Howdy. It's not a stunlocker thing, but I've cracked my ep801. I used e-max tuning. They haven't yet released software for the ep801 but offer a personal service done remotely. Best 119 euros I've spent in a while. I needed to get my hands on a Shimano dongle to connect to my p.c. but they did the rest. Few emails, sent some screenshots of my bike connected to their software, made and appointment and Markus did the rest. I now have a bike derestricted up to 50km/hr, accurate speed and distance readings on the display, and the license to use on my bike as often as I need to once they release the new software. I'm really impressed and highly recommend doing it.
