Open Source E-Tuning
With Open Source E-Tuning, more is required from the customer than E-Tuning with an Accessport. You MUST have a laptop and be able to install the Open Source programs Romraider – for logging and ECU Flash – for downloading and flashing tunes to your vehicle’s ECU. We will provide all the download links and detailed instructions on how to download the programs. Romraider is a free open source program created by enthusiasts like you. The installation process of Romraider is more involved than commercial programs but nothing most people can’t accomplish.
You will also need a wideband AFR gauge like AEM or Innovate. The gauge will need to be wired to the ECU or use a serial adapter to log with Romraider.
Features included for most years:
- E85 Cold Starts: Years of testing to get you a E85 tune you can run year round. We have done testing down to -40deg f to make sure your car will always start when running E85
- 2008+ Boost By Gear: All MT tunes have boost by gear. This helps your car hit close to boost target in all gears
- Smoother boost for more linear power delivery
- High Gear Over-Boost Protection: We employ over-boost protection in 4th-6th to limit boost below defined rpms. An example is if someone goes WOT in too high a gear at too low an rpm, boost is limited to wastegate pressure to keep engine loads low and reduce the risk of engine damage.
- Launch control / Flat Foot Shift: Available for most years
- Speed Density: Available for some years
