We have a 2006 Allegro Bus Cummins 400HP. Does anyone know where the J1939 plug is located on the engine for a VMSpc Silverleaf engine monitor Jib. And what kind is it. How many pins and size.
Bill...Once you start running the VMSpc program, you'll never drive your coach again without it running. I run mine on a small notebook computer to the left of dash. I can see the big gauges and no exactly what my coach is doing at a glance.
I can watch my rolling mpg and actually make changes to my driving by seeing the mpg change. When I pull into get fuel, I check my fuel used and know within a couple of gallons how much I'll take.
