The New version [To be renamed v4.1] is ON HOLD pending a patch. Seems we broke the Odometer. oops. ...And the Tank Minder. Version 4.0.8, J1708 bugs and all, is still available below (for now).

## Beta Testers may download v4.1 (for Win7~10) from here: --With the understanding that the Odometer Gauge and Tank Minder gauges are in-work (broken.) Do not give feedback on those. Not available (as a Beta) for WinXP.##

Even if you don't have the VMSpc Cables and Hardware you can still install and try out the software. You can see for yourself how easy it is to customize VMSpc to your tastes. And when you are ready to "go live", give us a call at (888) 741-0259 and we'll set you up with everything else you need.

Software upgrades are always free and no log-in is required. When in doubt: Read the manual.


Diagnostic ports vary greatly across the spread of coach-builds and years. Find yours and have a good look at it before you call. Refer to the Connector Document to identify what the Diagnostic sockets look like. Its regretful that, for this reason alone, we're not able to have an online store.

To start a fresh installation, download the latest "Distribution Disk," below. However, when first prompted, Open it (don't download it) --save/copy the Folder it contains to a place on your PC you can find easily, such as c:\ or your Desktop.

Install the drivers by Opening 'Install_Drivers.exe' Once the driver Software has completed, Install program from that same folder (ex: "Distribution_Disk_v4.0.x"). Reboot, open the VMSpc program with that new desktop shortcut, select your specific engine (when prompted). The first time opening you'll need to confirm that communications are set; USB JIB etc. Follow the manual on this--not too difficult. Need a hand? Call and we can walk you through.

If you are having difficulty Installing VMSpc v4.x, please refer to our All Versions Frequently Asked Questions Page for further information.

Be sure to give a call if you get stuck or need clarification.
