Just wanted to share an issue I am having with my SCT BDX tuner with everyone. I am currently in the process of a new tune with Lund, and in the process went to update my BDX tuner. As it turns out there is an issue with the latest software revision that causes the device to forget the vehicles Firmware. After spending hours on the phone with 3 different SCT Techs, it looks like the only solution is that they are sending me an X4 to restore my PCM to its original tune. I would like to say that the folks at SCT have been very helpful in addressing my issue and they did everything they could to fix this problem. SCT is aware of this problem and is working on a fix. In the meantime, if you are planning on flashing your car, remain on the older version of software or you will be in the same boat that I am. I believe this only applies to the newer devices that have WiFi, but just to be safe, wait for the next round of updates.
