Your Subaru.
Your next step.
I’ve been tuning since 2005. Choose your WRX or STI below for a custom tune built around your hardware, fuel and the way you use the car.
Most custom e-tunes are $400 with eight revisions. Compatibility and scope are agreed before payment.

2015–2021 WRX / FA20
VA WRX e-tuning for your specific combination. Confirm hardware, fuel, device and logging needs before ordering.
2015–2021 WRX e-tuning details →2002–2014 WRX & 2004–2021 STI / EJ
EJ Subaru tuning with specific preparation and wideband datalogging guidance. Discuss your current flex-fuel hardware and calibration before making changes.
EJ WRX & STI tuning details →BRZ / EcuTek
BRZ uses a separate service route. Explore first- and second-generation tuning and confirm your exact ECU and licensing needs.
BRZ EcuTek tuning →What does an e-tune involve?
We confirm the vehicle’s configuration and mechanical readiness, agree on scope and payment, then work through the requested datalogs and revisions. Your feedback on response and drivability is part of the process.
Send the model year, transmission, market, modifications, fuel, device details and current concerns. If you use EcuFlash, RomRaider or Atlas, tell me your ECU/ROM and interface so I can assess support.
A wideband display alone does not establish loggable mixture data. Use your generation’s guide to review the equipment needed for your setup.
Request a Subaru setup review ↗Before you order.
Is a custom e-tune the same as an OTS map?
A custom e-tune is developed through the agreed logging and revision process for your vehicle. An OTS map is intended for a specified combination. Planned WRX OTS maps are $150; availability and exact fitment must be confirmed.
Can I buy a base map first?
The $50 base map service supplies a starting calibration for approved use and an agreed combination. It is not a completed custom tune; follow-up work is scoped separately.
Can I book a dyno session instead?
Yes. Send your location and facility details to discuss an in-person session or worldwide travel tuning.
