VMSpc - Engine & Transmission Monitor

VMSpc Engine & Transmission Monitor (via PC) Product Page


The VMSpc is a engine/transmission monitor for a PC using a software/Hardware combo package. It provides information to the driver such as speed, tach, coolant temperature, and mpg. It also logs trips and engine diagnostic codes. It gets this information through a VMSpc JIB connected to the J1939 and/ or J1708/J1587 data bus.


The USB JIB uses a USB-B connection and can be converted down to micro-USB as needed (by new tablets.) Some adapters fail in this effort. Its best to Use a "phone cord" (micro to USB-A) then convert A-to-B away from the tablet (in fact, at the buried JIB.) A splitter or powered-hub is often used on tablets. Be sure to prompt for the latest device-driver update if PC connection fails.

The Bluetooth JIB uses single channel BT connectivity.

The WiFi JIB uses either ADHOC (hardware v1.x) or AP/ Infrastructure (hardware v2.x)
