ECM is a very "Narrow minded" program compared to WinOLS. WinOLS is a raw editing tool with no limitation on what you can see and change. There are no "Drivers" as Alientech calls them. You need to source your own DAMOS (.DAM .A2L) Files and match them with software and hardware versions.
To do this you need to purchase the Damos import plugin and Translation plugin. This will let you import damos files. It does not provide you with any. if you dont use Damos files you are working in the blind for the most part. You can train your eye to recoginze maps and the various bytes in general. but for doing things the proper way, Damos is pretty much needed. WinOLS Is by far superior in every way. Yet it does not come cheap.
Go with a genuine version and watch some youtube videos of people using it. read up a little in here on the finding maps/Definiton part of the forum. Lots of great info for newcomers of WinOLS.
