I just finished a CS DME flash with the complete CS drivetrain package this morning, and the entire process was remarkably straightforward. I acquired an ENET cable, connected it to my laptop, and followed the provided instructions. In about 10 minutes, everything was completed. They were also very responsive and helpful with any inquiries I had. I had recently bought the car and unknowingly pushed an available update that erased the previous flash. However, they helped restore the CS flash, and now the car feels just like it did before.
