver performs a flatfoot shift
How To Adjust Launch RPM Limit
Vehicles without cruise control
Set the launch control rev limit as follows:
Ensure the ‘Launch Control Enable’ checkbox is ON for the current Map Switch Mode
Engine must be running and Vehicle must be stationary
Turn on rear window demist switch
Press clutch
Rev engine and hold at desired launch RPM
Turn off rear window demist switch
Check engine light will flash to indicate that new limit has been saved.
Vehicles with automatic transmission
(Due to the operation of the automatic transmission, we do not advise you use the Launch Control feature) Activate the launch control as follows:
Ensure the ‘Launch Control Enable’ checkbox is ON for the current Map Switch Mode
Engine must be running and Vehicle must be stationary
Press brake pedal and move the gear stick to a forward drive position
Quickly press the accelerator all the way to the floor
Adjust launch RPM using the cruise control stalk
Release the brake to commence launch
Ensure that the launch RPM is below the stall speed of the torque converter.

Currently, the ECU does not always remain in the chosen mode when the ignition is turned off. We hope to develop a solution to this problem. In the interim, you should always check the current mode when starting the vehicle.
For RaceROM v13 onwards on BRZ and BRZg2/ GR86 mapswitch mode should be properly saved, please contact Ecutek support if you are having trouble. |
Switching mode using the cruise control stalk (BRZ g1)
Ignition must be ON
Ensure cruise control master switch is OFF
Pull the cruise lever towards you (i.e. cancel position) and hold for 1 second.
The tachometer will move to 1000, 2000, 3000 or 4000 rpm to indicate the currently active mode.
Move the cruise lever up (res/acc position) to increase the mode.
Move the cruise lever down (set/cst position) to decrease the mode.
Save the selected mode by pulling the cruise lever towards you (cancel position) or waiting 3 seconds.
Switching mode using the accelerator and defog switch
The driver can switch modes by turning on the rear window demist switch while holding the accelerator to the floor. Every time you do this, the mode increases by 1. After mode 4, it goes back to mode 1.
The check engine light will flash to indicate which mode has been set: One flash for mode 1, two flashes for mode 2, three flashes for mode 3, etc.
Switching mode using the traction and stability control switches
When this option is selected, the ECU maps are selected depending on the vehicle's traction and stability settings.
Mode 1 - Traction Control on, VSC Normal
Mode 2 - Traction Control on, VSC Sport
Mode 3 - Traction Control off, VSC Normal
Mode 4 - Traction Control off, VSC Sport
Switching mode using the Automatic Transmission Mode
When this option is selected, the ECU maps are selected depending on the Automatic Transmission setting.
Mode 1 - Normal
Mode 2 - Sport
Mode 3 - Snow
Mode 4 - Manual
Integration with Launch Control, Flat Foot Shifting and Auto Blip
The Launch Control, Flat Foot Shifting and Auto Blip features can be independently enabled in each of the four modes.
Logging
The “Mapswitch Mode” diagnostic parameter can be used to log the current map switch mode.
