VMSpc Engine Monitoring for PC.

v4.0.5 Software Feedback

v4.0.5 was released in late June 2016. As it has significant issues, it's "Experimental only" for now. For First-Time USB installs, use v2.5 ~ v3.1. Leave comments for needed fixes here, first checking the bug-list to see if its already been added. Of course, please add needed detail on PC type, Operating system (XP, Win10...etc) databus (J1708 etc), USB vs WiFi...

Reset Mileage

After 70,115 miles I had to put in a new engine due to improper balance of Coolant by previous owner. I do not want to reset the coach data for total miles, fuel consumed, hours, etc. However I would like to reset those items on the VMSpc. Is this possible? Due to a few miles traveled, I will need to enter these numbers manually in the beginning. Thanks

4.0.6 interface ideas for you guys

Here are a few trial interfaces in version 4.0.6

Picture heirachy

There should be some kind of hierarchy for the pictures. One time I load and my guages are on top and the next time the picture is covering the guages. There should be the same for stacking pictures too. Also a default wallpaper size so I can create a background that has menu boards to place buttons on

Change plug?

I just traded in my older motorhome on a 2010 model. The old one used a 6 pin plug for my VMSpc and the newer one has an 8 pin. Can the plug be swapped out?

Freightliner dash guages going wild

Got my updated jib back For the 2017 Cummins 450 with the 500k green twist on plug and all the guages on the Vmspc are working ok. But my problem is every few minutes the dash warning lights go crazy. ABS, Check engine and other lights come on and off.

Monaco Windsor '99

So I've got my JIB and now I can't find the diagnositc port for the engine, I can find one for the ABS and the gearbox but not the engine.

Of course when I initially located the port I didn't get down far enough to see the markings that is was for the ABS only.

I've checked in the fuse box under the drivers window on the outside and I've checked in the engine bay.

Did the Cummins 330 not have a diagnostic port?

Unknown code

I have received a code that doesn't show up on my list and Cummins can't tell me what it is either. I have a 2012 Tiffin Allegro Bus with an ISL 450. The code is SPN 09951-31

Old Hardware, new laptop

Finally got around to replacing my old Thinkpad running MS Vista, with a new Lenovo windows 10 11" foldover PC. I have been using VMSpc for almost 10 years with my Holiday Rambler WBS35 Endeavor with a serial JIB and a 25 foot J1708 I made myself.
I was using VMSpc ver 3.01 because it always worked and did exactly what I wanted. I had downloaded ver 4.04 and tested it but it was not my running version.

So long story short, downloaded the latest dist. disk, drivers and spent 2 days trying to make it work on my new WIN10 PC w/o success.
Finally called Art and after reviewing all my setup troubleshooting he suggested I replace my 9 year old serial-usb prolific adapter which would not run with the latest driver ( code 10in device mgr).
Quick trip to Best Buy, bought a new adapter and 5 minutes after installing I was up and running.
Thanks Art! Also Kudos to all the Silverleaf team, great products and great service.

Changing the font sizes

I am using a fairly small tablet and found i like the full screen mode. I am making the numbers large enough to read but that make the text way to large for the space. Is there a way to use smaller fonts for the text in the gauges?

RCA Cambio W1013DK Power Supply Cord

I prefer to power my RCA 10" Cambio W1013DK with a DC power cord. I did find some on eBay listed for this purpose. Does anyone have experience with this? Are there any problems?
Thank You!!

logged codes prior to VMSps install

can the VMSpc retrieve logged codes that happened prior to install

Time clock

Is there a way to use the 24 clock?

50cycle and Silverleaf

What do you do when you want to plug your coach into shore power--but, say, you've landed your American-made coach in the UK?

How does this 50cycle and 230VAC pan out on North American-style 220VAC 60cycle?

The coach in question has this symptom: When plugged into shore power, the the transfer switch won't "pull in" (latch) and the error "Bad Frequency" is displayed on the Total Coach panel.

I've emailed this question out specifically to folks who have indicated they're in the UK. Yes--All Six Of Them! ;-)

You folks and anyone else with specific knowledge are welcome to join us to reveal your clever solutions. And, if things were sometimes by trial and, er...retrial--share those too!



Polling for PID's?

After a few months of Hiatus im back to working on my Bus.. Ive been running the VMSpc on an Asus tablet which works very well..

there are several PID's which dont show up in the VMSpc yet do when I use the International Navistar software and interface...

for example PID 164 is my High Pressure oil pump.. that is what controls injection.. its the first thing that will go wonky when its sender starts to go bad (and they do often)..

the Navistar software appears to Poll the J1708 interface and request that PID.. I see where the J1587 protocol spec supports requesting a specific PID.. as not all of them are sent all the time.

is there a way we can get the VMSpc to poll the interface and request a PID? it looks pretty straightforward to do it...

I had shot out a couple emails with some detailed data on this but got no respomnse so I mayu have sent them the wrong place..


driver update for windows 10

Any word on the windows driver update for Window's 10 tablets?
How will we know when drive will be available ?

Odometer not recording miles, time, fuel mileage for trips.

V4.0.6 newly installed on W7 PC. Upgraded from a v3.?? And XP.

No recording/reporting of miles, time or mileage on odometer gauge. I believe the last thing I changed was my engine file; went to Cummins ISC 380HP from whatever was a default. I think, based on .txt log file, that it was working.

Any ideas of what's wrong??

I just deleted the odometer and tank minder, saved the layout and reinstalled the tank midge and odometer. Not sure if it's working yet but "time" doesn't seem to change (increment) with app running but engine off. I thought my old version did that.

opening port

just upgraded to surface pro 4, everything worked fine on old tablet pc I an now getting no comm. what port do i open for communication >?
i do have the correct engine etc

change from a 7 pin to a 9 pin

when I changed from a 7 pin connector from my cummins 315 isc to a 9 pin connector for my 350 isl I was told I had to cut a lead inside my JS501 box. can anyone tell me what lead I'm a supposed to cut to make the new connector work properly thanks bob

New Green 500K connector and Setup

Received the new 9 pin twist lock plug and had a problem installing it - got check engine warning and trans comm fail - no J1939 Data. Called and talked to Mark and he requested I send the unit back to SilverLeaf for an update. My question is - when I get it back, what version of VMSpc will best work with the new setup? Currently using 2.5 but that was with my old coach with a CAT 350 made in 2007. This new 2017 Newmar Dutch Star has given me some surprises with SilverLeaf. One other thing, I use Pressure Pro Bridge in the setup.

Thanks in advance,

Latest ideas for v4.0.6

Here's the latest idea for the new build; what do you think?

21. Alarms
1. Single-button "Alert" (audible alarm) feature in gauge properties. GUI "Sound Effects" pop-up then selects file or _records_from_local_mic_. Is there a way to show time-length of selected file? How long is Ride of the Valkyries anyway?

Normally, one hits (Advanced), (Audible Alarms) to get a 'Sound Effects' box. Select your gauge, Give it a value (like, over 15 etc) then pick a file and (OK). Mostly overlooked yet easy enough to accomplish.

Not a big deal--but why bury it in advanced features? Its a normal expectation to have an Alert any more. Alerts for texts, alerts for email, alerts for tweets, low battery, charged, dropped signal...

This will accomplish two simplifying goals, really:
1. Group & Reduce clicks: Gauge (Properties), (Alert) _and_
2. Add Record-Your-Own -in the event you (or the sweetie) have a really great radio voice!

Your thoughts?


Various Gauges Momentarily go to Zero

For quite some time (well over a year) I have had this problem that various gauges will go to zero for 10-15 seconds then return to normal. I have not been able to determine a pattern or commonality with the occurrence. But, in the course of an hour I will see it several times in several different gauges! I first noted it in our previous RV, but when we changed RV's summer of last year the problem followed us to the newer one. Both had Cummins engines, the previous one was a 2009, current one is a 2013 model!
In the last several months for unrelated reasons I got a new laptop for the job and I installed newer VMS programs v3. Nothing has made a difference.
Anybody else having a similar problem? If so any suggestions on how to fix!

Can't locate my engine

I'm converting a school bus into a motorhome. It's an 1999 International AmTran diesel. It has the diagnostic port under the dash to connect the VMSpc hardware to. I looked at the VMSpc user manual and the additional engine codes but could not find my International DT466E engine listed. What other engine is my engine similar to that I can choose so that VMSpc will interpret the codes correctly? Thanks.

Feature request

I would like to select LOCK SCREEN once and have it apply through reboots.

VMSpc Ver. 4.04

I just received my VMSpc JIB and the software Ver. 4.04 was included on a CD. I read the ReadMe.txt file about the drivers not installing on older Windows XP computers, and other than saying they had to be installed manually, how do I do that?

Cost per mile enhancement request

It occurs to me that it would be neat if there was a way to enter # gallons and cost/gallon when resetting the tank minder. With that info, I'd think it would be fairly simple to add a cost per mile entry in the Odometers. I know yall are buried with the 4.xx releases but perhaps when things calm down???

Check engine light blinked a few times twice but nothing reported and nothing in the diagnostic file

Cat 3126E Allison 6 speed in a 2003 Fleetwood Discovery. Yesterday, while rolling hills in NY, my check engine light came on and went into a 10 second blink for 30 seconds. Did this twice. All readings on my monitor were good. Checked the diagnostics file and there was nothing in it.

I'm new to VMSpc and diesels for that matter. Is there a reason that the light would come on and VMSpc not capture a code? Is there a way to use VMSpc to get the code from the ECU? Is there another way to get a code from the ECU?


Signals from ECU

Does anyone know if there is a method of getting VMSpc to show a list of the actual signals being received from the ECU?

Remote monitor vs. Mini notebook

I'm reinstalling my VMSpec after several years of a hiatus and am totally not up to speed with the latest developments / options. A couple of questions.

My label says
JR501 J1708/J1939 Interface
hw 1.00 sw 1.05

Do I need to reference anything special when posting to the forum ? Is "JIB" version significant ?

Next, where's the best spot on the forum to view users set ups to see how best to install with the latest mini lap tops and remote monitors. I have this fantastic spot in my dash (shown) that I deliberately left for installing a remote screen. What screens are recommended for this in dash set up and are they touch or regular ? I'd like to stow a dedicated mini lap top out of site if others have set it up this way.

The 2nd option would be a folding / convertible tablet or mini computer that I mount to the left of the dash on a stand I can fashion but the issue (a few years back) with this idea was that no lap top let the screen lay all the way flat and parallel with the keyboard. Lenovo makes a 10" model called Flex that now solves this problem so I'm deliberating between the remote, in dash, screen and the Flex. Suggestions or pitfalls with the remote screen from users or admins welcomed and wanted. I guess I'm leaning toward the Flex and may have answered my own question but I've not been following the forum and am not sure what other options have come out lately. Thank you.

PC port failure

I am running VMSpc 4.0.4 on a HP Pavilion with Windows 8.1.

I have found a few threads discussing this problem, but none of the suggestions help. My device manager shows that I have only one port, COM1, but the Communications dialog seems to think there should be a COM3 and tries to use it. I have tried to update the driver via the device manager, but it indicates that the driver is up to date.

Has anyone else had this problem? Do I need to get an update from Silverleaf?
