CAT 3208 monitoring

I thought you guys might like to see the steps required to add a Fan Speed gauge to VMSpc.

First bring up the VMSpc Parameter Editor. Here's a snippet of the editor:



For my Fan Tachometer I'd start by choosing a similar PID that VMSpc already understands. In this case I chose "Engine Speed". This means I'd use the same J1578 encoding for my Fan Tach as is used by the Engine Speed PID 190. Now all I need to do is define the new PID value and assign the gauge min, max, red line, and yellow line values. In the snippet below I arbitrarily chose PID 255; I'm assuming there's some proprietary PID space available, maybe a bad assumption. I'm also assuming that what VMSpc needs to know to decode the PID is described in "Format", "Offset", and "Multiplier", which I left unchanged from what's used for "Engine Speed". This needs to be verified:



Then under Gauges I select "New Simple Gauge", choose "Fan Speed", click "left alignment", and click "show gauge name", "value, unit", and "graph":



And here's my gauge:



This may work assuming there's some proprietary PID space that I can use, also it needs to be verified with Silverleaf.
