Recently purchased a 2010 Allegro Bus with the new DEF engine. The only engine file I find in the software is the one for 425 HP Cummins ISL. Also When I use the PID sniffer I ONLY have about a dozen PIDs showing, I think there should be many more what is happening or what am I doing wrong? This is my fourth coach using VMSpc, pretty sure it is not a hardware problem. The only other difference, it is on a Tiffin powerglide chassis with the Aticia electrical system.
