if you plug your mamba max controller into the PC and click the folder in the castle link program that says software it will tell you firmware= v1.17 or 1.16 or older, The icon on your PC for the castlelink shoud say v3.051 under the castlelink symbol. He is saying the firmware v1.17 has fixed alot of cogging issues and to make sure you are updated to the latest version 1.17. Yes i type too much
