Features
Vehicle Compatibility and Return Conditions.
This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.
Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.
Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.
Note on Vehicle Configuration
This listing includes the term "driver" or "passenger". Please note that this may refer to a region specific variation based on vehicle configuration (LHD/RHD) or regional preferences. Much of our database relates to US sourced products where "Driver" typically refers to the left-hand side in LHD vehicles, and "passenger" to the right. In RHD vehicles, this terminology is reversed. Review product details carefully for compatibility. Contact support if you have any questions. StreetFX may not accept returns for special order products.
(keyword: driver)Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations.
