To the OP...'this' type of controllers are not rocket science these days.
Choices used to be time based, inertia sensed, MC PSI sensed and now
ECU Port based (would assume there is an accelerometer involved and/or
MC PSI sensed via any OEM onboard)
OEM's are mostly MC sensed and multiplexed wit the other computers
on board the vehicle.
Key is how they deal with 'real time' software and how they managed
'master/slave' hierarchical decision trees/logic flow/etc.
Again, if managing an after market brake controller (mainly setting
it up...dialing in all of the various adjustments, etc) is too much.
Then buy a used or new TV that has the integrated brake controller
