Testimonials

We recently bought 2 Major Diesel software kits and adaptors to use in our training facility. We heard of Major Diesel several years ago when we were looking at purchasing a new scan tool. At that time, we did not have much history or experience with J-Ball so we resorted to buying a different scan tool. Since then we’ve had more and more students coming to our facility, telling us that all they use is Major Diesel software and that they are not familiar with our scan tool.

A major selling point to us was that it is capable or scanning DPF and SCRFilters up until now our training engine was not able to perform any type of regeneration on a truck We went on to order 2 units, when these units got delivered Major Diesel technical support was amazing in getting us installed and activated. Nexiq adaptor was faulty and we struggled with this for sometime, however with their amazing team at Major Diesel we were up and running in no time.
