Do Not Buy!!
Getting a hold of the seller is nearly impossible. Any attempt at communication involved extremely long waiting periods, and I was never given clear or useful guidance on how to properly install the software required to use this product. The seller sent an additional USB that was supposed to contain the software, but the USB did not include the main application needed to make the unit function. I spent countless hours troubleshooting on my own, including reading the provided CD on a different computer, transferring files to the USB, and then attempting to install everything on the intended computer. Despite all of this effort, the software still would not install or run. I searched forums, checked websites, and followed every available resource I could find, with no success. There was no clear documentation, no reliable installation instructions, and no meaningful support from the seller. At the end of the day, without functioning software or proper support, this product is completely unusable. Unfortunately, this turned into a very frustrating and time consuming experience, and I cannot recommend this product based on my experience.

Not compatible with all ecu's
Functions, but can't write chipset TC1762. Protocol only reads 1766 and above. Separate power supplies won't work and also, trying to update the clone is a big no no. Many who done it says it works, but never have the files for the update online.
