J1939 Transmission Data

I have a 2006 Monaco Windsor with the Cummins 400 ISL. Under the dash is the 6 pin diagnostic connector. As is well documented on this site, no transmission data is revealed by VMSpc when the 6 pin port is used. If I understand these systems correctly, the transmission data is sent over the J1939 bus and the J1939 data lines are not present in the 6 pin diagnostic port. Inside the dash there appear to be other electronics that use the J1939 data lines - the Beede Instru-Link and the Aladdin J1939 Bridge. Can I simply tap the J1939 data +/- lines and supply these to pins 5 and 6 on the VMSpc module?
Another possible solution may be in the foreward electrical bay driver's side foreward outside. There is a 9 pin diagnostic port labeled 'TRANS'. This would be a little more complicated routing from outside the coach to inside.
On this coach the 12v power is constantly on at the 6 pin port and switched at the 9 pin port. Can the 12v power to pin 7 of the VMSpc be derived from any convenient switched source instead of coming from the diagnostic port?
What is the purpose of pin 8 (Headlight Switch) on the VMSpc?

Thanks,
Doug

switching from notebook PC to android tablet

Will the VMSpc JIB drive the new bluetooth module? (Note: I have the orig JIB w/RS-232 D connector). What do I need to make the switch from a notebook PC (Windoze) to an Android tablet? My motorhome is a 2004 Freightliner XC chassis with a Cummins ISB2 & Allison 3000 trans.

interpreting Diagnostic History File

I have had several Stop engine light events that only last about 5-10 seconds and then go out. On printing out the Diagnostic History file I get a lot of information that should be useful if I can find what they mean.
The heading information that are obvious are ENG, TRN. What does the heading SRC and MD mean? I assume TPE is type, is that correct? What do the following codes mean, SID, PID and SPN? When it prints out ID codes that are not Cummins or Allison codes where do you find the information to interpret the codes. I have had several 5 digit codes that Cummins and Spartan don't have information on. They are 64208, 24287, 25983, 93567, 6, 1656, and 2047 among many others. My engine is a Cummins ISC 425 with an Allison 3000MH tranny. Any help getting this information would be greatly appreciated.
Thanks

93 Eagle DDECII / Allison B500 World

I have a 1993 Eagle Bus Conversion with DDEC II and an Allison B500 World. I purchased the JIB with pigtail from RVUpgrades a few weeks ago. I'm getting the dreaded PC Port Failure and Failure Between JIB and PC. I don't have a 6 or 9 pin connector so I'm connecting to the Chassis ALDL. The power to JIB is switched. Its "Ok" in Communications dialog until I turn on the Ignition switch. I have 13.5v on red (when ignition switch is on), black is grounded. White wire is fluttering at 4 volts and green at 1 volt. I'm using the J1708 wires on the pigtail. In VMSpc it cycles through Starting, PC Port Failure, Ok, then repeats in communications dialog. Eventually I'll see the Failure Between JIB and PC. I have green light on JIB. Red light blinks twice at a 1Hz rate then waits 2 seconds and repeats. It behaves the same on two different laptops running Vista. I've searched the forum and checked everything I can think of. Attached is one of the raw logs I captured rawlog3.zip. Hopefully that will help pinpoint the issue. Thanks in advance for reading and any suggestions you may have.

Fluctuating voltage

While driving my voltage showing on VMSPC fluctuates from 13.2 to 14 volts. It reads 14. - 13.8 - 13.6 - 13.4 - 13.2

Each voltage seems to hold for about two seconds.

It is pretty regular and I am wondering if it is just the nature of VMSPC or do I really have such a wide fluctuating voltage while driving?

Oil Temp on Cat C7

I cannot get VMSpc to read Oil Temp. Any suggestions?

Concers...

Is all OK with Silver Leaf.....just sent and e-mail to Lori and got a bouceback.....

My engine is not in the drop down, which should I select?

Just received my VMSpc in the mail yesterday. Thank you.
I was looking in the advanced tab of the software and noticed that the Maxforce 7 engine is not a selection. I have th 260hp version. Which engine should I be selecting instead?

Thanks,

mileage correction not working

software will not allow me to correct the mileage. I can select the current mileage but it will not allow a correction. The mileage shown was not entered by me and popped up when I first loaded the program.

Removing old data

I have a new coach and want to delete the old data from the old coach. I would appreciate any suggestions.

After Market Can Nodes

I am working on aftermarket Canbus nodes for RV''s that don't have Can .
once I get the info i need to spit data out through WSP hardware, I will be offer some notes per the RV-C spec that you can use.
The nods use the Maple STM32 development board for building and testing.
It has a Can bus built into the board.
The hardware is in a Din Rail Enclosure for mounting.
BTW I have a 1950 Fageol that has 32 Can bus nodes I built.

Cat 3126E diag. codes

Can I clear diagnostic codes stored in the computer with VMSPC?

Running VMSpc on a netbook, 7" screen

trying to run VMSpc at less than full screen so I can run Streets & Trips at the same time.
VMSpc ALWAYS opens in full screen and clicking on the reduce button does nothing. Also tried grabbing the screen border and dragging, still no change.
I'm using the latest release of VMSpc and Windows XP. Other programs can be run partial screen.

6 pin connector does it work on cat and cummins? thanks

Battery Voltage Fluctuates

My voltage is constantly changing. It goes from 13.4 to 13.6 to 13.8 to 14 volts in an endless cycle.

Is it just a timing issue and would there be a way to adjust the sense speed?

Battery Voltage Parm file bug

On my VMSpc the unit for battery volts (V) disappears. I have determined that it is probably a bug. What happens is that the unit for the first gauge in the parameter file, which is usually Battery volts, dissappears. As a work-around I created a dummy gauge called Amps. Since it appears before Battery I can now enter a V for units and it stays put. I've reported this to Mark.

Default metric workspace

In the VMSpc instructions there is a mention that the display can be modified to show information in metric. I started switching some of the parameters and it appears that the only way to do this is one parameter at a time. Does anyone have a default workspace (in metric) file that they would be willing to share in order to save me and other users the tedious work? I'm wondering if SilverLeaf could create and post such a file on their downloads page or include it in their defaults settings distributed with the application.

Strange numbers in odometer window.

I am a brand new user of VMSpc and there is definitely a possibility that this is a user problem. When I connected my VMSpc to our RV, I get readings of 4,278,693.0 miles, 232.0 gallons, 45:24 time, 94,244.3 mph, and 18,442.6 mpg in the odometer window. The RV has roughly 44,000 miles on it so these numbers are kind of off the wall. The odometer shows completely different numbers. I triple checked our engine settings to being Cummins 8.3 ISC 350. Any suggestions?

VMSpc Version 2.5 Build 10.... Released!!

Some people using the USB JIB ( JS-501 ), have experienced a Program Crash when accessing the "USB Advanced JIB Properties" Dialog Box.

We have been able to Replicate this issue, and we have resolved the problem with Version 2.5 Build 10.

Also, included in Version 2.5 Build 10, is support for the "Maxxforce 10" by International®. There are two parts to this support, the Engine Parameter File, and the addition of support for PID 158, "Battery Potential (Voltage)—Switched". The more common PID 168, "Battery Potential (Voltage)" does not appear to be supported.

If you have a Maxxforce 10, you will need to use the "PID Sniffer" to scan for all the provided PIDs, and ADD PID 158 to the VMSpc Parameters. You can use the Formats for PID 168 for your "template". This would be in addition to selecting the Maxxforce 10 Engine Parameter file.

The above PIDs are the domain of the SAE, their mention is for clarification purposes only.

Cycling milage within Trip meter

For the past few fuel fill-ups I have noticed the mileage reading in all trip meters continually cycles between 0.0 and 4.9 mi when I initially reset the trips and fuel minder at fill-up. This "difference" continues to display, cycling from the true mileage to a value that is 4.9mi higher as the millage increases. Why and where is this phantom 4.9mi coming from and how can I get rid of it? Consequently the MPG reading within the trip meter cycles between values at the same time.

Cruise set speed and Cruise status indications

Having fun with my VMSpc, except for the cruise indicator gages. Cruise status will indicate "0" when cruise is switched off, "1" when it is on and "129" or "133" when cruise is engaged. Anyway to get that to read "off", "on", and "engaged"?

Cruise set speed reads either "0", or the actual set speed, but there is no consistency on that indication and when it does indicate the speed, it is only momentary, then returns to "0", even though the cruise is engaged and working.

Any suggestions on how to correct this issue would be appreciated.

Reflash of JIB cured trans gauge dropout, but now turbo gauge drops out.

I had my USB JIB reflashed while I was at the FMCA rally in Albany last month. My trans gauge which was dropping out all the time was fixed by the flash. But now my Turbo gauge is dropping out about %50 of the time.

Any guesses on the fix for this one?

Thanks, Marty

Fuel Minder

I have had the VMSpc for a couple of years but only recently used it consistently on a cross country trip. I calculate fuel mileage. On this trip I compared the Fuel Minder (Fuel Used and Fuel Remaining) at each fill up. Consistently the fuel added is higher than the fuel minder reading. Example: Fuel Minder reported I had used 47 gallons but I pumped 57 gallons) This also makes the MPG appear higher on the VMSpc than my calculated.
Is there a parameter I can play with to adjust so I can get the calculated readings and the VMSpc closer.

Upgrade from build 2 to build 4

I just saw that the current build for VMSpc is build 4 rather than the build 2 I have installed.

I have an older serial jib using the prolific driver for the usb connection to my W7 64 bit pc.

I am not having any issues with my current installation and would like to know what advantages does b4 have over b2 and should I upgrade or stay with what works?

Windows 7 Driver for VMSpc

Can you send me the driver needed for Windows 7?
I have the USB to Serial adapter purchased from SilverLeaf. Been using the windows XP driver on an older laptop computer. Purchased a new laptop that uses Windows 7. Using the latest version of the VMSpc 25b4.
Can not find the driver on-line. The Prologic site will not return a driver for the adapter.

Thanks William Fuller

VMSpec_USB software updates

I am running the VMSpc software on an ASPIRE One netbook with the v2.5b4 version installed. Is the software titled VMSpec_USB_2011a.zip intended to be an update for this software or for some other application or hardware?

Engine file for EPA 2010 450 HP Cummins ISL engine

Recently purchased a 2010 Allegro Bus with the new DEF engine. The only engine file I find in the software is the one for 425 HP Cummins ISL.
Also When I use the PID sniffer I ONLY have about a dozen PIDs showing, I think there should be many more what is happening or what am I doing wrong?
This is my fourth coach using VMSpc, pretty sure it is not a hardware problem.
The only other difference, it is on a Tiffin powerglide chassis with the Aticia electrical system.
