I intend to install a MGP computer in my '88 Westfalia. This is an opensource project found on the EdoModder site, here
http://ecomodder.com/
The specifics of the unit to be installed are here
http://ecomodder.com/forum/showthread.php/mpguino-release-one-workspace-2115.html
In essence it needs a signal from a fuel injector and a Vehicle Speed Sensor signal.
I assume the VSS signal could be taken right off the back of the speedo since it feeds the cruise control.
Any suggestions where to pick up the signal for one fuel injector?
Any one else seen this project? I think it will make a neat mod for the Westfalia.

How is that anything like a MPG computer?
does anyone else have any experience fitting a trip computer to a Westfalia? The problem is, all commercial aftermarket units need the OBD socket - which of course our vintage vans do not have.

No knowledge that could help you go through, but sounds like a really cool "poor man" scangauge.
I look forward your installation report and calibration data to start mine

Shouldn't the unit need manifold vacuum too? The fuel pressure regulator will vary fuel pressure based on manifold vacuum, so to know how much fuel you're squirting into the cylinders you need to know manifold vacuum, and injector pulse width.
Looks like a cool idea.
