When Mack Trucks first got serious about bringing electronics on their trucks in the late 1990s, they dubbed the electrical system on their engine V-MAC III. This essentially covers all Mack engines produced from 1998 to around 2004, give or take a year or two. It was with the EPA mandated 2004 emissions that they started to move away from V-MAC III. Mack now calls these trucks "Mack Legacy" vehicles.
About the V-MACIII Software
If you are looking for software that covers both Mack Legacy vehicles and today's trucks, you can purchase the Premium Tech Tool software for Mack, Volvo, or both. However, if you prefer a separate, more simple program for only the Mack Legacy vehicles, Mack has made this V-MAC III software 100% free. All you need to do is add this product to your cart, check-out and a download link will be emailed to you. This package includes the V-MAC III software, reprogramming software, and help file.
