Freightliner/Mercedes VMSpc Compatability

I am considering ordering a Class A with the Mercedes Engine on a Freightliner Chasis.

Does the VMSpc work with this combination ?

Thank you ,

The final release of VMSpc 2.2 doesn't work

I'm using the VMSpc Beta 2.2 software which works just fine with my system. However, I would like some of the extra features such as Horspower gage from the final release but that release won't communicate with my JIB. The software works just fine but it just doesn't find the JIB. I've seemed to try everything but no joy. My JIB has the com port out and I use the Com port to USB adapter purchased from you folks. When I view the hardware through "My Computer", the computer sees the port and the software is set to the same port number but nothing happens. Any thoughts?

VMSpc 9% higher than speedometer/Radar

VMSpc 9% higher than speedometer/Radar, how do I correct?

VMSpc w/ built-in USB (not thru adapter)

Are there any efforts in the works for the JIB to directly interface to the USB port on a PC, instead of using a USB-to-Serial adapter??

I guess this would also take a VMSpc software update, to connect to a USB port instead of a serial port.

Am I asking for too much? ;)

Using a serial connection these days is at least as dated as cassette tapes.

New Computer, downloaded program, connected the USB cord and...

...nothing. Is there something I should set on the computer to get it to work properly? Or, do I need a new cord...this one is three years old.

Thanks.

Boost guage question

Have been using VMSpc for a few years on our DSDP. Just put a Banks PowerPack on the Cummins ISC 350. I changed the setup to the ISC Banks one and found that my Banks boost gauge shows about 32-34 psi boost while the VMSpc never went over 24.3 psi. According to Banks I should see in the low 30's for boost now and that jibes with the gauge. I know I have the ISC w/Banks settings as the HP and torque show the new higher output. Is there something I need to change to get the correct boost reading?

Calculating Fuel Burn When Using Generator ?

Unfortunately (but obviously not SilverLeaf's fault), the generator is not being monitored by the engine computer, so there's no real way to have VMSpc do any calculations for it.

So, how do you other users incorporate the extra fuel burn based on generator usage, and how close do you REALLY get? From boondocking, I learned my QD8000 uses about 0.4-0.5gph by itself, but I can never get a good overall burn calculation from engine and generator together, even though engine-alone burn comes out quite close to what the VMSpc says. With the generator's numbers, my calculations are all over the board - I'm talking maybe 55 gallons one time and 70 the next for a comparable run, which has got to be wrong since there aren't that many hours of usage between fillups.

Somewhere in the garage, I think I still have one of those late '70s Zemco gauge-systems that had a ball-in-race type of fuel sensor, and am tempted to stick it in-line with the generator. Trouble is, it was never that accurate either.

Comments?

VMSpc Torque Reading

I'm using 2.2 on my Cat 3126b and Allison 3000 tranny. Everything works except I'm unable to get a reading for the Torque Gauge. Any ideas why no value being displayed?

Adaptor from Cat to Cummins on Freightliner Chassis

I attempted to transfer my VMSpc, I used with a Safari with a Cat engine, to a Newmar with a Cummins engine and found the plug was different. Is there an adaptor I need to fit the plug on the Freightliner chassis with the Cummins engine?

Parameters

Just installed VMspc in our 2000 Damon Escaper MH. It has an 8.3 cummins 350Hp.Works Great!
I want to have the udible alarms for oil pressure .temperature etc. What value would I use to trigger? What are the operating normal values for this engine?
What or how does the simple guage of relative humity work.
Thank you for your response. Stu............Canada

National Caribbean

Hi,
We purchased a 2001 National Caribbean and travelled the USA and Canada. We then shipped it back to Australia. It has been converted to right hand drive and have had an LPG system fitted to the motor. This has increased fuel efficientcy and given an increase in power.
I now know 6 people who have imported Caribbeans from USA to Australia.
Have advised them of the Silverleaf system and believe would all be interested if they could see a working system on this model.
Nobody has been able to find a front data link. We have found one tied in a loom, above the gearbox. This will be brought out to the rear compartment that houses the 12 volt electrics, inverter gearbox and LPG computors.

front port on 2005 Freightliner XC chassis

I don't have 12VDC on the front dash port. The engine port works fine. By jumping another 12V source in the dash, I can get the JIB to work. Do you know if there is a switch somewhere on the XC chassis for the front port power?

thanks

Is my Engine/Tranny is PID-ling on me ?

Hi -

I hope the title caught your attention.

Now for my question... What the heck do all the PID codes mean that I'm getting, and where are they coming from? I have a VMSpc connected to an '06 HR Endeavor with the ISL400 and Allison Transmission, and I randomly (as best as I can tell) am getting a whole lot of codes, see atachment, but can't find out anything anywhere as to what they are for/from or a decoder to define them. Can anyone help?

Thanks in advance!

Fuel Level Sensor

Does the fuel level sensor work with the VMSpc? If so how and what's the cost?
