I doubt it, too.
I don't think the dealer would need to encode the dealer number on the ECU - the factory knows where they sent the bike.
The bike is fully assembled at the factory, and run. They then pack it up for shipping, where some disassembly is done, and I doubt they would go through the trouble of 'locking' the ECU, for the dealer to 'unlock', but I couldn't say for sure.
I helped my dealer uncrate a Rocket and Speed Triple. The rocket needs some stuff put on, but the S3 is pretty much ready to go. They figure 4 hours average setup time, but its more like 6 for a dressed Rocket, and 2 for the S3, including pre-service and test ride.
BTW - these bikes come in a wooden crate, and use 2 to 4 tie-down straps to anchor the bike in the crate. They're pretty decent quality straps, and the dealers usually end up throwing them out. My dealer has a cardboard box in his parts department - "Tie-down straps - $3 each".
