VMSpc Engine Monitoring for PC.

Color of Text

I have been using V 4.03 on an old XP machine for several years. I just downloaded V 4.0.6b to a Windows 10 tablet. The text inside the gauges is a light brown color and the values are in white. On my older screen they were both black and much easier to read. The manual has only a sentence or two about changing text color that is not of much use to me.


How can I get odometer data with V4.06

I reported in the 4.06 feedback topic that I do not get odometer readings with 4.06. I would like a suggestion.

Running VMSpc with USB JIB. Windows 10. CAT C-10 engine in a 2000 Country Coach.

Tried all the data bus settings. No luck.

Any help out there?

Certain Guage Data stopped displaying

I have been running vmspc 4.05 for a few months now and recently my transmission gear info gauge stopped displaying what gear i am in. Its just ?? for the last couple of weeks. Yesterday the Oil Pressure stopped updating. I have made sure my malwarebytes & defender scanner has your vmspc folder excluded. All the other gauges appear to be working. Although the mph and water temp changes lag quite a bit more than they did a month ago.

Is there something I can do to fix this? -Bill

Adding Guages

Greetings... I tested v4, but it looks like v3 is still the way to go for me for now (still not getting the gear selected in the transmission gauge for starters). Before firing v3 back up, I ran the PID sniffer in v4 and grabbed some screen shots because of my OCDness. Anyway, I noticed that the PID sniffer in v4 gave me a 412 PID for EGR, which does not come up in v3's PID sniffer. Would I be able to get a working EGR gauge in v3 if I copied all the parameters from the EGR gauge in v4? Thanks in advance.

Files fail to load - no trip odometer information

When starting Silverleaf 4.06, messages telling me that a couple of files failed to load display briefly (too briefly to copy down). Could that be why the trip odometer displays zero for miles, mpg, and hours? The simple odometer and fuel meter are displaying correctly, as are rolling and instantaneous mpg. (J1708 6-pin, cummins ISC 350). Computer is an Alpha Switch running Win 10.

Won't Run in MAC/Parallels


INSTALLED v4.0.5 in our Windows 8.1 1 running in Parallels 10 Version 10.3.0 (29227) in MAC OS Sierra Version 10.12.4, configured & tested OK. Now, when we try to open it, all we get is “Error Reading File”. Sure wish there was a Mac version of the software.

Wallpapers for backgrounds

Here are a few wallpapers I played with when setting up my system
Convert the .jpg to a bmp and use them as wallpaper backgrounds
Sorry I couldn't upload them as .bmp

SeeLevel tank monitors

I have SeeLevel tank monitors.
Can they be integrated into the VMSpc system?

v4.0.7 Software Feedback

With new software comes new opportunities and...maybe some bugs.

Lets hear about your experiences and how this software is working out.

--If you would, also let us know which Windows version you're on and which, prior, version of VMSpc you used.



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

v4.0.5 Software Bug-list

FIXES (needed):
1. Win-10, Defender gives us the boot On install, if program 'sits' idle without being installed, Defender boots it out. Install program is not the problem, Defenders' 'Heuristics' are flagging us as a maybe. (In Work; current work-around is to disconnect from the internet and disable Defender, then re-enable after installation.)

2. Help menu item, needs a link to FAQ and Website. Link to manual works. Working on a 'boiler plate' which will consistently work on OS XP ~ Win-10)

3. Win10, WiFi Dropouts after ~45 min. Mouse-trick didn't work. Other method to prevent interruption? (Root-cause is Microsofts' aggressive update method; no Silverleaf-side workaround found. Problem is expected to change with MS "Creators update"--how? TBD...)

4. Odometer "day one" odometer isn't really day one but is today, instead.

5. Gauge Flicker J1708 & Serial JIB, 'red' values periodically, ~1/10th sec --Otherwise okay. See #7

7. Max Gauges: J1708 based data frequently spike. Any little spike (as displayed) also hits the Max with artificially high values. Parsing or Rule situation? (Still hunting for cause)

8. Color Palate (XP): Palates won't work...

9. Full Screen (XP): Wonky space at screen bottom.
(Moved down the list. Very difficult to fix; focusing on the more problematic issues instead.)

11. Engine Type: Wrong directory opens by default, reverts to My Documents. Next build: drop Additional Engine folder in c:\VMSpc and the balance of stuff in the hierarchical folder (...\VMSpc_4.0.6). This puts the engines in a constant-known location.

12. When playing .WAV file: Hangs on some Win-10.
(worked on this but couldn't reproduce it.)

14. Full Screen: Under Win-10, Tablets: Long background press does not ESC from Full screen.

15. Trans info: Gear Attained missing on (new) J1939 chassis.

16. Tank Minder Under Win10 Tablet (without keyboard), cannot select custom color.

17. Tire Status; Learning Mode This times-out in 20~40 seconds

18. Tire Status; Presets & positions Tires Populate wrong. Populates with '0' rather than preset. After preset is selected, reverts to '0's again; filling screen with tires.

19. Tankminder Wrong MPG, when doing a Partial-Fill, wrong MPG is calculated. (Need more data, inconsistent amongst users.)

20. Maintenance List; displays "0" (mileage) interval (on the list) though it functions correctly while doing so--and while editing. should read 5000 or 10000 or whatever the interval is both during Edit and on the List.

21. Data Logging; Should--but doesn't continue logging when program is closed and re-opened. "In versions 3.xx the selected data remained selected and was always there without having to always re-select after ever closing of the program."

22. Anti-Virus and Install; Some AV screw up the process; Its been found that, during install, When certain AV is active, it may filter out files at random. This may be a process of scanning them real-time and them getting...'lost'(?). Can we build in a check-sum; verify that the needed files are present and fixed if not? [SX include wonky Odometer, fuel & mileage calcs and missing gear-attained indicator.]

23. J1708/J1939 tool; after being set, it may revert back to 'Both' or 'leak(?)' data. After selecting J1939 only, program reverted to 'Both' on its own randomly.

24. Engine Corrections Prefills Offset and multiplier box with spurious data. Can be zero'd (by entering 0.0 or a needed amount)--but will revert to something spurious when opened again unless unique value is inserted.

25. Gauges Not Staying Locked Gauges stay Locked while program is running. Once program is exited and restarted, the Gauges are No Longer locked.

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
