Dont get me wrong with the next bit I'm all for proper remap work but anything that increases the number of connections in the system or bodges the information going from one component to another is bad. Maybe it was ok back in the 90's when fuel injection was simple and the duration was the only factor the system could control but now with multi stage, pre and post injection not so much.
given the quality of the installation of yours its almost a miracle that it was running at all.
