I have been fighting with knowing which XML files work with which version of ECUFlash (namely the 'endian' issue). For lack of a better suggestion to date, I've been adding an 'xmlversion' tag in XMLs that I have 'updated' for use with ECUFlash V1.3 and on. For example, the top of my 'fixed' XMLs now look like this:
<rom>
___<xmlversion>1.3</xmlversion>
___<romid>
______<xmlid>(xmlid value)</xmlid>
etc., as before.
Feel free to adopt this scheme if you wish (including Colby perhaps, for a later ECUFlash release). It very least it attempts to document a standard method of tracking XML versions.
