I installed VMSpc today on a Cummins ISL 400 2007 Tiffin Allegro Bus. The following gauges did not provide any information(read 0): oil temp, transmission temp, fuel temp, transmission (gears), horsepower and torque. I am not sure if that information should be available from the Cummins and Allison electronic controls. If it is, how/where should I begin to look for the problem?
