Auto start and sweep
Can the auto start and stop for the logging rpm be separated from the brake control mode rpm?. When they are exactly the same start and stop of the gragh gets a little messy . if the engine has had a chance begin the sweep and the logging stop just before the end of the sweep the gragh will be "cleaner" on the ends. With a water brake using load control the brake is trying to stop the sweep and the logging continues.
it should be set on load control for a water brake and stop logging at what ever stop sweep setting is set at in load control section. control loop setup also has affect when load control or any other type of control is being used, i usually use around 70-80% brake apply at end of my runs, the peak rpm must be reached to end run or it will keep logging.
