Terms of Service

Last updated: September 9, 2026

1. Acceptance of Terms

By accessing or using PulseWidth software and services ("Services"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these terms, do not use our Services. These Terms constitute a legally binding agreement between you and UBT Performance, LLC, doing business as PulseWidth Tuning ("Company," "we," "us," or "our").

2. Description of Service

PulseWidth provides advanced calibration, diagnostic, scanning, logging, data-acquisition, and ECU-flashing software and related services for Subaru vehicles. The Services are intended for trained users and automotive professionals who develop, validate, restore, or maintain lawful emissions-compliant calibrations and for other independently lawful applications. The Services do not certify any calibration, vehicle, part, or configuration, and training is not an exemption, approval, or legal safe harbor.

3. Global Emissions Compliance (CRITICAL)

IMPORTANT: The United States Clean Air Act (42 U.S.C. § 7522) and emissions, anti-tampering, type-approval, inspection, registration, import/export, and road-use laws in other jurisdictions may prohibit modifications to motor vehicle emissions control systems. By using our Services, you acknowledge and agree to the following:

3.1 Federal Prohibition: It is a federal violation to manufacture, sell, offer to sell, or install any device or software intended to bypass, defeat, or render inoperative any emissions control device or system installed on a motor vehicle used on public roads.

3.2 No Defeat Devices: PulseWidth software is NOT intended to be used as a "defeat device" as defined under the Clean Air Act. We do not sell, provide, or support any calibrations or modifications designed to defeat emissions control systems on vehicles used on public roads.

3.3 User Responsibility: You are solely responsible for ensuring that any modifications you make to your vehicle comply with every law that applies where the user or vehicle is located, registered, modified, operated, inspected, sold, imported, or exported. Violations may result in substantial civil penalties, criminal exposure, loss of registration, and other remedies; penalty amounts change over time.

3.4 No Automatic Competition Exemption: Labeling a vehicle or product "competition only," de-registering a vehicle, or signing a competition agreement does not by itself create a Clean Air Act exemption or authorize tampering. If you contend a use is lawful for competition, you are solely responsible for obtaining qualified legal guidance, proving that status, and ensuring the vehicle:

Is used exclusively for sanctioned competition events
Is never operated on public roads or highways
Has been de-registered for street use
Is documented through our Competition Use Agreement

3.5 Disclaimer Insufficiency: You understand that "for off-road use only" or similar disclaimers do NOT provide legal protection if products are used on, or likely to be used on, vehicles operated on public roads.

3.6 California (CARB): If you are located in California or your vehicle is registered in California, additional restrictions apply. Emissions-affecting aftermarket calibrations and configurations may require a valid California Air Resources Board Executive Order or another independently established legal basis before street use. An EO applies only to its exact approved configuration; PulseWidth does not represent that user-created files are approved.

3.7 Platform Prohibition: You agree NOT to distribute, share, sell, or upload any tune files, calibrations, or modifications through our platform that are designed to defeat, bypass, or render inoperative emissions control systems on street-driven vehicles.

3.8 International Markets: Canadian, European Union/EEA, United Kingdom, Australian, New Zealand, Japanese, and other national or subnational requirements may apply. A ROM's USDM, JDM, EDM, ADM, SADM, or AUDM label does not determine legality and may not be used to evade the law of the place where the vehicle is registered, modified, operated, inspected, sold, imported, or exported.

3.9 No Transfer of Company Duties: Your training, opt-in, assumption of risk, competition declaration, or indemnity does not legalize a prohibited use or transfer away any independent legal duty that applies to Company.

For complete information, please review our Global Emissions Compliance Policy.

4. User Responsibilities

You agree to:

Use the software only on vehicles you own or have explicit written permission to modify
Comply with all applicable local, state/provincial, federal/national, supranational, inspection, registration, import/export, and road-use laws regarding vehicle modifications
Understand that ECU modifications may void manufacturer warranties
Inspect, validate, and accept full responsibility for every calibration, command, file, and flash you select or apply, including resulting vehicle, ECU, engine, drivetrain, electrical, property, or equipment damage
Accept responsibility for fines, penalties, inspections, registration consequences, claims, and other legal consequences arising from your modifications or use
Not use the software to create, distribute, or apply emissions defeat calibrations to street-driven vehicles
Complete and submit a Competition Use Agreement before applying any emissions-affecting modifications to a competition vehicle
Not reverse engineer, decompile, or create derivative works from our software
Not share your account credentials or license with others

5. Licensing

PulseWidth software is licensed, not sold. Your license grants you the right to use the software according to your subscription tier. An unbound license may be transferred only through an official Company process where offered; a bound vehicle/file-identity license cannot be transferred. Licenses may be revoked for violation of these Terms.

Permanent vehicle/file binding.

When a vehicle license is bound to the vehicle's protected original file identity, that binding is permanent. From that point the purchase is non-refundable and non-transferable, except where applicable law requires otherwise. Returning the ECU to stock, removing features or ECU Protection, selling the vehicle, replacing equipment, closing an account, or uninstalling the software does not release the binding or create a refund right. See the Refund Policy.

License tiers and features are described on our pricing page. We reserve the right to modify features and pricing at any time.
