Important – bench unlock required
Please be aware this product will require a bench unlock via the BFlash Tool before a tune file can be programmed in. If you would like to purchase a BFlash Tool or find out which of our tuners can perform a bench unlock for you, please contact sales.
Important – ECUs manufactured after June 2020 cannot be unlocked
Security on ECUs manufactured after June 2020 has been changed and bench unlocking is not possible for them. There are no tuning products in existence that can support these new ECUs.
We are working hard to find a solution to this and nothing is being ruled out as a potential fix.
RaceROM Custom Features
- Four-way Mode Switching
- Swap between four different modes using ECU Connect on your mobile device. For example, Track Mode; Fast Road Mode, E85 Mode; Economy Mode. It’s up to you to decide what set-up you want in each mode.
- Using the RaceROM Boost controller, you can adjust your maximum boost pressure and/or maximum torque in each mode using the cruise control or ECU Connect.
- One-Touch AntiLag/Rolling Launch
- Rolling Launch allows you to roll race at the touch of the button. To set, enter the map switch mode in which Rolling Launch is activated. Press and hold the cruise control set button to build boost, adjust your speed with the accel pedal to match your opponent aaand…release the set button and enjoy! The system can be set up using activation time limits, temperature limits and a minimum re-arm time to maintain reliability.
- RaceROM Burble
- Switch between a range of soft to hard burble on the fly, or even disable completely in Sport for full stealth mode.
- Self Adjusting FlexFuel
- No more worries about calculating the ethanol in the tank; our RaceROM self-adjusting flex-fuel does it all for you. Just fit a CANbus enabled Flex Fuel sensor, and off you go. Whatever Ethanol content in the tank, the tune will automatically adjust to give you optimal performance. In addition, there are fail-safes to prevent engine damage if your sensor fails. Link up with ECU Connect or use the Sports Display to display the current Ethanol blend. A quick check can be carried out when stationary just by pressing the cruise control button to sweep the tacho needle to display ethanol percentage up to 70%
- Up to 8 CanBus Inputs
- Add a range of external sensor inputs. For example:
- Zeitronix ECA-2 ethanol sensor
- Zeitronix ZT-3 wideband sensor
- Innovate LC-3 multi-sensor
- ECUmaster CANswitch
- Autosport AnalogX
- Custom user-defined CAN sensor
- CAN devices such as the AnalogX allow for multiple variable inputs that can be used to import 0-5v sensors, driver trim switches or even a combination including a 0-5v ethanol content signal.
- Fail safe’s can be set up to activate in the event of an input device failure
- Add a range of external sensor inputs. For example:
- Up to 8 CanBus outputs
- Add external drivers or controllers for boost solenoids, water injection, nitrous control, and even secondary port injection.
- RaceROM Sequential Port Injection controller
- Using the Motiv Motorsport Reflex Box, you can bolt on a control aftermarket port injectors, releasing the power from those bigger turbos and fuel pumps to deliver the maximum performance from your modifications.
- Sports Display HiJack
- Display and adjust your max torque using the sports display or use it as an additional dashboard display to show ECU parameters.
- Valet Mode
- Put the car into a low power mode with limited speed and range, either as a security measure or to allow the car to be limited when handed over to a third party. This still leaves all four Map Switch modes available for your choice of setups.
