Cold start is implemented quite nicely.  The number of pulses is configurable
as well as the threashold temperature (based on coolant temp).

yes, this would be nice.  Not really a huge deal, it just means that there
will never be compensation for high electrical draw like the radiator fan or
direct motor draw from the AC (if you've got it).

Well, you can adjust the open loop fuel enrichment gain across the board
based on coolant temp.  The limitation you might be thinking of is the fact
that 034 does not go closed loop until X seconds (configurable) regardless of
if the engine is warm or cold.
