Following on from the last video here is the common mistake seen in allot of calibrations, if you run a fuel pressure sensor then you should really populate this table. Here I show the end effects on fuel final and duty associated with relative fuel pressure changes, the reason this is important is on the action of any limiters or other items that by nature disable the fuelMltCll you then are relying sole on the accuracy of your look up tables, and if for example this is not set up and you have fuel pressure changes you can have large swings in delivered fuel, any time there is a gear cut request or transient throttle of certain magnitude to name but a few this will be in action and if you have any fuel pressure dips and closed loop lambda is off then this will cause your fueling to be incorrect if all set to 1.000
