We offer unique tunes for a variety of vehicles running Subaru EJ25 engines.
This tune requires you to have access to flashing equipment and software.
How It Works
Send us a complete list of all vehicle modifications, ECU model, your current tune, and datalogs of various driving conditions with the following minimum parameters logged:
- Engine Speed (RPM)
- Vehicle Speed (MPH/KPH)
- Manifold Pressure
- Calculated Load
- AFR (wideband preferred)
- Feedback Knock
- Knock Learning (or “Fine Knock Learning”)
- MAF Voltage
If you do not send us complete logs, we will ask that you fix any issues and try again.
Once we receive all of your files and vehicle specifications, we will update your tune and provide you with the new file. If you need another update for things such as new components, you will need to purchase this service and provide the same information again.
If you have any questions, please CONTACT US!
