Hi All,

I was programming my Em 50-4 controller yesterday to remove the RPM limit on a Fly 10 Ebike. It seemed to work well. I took the HDC on page 2 from 680 to 2000 and my top speed went from 32 to 38 mph. I went in today to mess with the settings a bit more to see if I could get the 3 speed switch to get me to street legal and then this new top speed.

But now the display is throwing a "controller failure" message and showing a voltage that is way too high. Did I brick it? Here's a potato video of the settings.


If I did brick it, are there any better places to purchase the same controller than aliexpress? Should I just move to a different controller?

Thanks!
 
take FarDriver and don't stress. I had Votol, 50x4, em80 - I threw everything away! Now I have 72360 and 72260 - and my head doesn’t hurt
