I have successfully gotten into the settings and adjusted the password protected parameters. There’s a pdf posted in this thread that helped me figure it out. Be careful if you mess around and take photos af each screen so you can reset anything tou change. I adjusted my espin sport to have 8 levels of assist. It’s not faster...just more assist levels. There are settings for voltage (don’t mess), tire size, etc. see the pdf. I might adjust tire size to see if i get more speed if the computer think i have bigger wheels.The Tire Size one is supposed to say Wd but shows L J d. The other screen is voltage size (or battery capacity?)... and it looks like Bu0.
Found this manual for Bafang displays:

Does anyone know what these settings do? Thanks in advanceelectricbikereview.com
Since I'm not at my friend's house I can't test this but it does look like you can go from PAS 5 to other levels (3, 7 and 9) once you get into the password protected settings. I think that's also where you can remove the 20mph speed limiter too.
