Subaru BRZ Toyota FT-86 supports 2012 Subaru BRZ, Toyota FT-86 and the Scion FR-S models, and allows reprogramming of the standard OEM engine management unit. UK, US, European & Japanese vehicles are all supported.

Map Switching

Map switching for the BRZ, FT86 and FR-S provides 4 separate customisable tuning modes, which can be changed on-the-fly by the driver using either the cruise control switchgear, the traction control switches, the defog-switch or the automatic transmission mode switches (only available on models with the automatic transmission).

These modes can be customised to provide bespoke settings such as:

• Valet mode - Limits enabled so that the Engine RPM is limited or the torque is limited.
• Economy Mode - The car is tuned to provide the best fuel economy but with reduced performance.
• Race Mode - High power mode for track use.
• Dual Fuel Mode - Settings for different fuel types such as E85 or high quality race fuel.

The map switching also works with other RaceROM features such as Launch Control, Flat-foot Shifting, Throttle Auto-blip or Speed Density. It can also be combined with RaceROM Custom Maps to enable custom features and functions under certain conditions.

RaceROM Maps

Custom Maps

RACEROM CUSTOM MAPS allow the tuner to modify the behaviour of the factory ECU by inserting additional maps into the ECU's normal calculations.

For example, these can be for parameters such as ignition timing, fuel, boost and VVT, and inputs and outputs can also be re-purposed to measure custom sensors or solenoids not featured on the standard vehicle.

This facility lets you add custom compensations or even completely replace the calculations that are normally used. For example:

• Per gear fuel enrichment factor

• Vehicle speed-based ignition retard

• Torque reduction for engine oil temperature

• Throttle reduction for air-flow

• Torque reduction for wheel-speed differential

• E85 enrichment factor for injection volume

• Custom traction control strategies for wheel-speed differential

RaceROM Custom Maps enables you to repurpose an input sensor and actuator output, allowing you to control devices that aren't provided by the car maker ‒ such as a wastegate purge solenoid or intercooler spray pump ‒ or to read data from a custom sensor such as for charge-air temperature, or sensors for ethanol content (Flex-Fuel).

The accompanying map shows a custom ignition compensation for engine speed and manifold pressure.

 Entire functions can be created by linking maps together such as:

• Boost control and wastegate duty feedback by repurposing the Carbon Purge Canister valve to act as a boost control solenoid

• Enrichment factor for E85 content by connecting a Flex-Fuel sensor in place of the Carbon Purge Canister pressure sensor

Each one of the custom maps can be logged and viewed with the use of the ProECU log viewer.
