Hey everyone!

I installed the MM3 tuner today and I believe it was installed correctly!

I have an error code when selecting the switch button.

Error code 10143.

Does anyone know how to fix this?

The package was sent to me with a manual switch to select power levels but when doing research I have found that the power can be switched on the screen.

Is there a special download I need in order for it to work that way?

Thanks for any help in advance!
