Interesting!

Another way to do it would be to approximate it. You can get the tach signal (as I said, you'd have to filter it) and add a manifold pressure sensor, or possibly two sensors--one in the manifold, and one in the air cleaner. You should be able to approximate the fuel flow through the carburetor if you know the pressure differential across the metering nozzles in the carb. You might have to add a throttle position sensor to work out accelerator pump volume.

Heh, basically you'd be doing all of the calculations for fuel injection without actually powering the injectors.

Looks a lot like a Tatra from some angles.
