Your absolutely correct. I hear that all the time. It does not work that well. I don't know many fast guys doing it that way. That is assuming it always runs quickest, in all weather, with any number of water grains, at the same air/fuel ratio. Not in the real world. The majority of the faster EFI cars use it as a reference, same as the carbureted guys do. We have different tune ups, or fuel pressure adjustments we make for different conditions, just like the carb guys changing jets. The guys telling the "It tunes it's self going down the track" simply don't know what most of us actually do. I have helped several guys pick up by putting their cars back into Open Loop so they don't try to make adjustements. It simply does not work that well in the real world.
