Hey billynomates, welcome to the forum.
In this thread https://forum.openmarine.net/showthread....70#pid9170 there's a motor.ino with IBT-2 specific adaptations. The motor.ino code has since then been updated, but the version given here might still work for you. Otherwise, you could get an old version of motor.ino from github and diff against that, so you can isolate those specific adaptations, and then apply them to a current motor.ino.
