With this .xdf, how do your maps/tables look (garbage/perfect) like ?
I don't think there is a "correct" .xdf for a certain model.
For instance, I use one (for 5AM) that works good for the S4RS .bins, as well as the SC1000 monoposto but
not the bip.
If you find one that displays, say, more than 20 of the maps and tables correctly, chances are, the immo and lambda are at the correct addresses too.
You'll have to try and find what fits.
To avoid "bricking" your ECU, experiment
only with the .bin you downloaded from it, for starters.
I think that, .xdfs for 5AMs are more likely to be correct, for their respective .bins, as more people were interested and involved in developing them.
A quick search for ".xdfs/maps repository" in the forum
