CUSTOM REMOTE TUNING WITH KEITH FIELDS

2022+ Subaru WRX E-Tuning

A custom tune for your VB WRX.

I tune your WRX around its hardware, fuel and the way you want it to drive. Useful response, predictable boost delivery and behavior between full-throttle pulls matter as much as the peak number.

BEFORE ORDERING

Start with the right information.

Vehicle and tuning tools

Send the exact model year, market, transmission, Accessport part number and current map. The VB uses the FA24 engine; support is confirmed for your specific ECU and software. “2022+” does not guarantee every future model year.

Your hardware and fuel

Identify the exact intake and MAF housing, intercooler, charge piping, exhaust, turbo and fuel-system changes. ETS, Perrin and COBB are brands, not complete compatibility specifications: include part numbers and all mixed-brand components.

Logging and mechanical readiness

I confirm the channels and measurement equipment required for your exact setup before logging begins. Include your fuel grade or measured ethanol content and any known faults. A 2018+ model year does not automatically mean no additional measurement equipment is needed.

Known misfires, leaks, warning lights or other mechanical issues need to be disclosed. I may request checks before tuning proceeds. Collect logs only as instructed in appropriate, controlled conditions.

WHAT TO EXPECT

One setup. A clear tuning process.

Setup review: send your vehicle, parts, fuel and goals. I confirm the supported workflow, price and scope.
Invoice and onboarding: pay your customer-specific QuickBooks invoice after approval, then receive instructions.
Log review and revisions: return the requested data and driving feedback in the same email thread. I use that information to develop the calibration.
Completion: follow the instructions supplied with your final file. A base map or intermediate revision is not a completed tune.

Eight revisions for most $400 e-tunes

The included revisions develop the calibration through the agreed datalog process. Downloading a file again does not count as a revision. Hardware or fuel changes, diagnostic work and additional revisions may require a revised scope agreed before work continues. I confirm what your build needs before payment.

Usually same day. Within one business day.

This applies to initial file delivery and each agreed revision once setup approval, payment and all required details or logs are complete. Business hours are Monday–Friday, 8 a.m.–6 p.m. Pacific. Requests outside these hours begin the next business day. Time collecting logs or resolving vehicle issues is separate; this is not a promise to finish the whole tune in one day.

EXPERIENCE YOU CAN EXPLORE

Cinderelli: the orange 2024 WRX

See a documented E70 customer build from my AWD Tuning work. Its fuel and hardware combination is a build example, not an OTS specification or a guaranteed result.

Base map, OTS or custom e-tune?

A $50 base map is a starting calibration for approved use, with scope confirmed first. It is not a finished tune or permission for full-load driving.

$150 WRX OTS maps are in preparation. Planned ETS, Perrin and COBB variants require exact hardware, fuel and transmission specifications before release. They are not available to purchase yet.

A custom e-tune develops your calibration from the agreed logs and feedback. Tell me how you want the car to behave, including response, power delivery and intended use.
