Did you change out the throttle? I had the same error on my M20, bought a < $20 throttle on Amazon and it completely fixed the problem. I did have to make a gender changer adapter and swap the signal/ground wires on the adapter I made to get it to work though. They definitely don't go out of their way to make it easy for you to use 3rd party stuff, but if you know how to solder it's no big deal.
That thing has been giving you fits!
I have a 3rd controller coming for my aniioki. Frustrating but good customer service so hopefully this one works.
