Fuel injection questions - -

[thomas walter x5955]

Didn't realize my comment about *thinking* of pressure sensors
to determine the closing the number one valve could generate
so much interest.

For a HOME BREW system, I would use a sensor to check a cam lobe.
For a production system, once TDC is determined the rest of the system
could keep track. Just the idea that, perhaps, a MAP sensor and a little
software (DSP) could be used in place of an electrical-mechanical type
sensor.

P.S. For those Home Brew solutions... do not over look a fuel pump
lobe on the camshaft. Nice part about using that, is there is a nice
little cover plate that is easier to modify than a valve cover. ;-)
