I think its understandable some people are upset about having to leave their new car in the dealers for a week whilst a part of it is shipped to jersey to be rectified. The car should never have been relased with this problem in the first place. Put yourself in the position of a new owner of what is their pride and joy and you should be able to empathise with that.
Lets hope they dont lose any ECU's in the post or you will have dead STi's in the dealers for weeks.
In the UK, when people buy a PPP upgrade, Prodrive ship a new ECU to the dealers in advance, the original ECU is then shipped back to Prodrive for a reflash. Fitting the full PPP which includes a performance cat, backbox and some minor pipe changes takes less than 1 day. The dealer is fined if they take longer than agreed to ship the original ECU back. (that means they never do fail to ship them!)
