Rob, 

This is a theoretical approach, and IMHO it won't work!!!

There will be more variables to consider. Battery voltage, water
temperature, humidity, etc etc. The problem is that although you may get
within striking distance, you would be better off building something,
generating the mapping system and then mapping it on a dyno, either chassis
or engine. That way you actually generate the numbers the engine wants and
not the theoretical ones which are only ballpark, and will need mapping in
anyway. 

If you do not have access to a dyno, use an oxygen sensor, there is a thread
running on them right now. Just drive around and tune it that way
