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:
- 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
- 2008+ High Gear Over-Boost Protection: We employ over-boost protection for 5th & 6th gear in 6speeds and 4th & 5th gear in 5speed, 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

Johnny –
I was online looking for an E-Tuner to help Tune the ROM for my STi Hawkeye after modifications I installed for more torque and horsepower and purchased a Stage 3 E-Tune from JM Automotive . I really appreciate everything JM Automotive has done for my 2.5L turbo charged 2006 Subaru Impreza WRX/STi 6-spd MT . The Engine Calibrator was wonderful at reviewing logs I sent for review, that were filed using my laptop which I emailed each time after flashing a new revision . JM Auto emailed me updated Revisions each time with needed adjustments till we got to the most reliable power band achievable. And took the time to explain things to me that I did not understand ,I’m very satisfied with the outcome of the Stage 3 tune I purchased. The STi now has unimaginable power gains ,feels great to drive with all the extra powerband I gained with the E-tune ,this was my first E-tune and Devin simplified everything from start to finish , this was an experience I will never forget . I would definitely use the E-tune service they provide again.
