Depending on your vehicle, the installation procedure may require a simple OBDII port connection without the hood of the vehicle ever being opened. This is the most simple installation procedure and available on the majority of vehicles prior to 2010. In certain vehicles, the procedure may involve removal of the factory ECU to be flashed using our specialized dealer tools and may take around 2 hours to complete. In this case, no soldering or removal of chips from the ECU is required, and all of our software is installed on the OEM factory ECU. Certain ECU revisions may require additional installation steps to be performed and your Unitronic Authorized Dealer will inform you along the way.
In specialized cases involving custom tuning requests, a Unitronic Shipping form and delivery of the ECU to Unitronic Headquarters in Montreal is required. For more information regarding this procedure check out our FAQ, call our offices for more information, and check your specific vehicle model to see if these options are available to you.

This warranty does not cover any ECU parts, any mechanical issues or defective components unrelated to software installation. Unitronic reserves the right to refuse any warranty claim if problems arise from improper installation, misuse, or abuse. Further, Unitronic reserves the right to inspect the ECU for evidence of tampering or misuse. If such is the case, the claim may be denied. If a manufacturer's ECU update overwrites the Performance Software, Unitronic and its dealers will happily reinstall it for you. In such a case, installation charges may apply and may vary between dealers.
For more information please visit our website or contact our Head Office at 1-866-341-2447. Unitronic reserves the right to refuse any refund claims if the request is judged to be inappropriate or dishonest.

Unitronic Performance Hardware products are backed by a limited-lifetime warranty to the original owner/purchaser against manufacturer or craftsmanship defects. In the unfortunately circumstances that you must take advantage of this warranty coverage, proof of original purchase from Unitronic or an Authorized Unitronic Dealer must be provided. Some products require professional installation and therefore installation must be performed by a Unitronic Authorized Dealer or equally qualified professional VW/Audi specialty workshop to qualify for warranty coverage. Please contact Unitronic for more details.
Warranty coverage may be excluded if installation was not performed by Unitronic, Unitronic Authorized Dealer or other certified VAG specialty mechanic, or if product was modified, installed improperly, or used in any way, not intended by the manufacturer. This warranty does not cover labor, consequential damage to vehicle or vehicle components, shipping costs, loss of use of vehicle, loss of time or revenues, or other incidental damage or loss of use.
Product usage in Motorsports may result in denial of warranty claim, as operating conditions are inherently abusive in nature and fall outside of normal operating conditions. Upon verification and acceptance of warranty coverage by Unitronic, Unitronic will repair or replace the defective product. Unitronic reserves the right to accept or deny warranty coverage at their full discretion. Warranty claims must be submitted to Unitronic within 48 hours of product defect.
