This product (flash tool device and electronic tuning file/data) is sold as-is. We offer a 72 hour exchange window (from date the shipment is delivered) on the flash tool device/hardware itself against manufacturing defects (inoperable touch screen, broken screen or cables, etc).
Because with the AutoCal there is no mechanism to ensure that a stock file has been reflashed before unlinking the tool, all sales are final for this product.
