Chris Ehmke is joined by Nick Priegnitz, of Duramaxtuner, to discuss in detail the evolution of engine control modules and how tuning has progressed over the years!

Nick breaks down the history of GM's Duramax ECM platforms, walking through key model year ranges,from early LB7 and LLY trucks to LBZ, LMM, LML, and the latest L5P platforms, and explains how hardware changes, operating systems, emissions systems, and security updates shaped the tuning landscape.

They also discuss the major ECM milestones that changed the diesel performance industry, how emissions regulations impacted tuning development, differences in tuning strategy, and where ECM technology and diesel calibration are headed next

Professor Nick utilizes his almost 20 years of diesel tuning knowledge to give us an episode with immense amounts of knowledge. Enjoy!
