7. V-MAC III Software

As of today, you can purchase the Premium Tech Tool software for Mack, Volvo, or Both. While this software is compatible with both today's trucks, it also compatible all the way back to the Mack Legacy vehicles. This includes VMAC I, II, and III. However, if you have ever used the Premium Tech Tool software, you know how much of a nightmare it is. 

This one software program is designed to work with all Volvo equipment, engines, and trucks across the entire globe. Anytime you try to stuff that much into one package, you end up with the situation that Premium Tech Tool has. The program is large, complex, and very deep. It takes several hours to install on a good day, and it needs huge laptop resources to run properly. Through the years, they’ve had numerous issues and bugs to work out with the Mack Legacy vehicles.

Because of this, Mack has now decided to make the original V-MAC III software 100% free. This package does include the V-MAC III software, reprogramming software, and help file.

10. Connection Diagnostics Guide

The training team at Diesel Laptops has created an intelligent, step-by-step instructional document on diagnosing an Electronic Service Tool connection issue. The technology used at Diesel Laptops is intuitive and takes care of your diagnostic needs. However, our products only work if they connect. For that reason, we’ve created this report in the unlikely event your product gives you issues with connection.

There may be various reasons you have encountered connection issues with your device. This document, while not the absolute guide, is an excellent starter guide that could potentially save you valuable hours trying to figure it all out on your own. Diesel Laptops cares about you, the technician, and we take pride in offering this guide to you for free.

In this downloadable PDF, you will find detailed visuals, step-by-step instructions, screenshots, and issue related sections.
