RaceROM is here!!!


What is RaceROM?

RaceROM is a suite of feature enhancements available for OEM ECUs tuned with EcuTek tuning tools, which offers increased tuning & driving capabilities. RaceROM is available for specific ranges of engine management systems, initially for Subaru electronic throttle (Drive-by-wire) based ECUs.

Why add Features to the Standard ECU?

Without question, the OEM ECU offers the best cold start, driveability and refinement when compared to aftermarket ECU hardware. However, many aftermarket ECUs provide extra (generally motorsport related) features, that many enthusiasts desire. Unfortunately, when replacing the standard ECU with an aftermarket ECU, the refinement of the standard ECU is often lost.

Now with EcuTek RaceROM, this compromise is no longer necessary. By way of a software upgrade to the standard ECU, RaceROM adds many custom calibration options to the standard OEM ECU, offering features beyond the standard fuelling, ignition and boost control, yet retaining its driveability, sophistication and fuel economy.

Below, the features available for each vehicle type are detailed.

RaceROM Subaru

RaceROM for Subaru is available now @ Corten-Miller ! RaceROM currently supports the following features on Subaru Electronic Throttle based ECUs:

Note that due to space constraints within some ECUs, not all features are available on all vehicles. However, all features are available on the majority of ECUs. This is due to the available space within the ECUs code and data storage areas varying from ECU to ECU. 153 Subaru ECUs are currently supported.
