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.

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.
Vehicle speed that must be exceeded for AutoBlip to be enabled.
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.
The Auto Blip feature is activated when all of the following conditions are met:
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:
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.

As the Flat Foot Shifting feature activates, a temporary rev limit is set that is slightly higher than the current RPM. The ignition timing is retarded by a specified amount that reduces engine torque while preventing the RPM from rising too rapidly. When the driver completes the gear change, the temporary rev limit and timing adjustment are removed.
The Flat Foot Shifting Feature is cancelled when one of the following conditions occurs:
An AFR adjustment is provided that allows you to enrichen the mixture during the shift. The richer AFR cannot be measured from the exhaust gas due to the operation of the rev limiter.
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
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.
The Launch Control feature limits maximum RPM during launch to help control wheel spin and allow the fastest possible take off.
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:
Set the launch control rev limit as follows:
(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 that the launch RPM is below the stall speed of the torque converter.

The Map Switching feature is enabled by the option buttons in the ‘Map Switch Options' map. Four modes are allowed by default, but this can be reduced if desired. In “Mode 1”, the ECU will use the original ECU maps for Fuelling, Base Ignition Timing and Ignition Advance. In the other three modes, the ECU will use the new Fuel, and Ignition Timing maps labelled Mode2, Mode3 and Mode4 as appropriate.
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. |
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.
When this option is selected, the ECU maps are selected depending on the vehicle's traction and stability settings.
When this option is selected, the ECU maps are selected depending on the Automatic Transmission setting.
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.
