Recently got a ATD fabia estate, looking into how to remap and wanna play about with a few maps see whats been done to the maps compared to a stock map, something to during lockdown as the pd100 is a bit slugish.

I'm not sure you're going to have much luck, everyone on these forums has paid to have their car remapped, there is no pirate mapping community here, specialist software is needed to extract a copy of the map from the ECU, more specialist software is needed to examine and edit that file.

The only member here who dived into that particular rabbit hole was Faboka and he quit mapping Fabias a while ago.
