does it run OK afterwards? if so, maybe the startup (cranking) fuel settings are way off - is the smoke black (fuel) or blue/white (oil)?
The MegaSquirt EFI (that i'll be using soon) has priming pulse to the fuel pump on igntion key to on - and it starts injecting with an enriched fuel mixture when cranking starter motor- and stays enriched until revs hit user-defined point (e.g. engine running) - if that''s too high, you run very rich until the ECU works out you are not trying to start the engine. That kind of problem might produce a bit of smoke.
Does the manual for your ECU say anything about startup settings?
