VMSpc on an 8V92

[Don Bradner]

I've been wanting to get the VMSpc that I had on my SOB working on my Bird, but
there is limited info available. Leroy Eckert has recently purchased VMSpc and
had similar questions. Together we worked out what needed to be hooked up, and I
have mine working. Since the connector is virtually unavailable I hardwired in
behind it.

Yesterday was the first time I could test it while driving (just a couple of
miles). I had a lot of gauges setup to see what showed, and what didn't. The
working list is:

Coolant temp
Engine RPM
Vehicle Speed
Fuel Rate (GPH)
Oil Pressure
Accelerator Position (%)
Battery Volts
Fuel Temperature
Engine Load (%)
Engine Hours
Cruise setting
Turbo Boost Pressure

Not much from the transmission, although speed is presumably a passthrough. No
temps, or odometer readings.

Among the items that the DDEC should put out, but VMSpc does not have a standard
gauge for, are Coolant Level, and Oil Temperature. If I can find the necessary
PIDs for those I can see if they work or not.

At some point I will take some pictures of the connection and put together a
short article to upload to various online files sections.
