Re: Question About " Open Loop "

"Open loop" simply means the engine control unit doesn't use feedback signals to modify it's behaviour.
Basically it sends instructions to the engine but doesn't modify those instructions based on information it gets back. Usually because the sensors that normally send it feedback are too slow to react in those conditions.

The opposite of open loop is closed loop. This means the controller continually modifies it's instructions based on the feedback from sensors.
