This was our original analysis of the HD closed loop ECM done in early 2007. While we have learned a great deal since then, much has changed, some of terminology was less than ideal and even a few of our conclusions were not quite correct, but our analysis of the heat and how richening the mixture can dramatically cool the engine was indeed correct.
