I love your desire to understand everything,but sometimes we must also surrender.I personally do not know what it expresses that area.The 2d graphics in full expresses all the functionality of the ECU,(tabbele,errors,controls, etc, etc...)it Would be nice to be able to explain each address on the map, however, do not believe that sie can,as this information relates only to the manufacturer and as a rule can not get out.We have to thank the forum like this where we can share information and to plan, plan to go next.
