VMSpc Engine Monitoring for PC.

Cable Length

Well I just discovered this product VMSpc and I am excited. I am going to get my JIB/cable ordered this week, and I have looked at the software interface (way cool and intuitive). I am amazed at the slick union from the PID info to a Windows interface. This allows me to stick my tounge out a Freightliner (their laughable little driver interface box that I can't see when driving). Kudos to you guys the developers. Enough schmoozing. My question is cable length(s). I have built my PC (with open COM1 port) that I use for GPS, maps, etc. into the overhead compartments. Serial data interface should have no problem with this. But how long is, and what connector types, does the JIB have? I can find no pics of it. Can it be extended? To run a hidden cable, I'd estimate that I need about 10' from the diag. socket to the PC. Will a serial M-F DB-9 extension cable be OK? Or can the diag. plug side be extended?
As an aside, since I have not ordered the JIB yet, I assume my diag. socket is the "9-pin" variety? (This is a FL XC chassis, mfg. date 11/04, Cat C-7, on an 05 Itasca MH). It has 9 holes, but not all have a contact in them. It is 8 pins in a circle surronding a center pin with a keyed slot, but one of the 8 is smaller and offset toward the center.
Appreciate any input.

What a disappointment!

I received the package from Silverleaf on Friday evening and decided to set aside Saturday to install the software and hardware. I hoped I would be able to complete the installation in just one day, especially given the USB to serial adapter required. Well, I plugged the thing in, installed the software, started the engine on the motorhome, and the darn thing worked. Almost that fast. Now it's 9am. What do I do with the rest of the day?

Delivery was fast, customer service was friendly, installation was fast and easy.

Data Logging

Is there any way to log engine data with different sampling rates? I would like to log quickly changing data at a higher sample rate than some more slowly changing data. EG I would like to log turbo boost at a much higher rate than coolant and intake manifold temps. Is this possible? I really haven't looked at file sizes. Is the compression such that it doesn't matter?

Can't get the serial to usb adapter to work

I've spent a small fortune on serial to USB adapters trying to get the VMS program to recognize the link between computer and engine. I've owned the program since last February 2006, purchased it at the FMCA rally in Pomona, CA. We full time and since that time I've actually been able to make it hookup about 6 times and I've tried 4 different serial to USB adapters. I'm very frustrated, and know that the product is a very good one, but in this day and age why are we still trying to provide a product that still uses the serial port instead of the USB port that is, probably, the industry standard for laptops anymore?
I'm very disappointed in my purchase. Has anyone else had the same problem?
The unit itself glows white and blinks red when engine runs but I get the error signal,"Failure Between JIB and PC" or when trying other com ports "PC Port Failure". I've tried every port available and like I said on about six occasions it worked, next time I start the engine, nothing.
I've tried Version 2.2 with same results. I'm running XP home addition with service pac 2.

Changing Engines

I've been using VMSpc for 3 years now with a Cummins ISL, and I've recently changed to an older Blue Bird Wanderlodge with a DD 8V92 DDECII 475. I have questions about changing engines.

First, in the software, will just changing engines make those items that work be recognized, or do I need to uninstall/reinstall?

Second, while I have yet to find the dash diagnostic connector, I'm sure it is there. Most likely a dual-row rectangular connector. How do I get a new cable, or can you provide the necessary info to splice the cable I have into the system?

Third, which engine do I choose? You have two 8V92 engine listings, 450 and 500HP, but those do not necessarily relate to DDEC numbers. Blue Bird for example in my year used the engine in 450 (California) and 475 HP versions and the next year in 450 and 500HP, but both years were DDEC II. Earlier DDEC I were typically 450.

Transferring over to new laptop?

Hello folks

I am trying to get my gages back as I had them set up on the old computer. I did a full software download from website to the new computer. Then copied the VMSedit.exe, VMSpc.exe and the *.SCR file for my gages from old to new laptop. The .scr file is my personal configuration of my gages. My gages did not come out exactly correct on the new computer. Maybe 80%, but a lot of work to rebuild the remaining 20% (remember the 80/20 rule?). The old VMSedit.exe file did not transfer over in the same configuration, as it was set up on old laptop. The VMSpcedit file looks like the original, no matter what I do. I think this (the VMSedit file) is key to my problem. My old laptop uses XP Home, and new laptop uses the XP MCE operating systems. Anyone know of an easy way to get my old ages back intact on the neww computer. Thanks for any help here.

VMSpc J1708 Interface Board Problem

I'm having a problem with hooking up the VMSpc J1708 Interface Board (JIB) to an HP Pavilion zt1145. The JIB of course, captures and sends engine and transmission data from the diagnostic port on the MH to a laptop which displays the data. The port that connects the JIB to the laptop is a serial port. Since most laptops no longer have serial ports, a USB-to-serial adaptor (USB adaptor) is required to make the connection. I have been told by several people that not all USB adaptors are the same -- some adaptors may work on a particular laptop and others may not. We tried three adaptors and none of them worked on the HP laptop. Using another laptop, with a serial port, we installed the software and the JIB passed the data to the laptop as it should have. Therefore, we believe that the JIB and associated hardware and software is functioning properly. The HP Pavilion zt1145 has three USB ports which all seem to function properly with other USB devices. Using two different USB adaptors and two of the HP USB ports, Comm Ports 10, 11 and 12 were assigned by the HP when the USB adaptors were installed. The appropriate Comm Port was set in the VMSpc software and when the JIB was hooked up to the HP laptop, the green power light on the JIB was on and the red data light was blinking rapidly, indicating the data was being passed. However, no data was appearing on the HP laptop screen. Clicking the Advanced Tab on the VMSpc program and then Communication yielded a window that announced "PC Port Failure". This was the case for each USB adaptor and USB port used. Setting the Comm Port in the VMSpc program to Comm 3, with only the USB adaptor connected to the HP laptop, gave an error that indicated that the JIB was not connected -- this indicates that the adaptor seems to be working and that the problem seems to be when the data is sent to the assigned Comm Port. The speculation is that something (Windows Xp utility program?) is grabbing the data being sent to the assigned Comm Port before it gets to the VMSpc program.
So, basically I can't get it to transmit the data to that laptop. Any thoughts or suggestions?

Torque and HP on MB 926 engine

I recently purchased a MH with the MB 926 engine. I did download the eng. file and loaded it. My question is it appears that the RPMs need to be 1300 and over for the torque and horseower to display. I see on the 926 engine specs that at 1000 RPM the engine is producing about 680 FTLBS of torque and 133 horsepower. The torque rises on a fairly straight line to 1300 RPMs. Torque is flat at 1300 to 1600 RPMS. (1,000 FTLBS) and then pretty much a straight slope to 650 FTLBS at 2500 RPMS. Horsepower at 1000 RPMs is 133. The rise is a straight line between the following: At 1100 RPMs 180 HP, At 1300 RPMs 240 HP, At 1600 RPMs 300 HP, At 2200 RPMs 330 HP and at 2500 RPMs about 308 HP. Can this engine file be changed to follow the engine specs?

OBDII Plug adapter fo VMSpc

Is an adapter available so that I can use the VMSpc in my Chevy Truck? In my truck I find a rectangular OBDII plug; but the plug I use in my motorhome of course is round. Maybe I'm Google searching for the wrong thing. Can someone tell me how to mate the two together?



Does anyone know if I can use a system that I had on a 2001 Bounder Cummings engine on a 2002 GMC V8 Diesel?

Odd Cummins M11 diagnostic connector?

I located the diagnostic connector under the dash on my 95 Foretravel U320C SE (94 M11 Celect w/jake/HD4060). If it is the one I found, its a 6 pin diagnostic connector, rectangular (single connector layer, inline contacts).
My Foretravel wiring diagram shows a rectangle with the following pin assignments left to right:

B- ATA data link minus (J1587)
A- ATA data link pos (J1587)
F & D - no connection
E - ground (Bat -)
C - ign (Bat +)

B&A also connects to the ATEC TCU for the Allison HD4060, but from what I've read here the VMSpec software won't read data from this line.

1. Do you have a data cable with this type of connector? Have I located the wrong diagnostic port?
2. Am I correct in assuming that this older HD4060 won't communicate to VMSpec?

I plan on ordering within a few weeks... I can provide a digital picture if desired.

VMSPC and Tire Safeguard

Is there any current information for interfacing Tire Safeguard and VMSPC? I use both but it would be very handy to have the tire display show up on the VMSPC menu.

1994 M11 Celect

I recently traded up to a 95 Foretravel with a '94 M11 Celect engine. 370hp, waiting on the paperwork showing the uprate to 400hp by Foretravel.
Can this engine use any/all capabilities of the VMSpec?

Fuel Used

My VMSpc displays the total miles and fuel used on my coach. I was wondering how the Cummins ECM monitors/logs how much fuel is used and if it's accurate. I calculated by average MPG for the life of the coach and if it's accurate, my Cummins ISC has gotten almost 10MPG over it's life of 6 yrs. and 27K miles.

Power for the VMSpc Box

I just read from another forum that the VMSpc box was powered from the chassis. I had assumed that it was powered from the computer. Since my chassis connector is in a location rather difficult to get to I prefer to leave the VMSpc cable plugged in. So where does the power for the box come from? How much power or current does it use? Would it hurt to leave it on virtually all the time? Thanks.

Engine Diagnostic Connector

I recently purchased the VMSpc from you but I have been unable to locate the diag. connector. I have a 2004 Tiffin Allegro Bus on a freightliner chassis. I know where it is in back by the engine but I cannot find it under the dash. Any suggestions?

Not sure if all gauges are working or should be working

I installed VMSpc today on a Cummins ISL 400 2007 Tiffin Allegro Bus. The following gauges did not provide any information(read 0): oil temp, transmission temp, fuel temp, transmission (gears), horsepower and torque. I am not sure if that information should be available from the Cummins and Allison electronic controls. If it is, how/where should I begin to look for the problem?

ISB 275 with Banks

I have just added Banks to my 2001 Bounder (3/2000 ISB) and it appears that the fuel consumption does not agree with fills. How does the fuel flow/consumption get measured? If Banks Ottomind adjusts fuel feed to injection pump and thus to engine, does the engine computer have any view of this?
The error appears to be several gallons per tank. Is this to be expected? Possible corrective measures? Additionally I presume Banks kit also added new boost sensor for their boost guage -- what does engine computer use in this instance?

Bob Hicks

VMSpc pays for itself, again!

Last year, the VMSpc paid for itself by showing me the lack of power the engine was experiencing was due to lack of turbocharger boost pressure. I confirmed this by hearing an exhaust leak. We were in Alaska at the time, so it was *GREAT* to know what the problem was.

This year, we did all of the east coast, from Prince Edward Island all the way to Florida. While heading east from Las Vegas, our home base, I noitced the oil pressure reading on the Cummins ISB was jumping around on the VMSpc, from the normal 55 PSI to 103. Everything behaved normally, so I figured a sending unit was going south. FWIW, the dash gauge continued to be as worthless as it usually is, as it did not indicate any fluctuation at all.

Eventually, the sending unit got worse, and the information it was sending to the engine computer was either -0- PSI or 103 PSI. When it drops to -0-, the computer cuts back on fuel delivery about 30%. I know this because of the VMSpc, of course! You can feel it on level ground, but it's not obvious. Now, after the computer has a -0- reading for more than about 5 seconds, the 'stop engine' light comes on (this is in addition to the 'check engine' light which comes on when the oil pressure first gets to -0-), and the fuel rate is reduced again. This time fuel delivery is about 1/3 of normal volume, so you have about half of regular boost, and effectively no ability to go up grades or maintain more than about 40 MPH into a 30 MPH head or crosswind. Again, thanks to the VMSpc, I know exactly what is happening. More importantly, I knew I did not need to pull over and pay giant $'s for a tow, lodging, etc. to have a sender replaced which was merely malfunctioning periodically and could be put off as long as I knew what was actually happening.

Frozen Data

I've asked this before but can't recall your response. Recently the data kept freezing and the mouse went crazy and actually rebooted the computer on its own. Please explain again do I plug the hardware into the computer USB slot before I turn on the computer, before I start up the VMSpc software or before I start up the engine? I know there is a certain procedure to prevent this from happening.

Allison selector

It appears that a lot or maybe all of the new Allison selector pads are now supplied with the dual window instead of the single window. I read in a previous post where the new version will not provide any transmission info to the VMSpc, is that still correct? If so in the near future the problem will get worse as new coaches roll off the line. Is it possible that the program could incorporate a couple of files, one for the single window and the other for the double window? Kind of like you have written in the different engine files.

Mercedes MBE 929 Engine File

As promised, here is the engine calibration file for the new Mercedes MBE 929 (330 HP) engine. If you are using this engine, just copy this file to your VMSpc directory. Then select Engine Type and choose this engine.

Mercedes 926 330 hp engine


We recently ordered a new motorhome from Tiffin Motorhomes. It will have the MBE 926 330 hp engine. Does the new version of VMSpc have that engine in it? If so great, if not what can I do to either provide you with the necessry info or contact someone who can provide the necessary info.

(Original Thread: Stop Errow Screen with win XP )

I had the same problem and had no luck contacting SilverLeaf. They tried their best but could not solve the problem. The Bafo web site shows a new BF810 driver Version 1.5 for Windows XP. However, when I download this zipped file, I still got a driver SER2PL.sys Version I then contacted Bafo and they sent me an e-mail with the prober driver attached. They also included detailed instructions on removing the old version 1.3. Properly removing the old driver is very important.

Here is Bafo's response and attached to this reply is the proper driver. Hope this all comes through o.k. If not feel free to contact me by e-mail and I will forward it all to you.

Intake Manifold Temperature

I'm running a VMSpc on a 2000 Monaco Dynasty. What, exactly, does the Intake Manifold Temperature tell me? What should I be watching for with that temperature indication? Is it an indication of the ambient air temp going into the engine?

Top 10 Issues with VMSpc not working
As Of 15-SEP-2004

Diagnostic Plug in front of Coach, not wired correctly.

Diagnostic Plug in front of Coach, not found, was "hid too well".

VMSpc stops "updating" after 3-5 minutes.

VMSpc can not open Com Port.

Bafo USB-to-Serial Adapter won't Install

Bafo USB-to-Serial Adapter already Installed, but Hardware Manager is asking for Drivers.

Bafo USB-to-Serial Adapter drivers not Signed for Win XP.

VMSpc stops receiving data after Update of SW from 2.x to 2.x+.

VMSpc stops receiving data for no apparent reason.

On Boot-Up of WinXP, Mouse is very "erratic", an usually unusable.


Some answers to the above (not a compleat list)

10. and 9.
If the wiring Issues is Power, find a source of Power somewhere in the Dash. If the wiring Issues is Data, if another J1708 data source is located, the Harness can be spliced in. If not, we have made in the past (for a price) 50-60 foot data cables to plug in in the Engine Compartment, and the Owner runs the line forward to plug into his VMSpc or VMS.

Most Windows Lap-Tops seem to be configured to slow-down/shut-down/sleep/hibernate when "not used". "Not Used" being defined as Mouse or Keyboard activity. This is usually a "configurable" amount of time, and most Lap-Tops let you configure this differently for Battery Uses and AC Powered Use, but the AC Powered is usually NOT set to "Never". Which means that if the VMSpc user is "just watching", their Lap-Top, it will stop updating, and sometimes even "freeze up". In some cases, a trip to the BIOS is in order, to keep the Lap-Top awake because of Com Port settings or Power Save modes.

If you know the Com Port is correct, look for Conflicting Software. 4 times out of 5, the User has Palm Pilot, "hot-sync" software, waiting for the Palm to Drop in the Cradle, unfortunately this ties up the Com Port, thus VMSpc is unable to work. The other cases are usually GPS Software or other Com Port using Software.

I am not ever sure with this one. Follow these directions, Manually Removing incorrect drivers (Prolific) to "totally remove" the Bafo Software from Lap-Top and try the install from the Top.

It appears that there is only 2 USB port on a "USB root hub". If the Lap-Top has more USB port, there can be multiple "USB root hubs". The driver only gets installed for the One "USB root hub", so if at a later time, the User plugs the Bafo (or any USB device) into another "USB root hub", the Drivers are not "installed" for that "root hub", so the Hardware Wizard comes up to tell you it needs your help. The Drivers should already be available on your Hard Drive, just not "installed" for the "new" "USB root hub".

I personally have experienced 3 "USB root hubs", for a total of 5 USB ports. 4 USB ports (2 different "USB root hubs") were USB ver 1.1 and One was USB ver 2.0. This would require (technically) three different driver installs, to have the Bafo usable in any USB port on the LapTop.

Bafo seems to have Signed Drivers for XP, now! (Summer 2006).

If the user installs the VMSpc2.1 or VMSpc2.2 package on VMSpc2.0 or VMS2.1, it will erase all the settings, and replace the DEFAULT layout. Martin released a VMSpc2.x Update, which is designed to install over a prevous version of VMSpc2.x.

VMSpc Com Port is assigned Manually from the "Advanced->Communications" menu option. When the Bafo (and I assume all USB-to-Serial adapters) are "plugged-in", Windows assigns them a Com Port, the Comm Port seems to change as the USB-to-Serial adapter is moved from USB to USB port on the laptop (see Toshiba P25-S477 Satellite Lap-Top info below). So if the user, uses a different USB port on the Lap-Top, the Com Port changes, but VMSpc does not look for the "new" Com Port, and thus, does not work. Also on the "Advanced->Communications" menu option, it is recommended to select the "check box" AUTORESTART.

This is very prevalent on Win XP, in the last 9-12 months (2003-2004 time frame). Read "Current Best Procedure, Toshiba P25-S477 Satellite" below. Also Martin just "found out" in the Last Month, that MicroSoft specifically DOES NOT support USB-to-Serial devices, so each Manufacture is on there own to support them, and MicroSoft does not "seem to" care if they work, AT ALL.


P.S. Also, VMSpc Got-Cha... IF you add gages or Move them around, you MUST SAVE your layout, before you exit VMSpc, other wise when starting VMSpc up, it will load the DEFAULT config. Also when creating Odometers, there are Odometer File created, and when the Odometers are Destroyed, the Odometer Files are Destroyed. But if you create an Odometer, and forget to SAVE your layout, the Odometer does not appear on your VMSpc, but the Odometer File are still on your Hard Drive, now Orphaned....


Current Best Procedure
Toshiba P25-S477 Satellite

Plug IN USB to Serial Adapter before Powering up Lap Top from a Cold Start. Plug In USB to Serial into Back Bottom USB port. (Configured for COM2)
DO NOT have VMSpc JIB powered Up, Until Lap Top is booted up to Login Screen.
Power Up VMSpc JIB.
Login and Start VMSpc Window's Program Ver 2.1.

Best Guess of Problem.

There is a Conflict with the Bafo BF-810 USB to Serial adapter when it is receiving Data from the VMSpc JIB. Plugging the Bafo BF-810 in to the LapTop after booting does not seem to help the problem. Only booting the Lap Top with the BAFO plugged in, and NO data coming from the VMSpc JIB is that only consistent and reliable configuration.

Please note that USB devices should be able to be “plugged In” after booting, at any time. This behavior is most likely a “bug” and I will address it to Bafo to see if it can be corrected in Future releases of their Software.

(Note: New Information avalible as of Summer 2006 indicates that WinXP is "seeing" the Serial Data comming from the VMSpc JIB, and thinking that it is Serial Mouse data. WinXP then Opens the COM Port, and prevents other applications for using that COM Port. I have also received one report of this behavour with WinXP and a Built-In COM Port.)

Logging flag

Hi, I have been using the VMSpc for over a year now and love it, particularly the logging function. I have used it on many an occassion to document issues with the coach to help the manufacturer trouble shoot heating issues for example.

My question is this:

Can you add a flag that displays whether or not the logging function is enable or disabled? Many times I forget to turn it off or upon departure cannot remember if I turned it on forcing me to go to the dialogs rather than setting a display flag to remind me in either case.

Another Boost guage question...

Just tried my VMSPC on my 2006 CC Inspire with CAT 400.

The turbo boost was in the "red" at 29 PSI? Seems pretty odd when it will be in the area of 31 PSI when accelerating and climbing hills. Is there an adjustment I should be making? It is already selected for the CAT 400.

But I found the program to be quite interesting.

What are the important guages to have? I have my Delorme software on top, with only a few guages down at the bottom.
