5 Unichip Warranty Information For 90 days following the original owner s purchase of a Unichip, Unichip of North America (UNA) warrants no other ECU product generates more power from a specific gasoline engine than a properly functioning, custom tuned Unichip in the specific vehicle for which it is tuned. If another ECU product generates more power from that engine within 90 days of the original owner s purchase of the Unichip, then UNA will refund original owner the cost of all UNA parts, UNA installation, and UNA tuning. Shipping, testing, dynamometer costs and the cost of removing any UNA parts are specifically not covered by this warranty and will not be refunded to the owner. To claim a refund, owners must provide dynamometer proof another ECU product produced more power when installed on the specific vehicle and that vehicle and all of its parts were in an identical condition other than the ECU enhancement. Three dynamometer tests must be performed using the Unichip and three tests using the other ECU product. The average of the three tests performed on each product shall constitute that product s score for determining power. The same technician, using the same dynamometer in an identical condition with the same settings, must perform all test runs. All environmental conditions including temperature and pressure altitude and the vehicle s cooling system temperatures and drive train temperatures must also be identical for all six runs. The vehicle must also use the same fuel for all six tests. UNA reserves the rights to, at UNA s exclusive discretion, re-tune the Unichip involved in a performance warranty claim at no cost to the customer making the claim or to provide a warranty refund; if after a retune, the Unichip still makes less power than another product, UNA will provide a refund IAW this warranty statement.
