Just re-reading the comments in this thread ...
In a previous "life" I designed powertrain control systems. While I did not work directly on this portion of the "system" (software) a good friend did. He explained to me the EXTREME amount of engineering involved in order to fire the injectors and spark plugs in LESS THAN 1 REVOLUTION OF THE ENGINE once the starter was engaged. Trust me it is quite complex ! The computer is not fully "synced" with the engine until TWO FULL REVOLUTIONS when it knows, from camshaft data, exactly which cylinder is coming up on compression.
