Show original supplier description
The JHM Power Connect ECU & TCU Flashing Cable serves as a crucial USB to OBD2 interface for your vehicle's Engine Control Unit (ECU) and Transmission Control Unit (TCU). By utilizing this cable and the corresponding software, users can unlock enhanced horsepower, torque, and improved shifting performance. The product is specifically noted to be for B7 TCUs only. For all B7, B6, B5, and C5 ECUs, a different 'OLDER TUNING' cable is necessary. However, for all B8, C7, D4, C6-A6 3.0t, 4L Q7 3.0t, C6-S6 V10, D3-S8 V10, and newer ECUs and TCUs, this Power Connect cable is the sole requirement for flashing both the ECU and TCU. The cable is compatible with various Audi and Volkswagen models, with specific fitment details often requiring user verification as the retailer may not list all compatible vehicles. It is important to note that this product is intended for "Off-road use ONLY" and "Racing Competition Only." It is not legal for use in highway or street vehicles. Users must purchase tuning software separately from JHM's website. The product includes various components that are "NOT FOR PUBLIC SALE" as they are part of a bundle. Additionally, the product may contain chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
