Hi, I've been requested to pull out some A box info.  I downloaded the A rom and ran it through my analysis executables.

As usual this is machine generated, and should be examined before being relied upon.

NB maps / tables sometimes have axis data points immeadiately before the map data.  In these cases my offset will start with the axis data.  I've started to work on this problem and if any data exists in the 'offset due to axis' column then I have worked though it and given the start of data in the column named "first data byte".

CSV file attached at the bottom.

Nice one Spen

The locations will be correct.

The easiest way I have found is to edit the M box XDF and replace with your new address.

Rick

Yes, you have to spend a lot of time with both hex's open to compare and search for axis and such. Normally once you are in the correct region you can spot matching byte sequences and piece things together.

Alright, so I started and tell me if I am crazy.

Attached is a C program that parses an XDF file for Tables and Constants. We really do not need the constants, so I am skipping all the reading of that data. From the table data that the XDF contains, I will have altered all the "Address" numbers (somehow) to replace them with what spen has on his CSV. The dirty work is going to be finding the "axis data" from the existing addresses, as I described above.

So, I read the X and Y axes information from each table and I store it. Then, I will make a pass within the bin file for which the axes data is listed in the XDF and read those segments of data in the memory. Whatever the Xaxis and Yaxis variables are I will read according to how they are sized based on the information within the XDF.

The hard part comes next. I will have to do a pattern match for each of those axes segments within the bin for for which I want to build the XDF. IN our case it is the Abox. If there is a match, I call it good and write that address in the XAddress and YAddress segment of the XDF file.

The only assumption here is that the axes "data" in the bin file are the same across the two different bin files...

Any ideas?

OK, cool. I will code up the rest of it tonight and run it.

can spen (or somebody else) tell me how they got the original MAP addresses? nyet's email just bounces back.

Corresponded with nyet all day today. He told me that he did exactly what I am doing for the Abox. He did all the hard work, as his Mbox .xdf adn .bin are what I am using. I offered big thanks. He also said that I should not bother... just get a Hitachi MAF sensor, recode the cluster and engine codes, and simply flash the Mbox file in there. Solid advice. I still will go after the Abox to prove myself that it can be done. You will all enjoy the benefits.

Can you share details of the algorithm? We do not necessarily need the code itself, but the principle of the operation. A few sentences like I did above will help.

I do not know what to do about assessing the quality of my work... or finding errors. Any information you can share is greatly appreciated.

I trust Nye's work the best. He has a consistent XDF file and the standard BIN file from the Mbox (I verified that). Even there we have a problem. Tony#NM said that there are differences between some Mbox files... We do not know why Audi did this and not give it a different name. Nye said that he started from an Allroad Rbox, an A6 Gbox and an RS4 Rbox. He did not specify whether he had XDF-type data for either of the three. It worked for him. So my beacon now is his XDF and bin file.

Also, for finding maps, I followed a link to a tune reverse engineering site from the TunerPro.net Resources page. Those people are mostly dealing with Porsche and BMW maps, but they explain the principles of the reverse engineering pretty well. In that spirit, I authored a little C routine last night to drop the contents of any bin file to an HTML table, complete with addresses in dec and hex and the printable set of the unsigned char data. I am attaching it below an will post a separate thread about it.
