As Map 000 has one row, and therefore a 2D table, there is no row header and the next segment beginning at 0x19954 is the map data. In this case 0x2 * 0圆 = 0xC which is added to the address of the column headers to find the next segment of the definition. The column headers take up 2 bytes * number of columns. So adding 4 bytes to the address of the map gives the start address of the column headers: 0x19948. The column and row counts each take 2 bytes, or a total of 4 bytes. We know the start address of the map definition - 0x19944 offset from the start of the. The number of rows and columns are easy to obtain, but the other information requires a bit of simple math.

When creating a definition for Tuner Pro the key pieces of information are: So looking at the definition for map000/0x934 beginning at 0x19944 we can see that this 2D map has: | column count (2 bytes) | row count (2 bytes) | column headers (2 bytes * column count) | row headers (none if row count = 1, else row headers (2 bytes * row count) | map data ( 2 bytes * column count * row count) | The map definition has the following format: Once the index of map addresses has been located, and the method for locating the start point of each map definition is understood, we need to look at how the information in each definition is structured in order to extract useful information.
This is the start of the definition of “Map 000”. Putting this together we now know that the ECU reference to the first map is: 0x19010 + 0x934 = 0x19944. This should be 0x19010 for all NNN ECU’s. map file to the beginning of the fuel map. Because the Nanocom map format bundles both the variant and fuel map together it is necessary add the offset from the start of the. This address is an offset from the beginning of the fuel map. The map addresses are 2 bytes or 16 bits long, and the first map address should be 0x0934 in the EU3/15P maps at least. As an aside “0x” indicates the number is hexadecimal, and the hex editor might require you enter this prefix. Using the hex editors “go to position”, “go to offset”, or “move selection to”, enter the offset 0x1CEFE and hit return to get to first entry in the index list. The index of maps is located at an offset of 0x1CEFE from the start of the map file. The loaded file should look something like this: bin of the fuel map as it avoids a lot of the messing around with offsets… It’s actually easier to work with a straight. Once you have got your hex editor installed the first thing to do is open up your.

I haven’t really used Windows or Linux Hex Editors so can’t recommend anything specific - I’m sure there are decent tools out there. I’ve also used 0圎D and that is possibly even better for the task at hand. I primarily use OSX and have been using Hex Fiend as my primary editor.
Step 1: Finding the TablesĪs a starting point you will need a hex editor. At a minimum this means understanding where the tables are located and how they are structured. The creation process requires a good understanding of the ECU file format you are creating the definition for. Out of the box there are no definition files available for the TD5 ECU so we need to create a XDF file from scratch.

Tuner Pro is a powerful free (but not open) map editing program that runs under Windows.
