VMSpc

Now you can use your PC computer to monitor your engine - with the VMSpc. VMSpc is an intelligent data translator that links your serial port to the engine diagnostic connector on your rig. Together with the special software, it allows you to read performance and diagnostic information right on your laptop computer. You get complete diagnostics, trip information, and a great graphing system that lets you display up to five parameters at once. You can even store the engine data to a file and load it into a spreadsheet.

But wait! There's more! VMSpc let's you program audible alarms based on any engine parameter. For example, you can set it to play any WAV file (grab a microphone and record your own!) when your road speed reaches a certain point. Have it played once, once a minute, or continuously.

And you can create a "Tank Minder", which provides a miles-to-empty calculation based on your tank size and fuel economy. VMSpc lets you enter correction factors to compensate for a poorly calibrated engine. You can even program gauges to read in metric, if you desire.

Professional engineers use VMSpc to test their vehicle designs. Now you can use the same tools to test your coach.

Feel free to download the VMSpc software - it's free. In fact, SilverLeaf Electronics is committed to provide the VMSpc software and all updates absolutely free on our web site. We welcome your input, and encourage you to tell us what you'd like to see in future versions of VMSpc.

New! Wireless Versions for J1939

If you have a J1939-equipped engine, you may be able to connect with Bluetooth or Wifi. You can recognize a J1939 engine by the fact that it will use the black 9-pin connector, and the engine is 2004 or newer. (A few older engines also use J1939. Call for more information.)

The Bluetooth connection requires either a PC with built-in "Smart Ready" Bluetooth, or a "Bluetooth Smart Ready" Bluetooth adapter. Bluetooth has the advantage of being able to automatically reconnect each time you use it. The Wifi version requires a little more effort to reestablish the connection each time you use VMSpc. Both versions have plenty of range, no matter the size of your RV.
