Summary of the information posted above, thanks to the contributors who gave me the info to compile it. All info below was garnered from previous posters in this thread

Definition Files Damos and ASP2

Damos, (.dam) ASAP2 (.a2l) are database and description files giving addresses and names of maps. These are collectively known as definition files. Definition files can be added into WinOLS using the damos import option. Other tuning platforms may also allow their use. It has been pointed out that .dam is now obsolete format, these have been replaced over last 15 years or so with .a2l format files. They achieve the same thing but in a more standard format.

Definition files are most commonly in German (Depending on who compiled it) and gives information on start and end address of specific maps. Axis definitions, Factors and Offsets.

Maps are normally associated with a specific location in the bin file. Many ECUs have several software versions over their lifespan and the maps are stored in different locations with each version, Different software versions of the same car can move those maps to different locations, so therefore definition files are not universal- although you might get lucky and have a similar DEF, When selecting a definition file software numbers are important as the addresses and some maps will change as noted above.

Definition files are specific to a particular ECU binary file but occasionally they can be used with other files that have the same map alignment and constants, but this is rare. They are still a very useful tool to create your own map structures based upon similar appearances when viewed graphically, as the structure of data between a great many ECUs is the same, just in different addresses within the file. Once you have a good understanding about the 'look' of common maps it becomes easier.

Once you have a good understanding about the 'look' of common maps it becomes easier, but it has been pointed out that even then it might be complicated to modify the maps to successfully make the changes work unless you can correctly modify the correction maps. Mainly limitation maps.

Damos files are available for purchase from suppliers, Google will lead you to many tuning forums that have access to these. They have also reported to have been for sale on Ebay.

great structured info. Thanks a lot

I really want that file thanks...

[quote="panos1975"]i agree that without damos you are blind but if you have damos ande you don't know how to tune each map and how each map works.....you are in dead end.so first of all understand 100% how an internal combustion engine(and all of engine's peripherials) works and what each map doing and how it works....this the 100% of
i agree with you.
