A greeting to all,
I write this my first topic to ask you for a hand to try to understand the values that are found in the maps, as written in my other post to this link st? handling the ecu of the engines, land rover td5, both defender and discovery, for? I have almost no knowledge of how you run maps, or rather I have read several documents regarding the mappings, but in this unit I can handle.
I would try starting with the order, posting some maps, the map data are "right" in the sense that the indices of the row and column, as well as? the size of the table, are at the head of the block of data contained in the memory, the addresses of the heads of the blocks are located in a table contained in the same file to the address 0x1CEFE (referring to the entire file of 256k content in the flash of the ecu) the addresses in this table will vary from one firmware version to another (defender, discovery, as well as? several years of production)? you keep positionally equal, the cio? having 2 of these tables from 2 stations in different versions, taking the first address and the first address of the other, which are usually different between them, if you go to the corresponding addresses are 2 tables that are identical in both size and the indexes for the values, then do the same thing.
My "problem" ? understand what these tables, and most of all, what indicate the indexes, below I'm attaching some pictures of these tables maps that I assume have been deciphered, but I have not very clear the meaning of the axes.
this table manages the egr, and I know that by putting all the values to 16000 disables the functionality? (but I don't know what are the values on the axes) Egr.jpg
these two tables if you vary the behavior of the engine, respectively, with the gearbox in a range of fast (Hi) or low (Low), the control unit knows the gear reducer through a contact on the gearbox itself, I have seen that variandole you vary the performance, but I don't know what to do, they would seem to limit values to which the engine is coming, a kind of limiter. there are 2 pictures of the Hi why? in only 1 I couldn't put all of the values in the table. reference hi cut parte2.jpg reference cut hi.jpg reference cut low.jpg
