This is what the table looks like in Tunerpro's 2D data viewer:

Into the hex editor and it looks like the data is in 8-byte columns:

 now switch to the 3D viewer:

You should download TunerPro RT and have a play with it, it is a very powerful piece of software.

I have had to do that too, in the past. Its much easier to spot patterns in the data using TunerPro's 2D data viewer and then switch to the hex editor to determine the lengths of the axis and then the 3D data viewer to examine the shape of the map.

Working from a disassembly you only get the start addresses of tables or data so I still use a hex editor to determine the lengths of the axis with the

are the MAPs and conversion lookup tables in the BIN or in external eeprom/flash ?

example , plotting a 3d table from 09B0 of 8 bytes x 11 rows looks like a nice looup for something..

LMAO..  well..

a hex+text editor, Look at the characters cross eyed, spot pattens, pull out data in groups of 8 , 10 , 12 or 16 bytes, paste into excel, do a hex2dec and then graph it

The tables and other data are all in the binary. I'm working on an IDAPro script that will automatically seek out the tables based on what I've discovered from analysing the X90 code. I haven't looked at this code yet, other than to note that the code start address is the same as the X90 which leads me to believe that it is probably the same code but with different mapping.

What software package did you use for that? I usually use TunerPro for sniffing out tables if I don't have a good disassembly.

I have now copied the binary image from the processor's memory, it is available here:

http://www.rhinopower.org/ECUs/71EE0/docs/EF21.bin

 At first glance it looks very similar to the binary for the 79E50 X-90 ECU. This is to be expected as it shares the same PCB.

This ECU uses the same circuit board as the X90 of similar vintage, the firmware is the only difference. The additional board on this one has been fitted to eliminate the immobiliser - the ECU came to me because the company that fitted it made a complete hash of the job leaving the vehicle immobilised.

  This ECU could be remapped using a daughterboard.
