If the firmware was changed, do a new stock read out and we will provide you with a updated tuned file. In the event this happens, we cannot be held responsible and there may be costs involved at your expense. Your vehicle will not start and you may have to have your ECU repaired or replaced. Doing this will corrupt the ECU because of the mismatching firmware. ***Important note after you flash вЂ“ After you have received your tuned file and loaded to your vehicle, if you have had your vehicle serviced and the firmware updated during this time, whether you are aware or not, DO NOT flash your car again. To unlock it you will have to run this xdcode.exe application (only once) to adapt the cable to the new required coding. Once that is done close the flash client and then launch the xdcode application below.

The update will cause the device to lock itself. When running the new version for the first time, the firmware will be updated automatically. Launch the flash client and click the next buttons till it errors out because of the driver security. If you bought your flash after 2015, you do not need to do this. *** Important for 2015 and onВ вЂ“ If you bought a ECU flash previous to 2015, your cableВ hasВ new security features.

You may also have to install the driver separately. If you have errors related to the USB Device, follow the instructions below and try to disable the driver signature. Installing this software is the same as installing any WINDOWS application. This is the responsibility ofВ YOU, theВ customer. We have NO control over this or a way of knowing if your ECU has been flashed previousВ to yourВ purchase. We will then fix your ECU to work with the cable and return it back to you. The only way to read out the ECU and fix this issue is in boot mode on the bench. Even if the ECU was flashed back to вЂњstockвЂќ by these companies, the ECU still cannot be read. Some companies do things to the ECU processor that will not allow it to be read out via OBDII. ***********Attention!!! If you are NOT the first owner of yourВ vehicle, it is possible that your vehicle could have been flashed previously. DO NOT DOWNLOAD ANYTHING UNTIL YOU HAVE READ ALL THE INSTRUCTIONS HEREВ and BELOW. Once the cable is locked to your VIN, the cable cannot be refunded either. Any issues or troubleshooting will be handled accordingly until resolved. Please note that once a file is sent, no returns or refunds will be accepted.
