Questions about Silverleaf VMSpc

belfert · January 17, 2010, 03:41:07 PM

I got my Silverleaf VMSpc working today. I had an issue the last time I tried it because the driver was not installed on my computer.

Anyhow, I am using this with a Series 60 DDEC III. I am not seeing the intake manifold temp. It just shows zero. Is that correct? The turbo boost also shows zero, but I assume that is because I had the engine idling at 1000 RPM. I can't drive the bus right now.

Why would the mileage in my DDEC only show around 10,000 miles when I have driven further than that personally? Does disconnecting the battery reset the DDEC?

Brian, DDEC has a separate gauge for manifold temperature. Use the PID sniffer in the adavanced option with the engine hooked up (does not have to be running) and you will see all of the gauges you can create. You will see "air inlet temperature". If you click on it, you will then be able go to simple guages and set it up. Once you do, you should see a temperature that is somewhat close to ambient.

Not sure about the mileage. You should be able to set the odometer to "start from day one" and that should be the reading on the ECM. Once you do that, you will probably want to lock that gauge so that you will not mess with it. You can then set up other odometers for things like day (reset each day), trip, and fuel (reset at each fuel up).

One other thought, you should probably set your engine to some Series 60 that is close to your rating. I think that will make setting up the gauges easier. You do not need to do that, as you can always use the PID sniffer (really powerful tool).

The program automatically selected the right engine. 500 HP is the lowest HP setting for the Series 60 and that is what it selected. I guess I assumed it would only display things that the Series 60 and DDEC could provide data for. I'll have to read the manual again and play with it some more.

I have no idea why it showed a red alarm for voltage because when I brought up the voltage display it showed a good 27.54 volts.

The mileage from the DDEC isn't really a Sliverleaf VMSpc issue. I am sure it is a DDEC issue. I just don't understand why the mileage is less than I have driven so far.

I am not sure what it would take to "reset" the miles. You can't do it with a ProLink and it will not reset itself even if it does not have power for months on end.

Are you sure that the DDEC mileage is wrong on the ECM? Would need a ProLink type reader to see the actual ECM mileage.

I am pretty sure that the mileage and other data is considered to be something like a speedometer and must be "tamper proof". The only time I know of when the data is "zeroed" is when the ECM is replaced.

I too wonder why the voltage is showing red at that value. I have not played with VMSpc on a 24V system. I wonder if it thinks there is an over-voltage situation?

I don't see how the VMS picked the right engine 500 hp for 11.1 is a little much.

good luck

500 hp is the lowest rating for the Series 60 they have on the list. I am only at 350 hp.

When you drive the bus you will more than likely find the silverleaf is not reading the correct speed. Your ecm may have to be corrected for the counts for speed.
