Most, if not all of the information you will need is already on this Forum. Read the threads in the Tuning For Economy and CAX Files subcategories of the Petrol / Gas section.

Here is a link to a thread that discusses how the final LC (Lean Cruise) EQ values are calculated.

You will need a LC CAX file to activate LC in your calibration.
