Disable Closed Loop effectively changes the engagement RPM to an RPM that should never be reached. This keeps operation in open loop all of the time. You can also adjust the engage and disengage RPM to your liking.
Target A/F is the base air/fuel target. This can be overridden with the closed loop target and limit tables
below, which are based on temperature.
WOT Based On MAP Only will use the WOT MAP Based Engagement table to depict when the ECU transitions from closed loop to open loop. Above the manifold pressure threshold in mBar it will go open loop.
Open Loop engagemet is generally based on TPS for most applications by default. Above the engagement TPS threshold it will go open loop, below the disengagement threshold it will go back to closed loop.
Fuel Trim Limits allow control over the short term and long term fuel trim ranges.
