Quick question and confirmation on engine management system operation, fuel delivery in particular, and just in case there could be some exception(s), lets try to rule them out by considering just Ford vehicles, and vehicles using O2 sensors rather than AFR (ie, not the latest/newer technology). With that said, now the question....... when a vehicle is running in open loop, will the PCM ever make use of LTFT data stored in KAM or will it rely solely on preprogrammed data?
*Pretty sure it's all preprogrammed data, but curious to verify. TIA!
