Don't know if this has been brought up before?.. But I find it amazing the way the 290 responds to driving habits! I mentioned in another thread, that the 290 boss has good days & bad days. By this I mean, If you have given it stick for a while, the engine actually goes harder after! The "camminess" at idle also becomes more pronounced! If you have been sedately cruising for long periods, it becomes "mild mannered". I noticed in the days after the FPV day at Calder, ( where it was on the limit constantly), that it turned into an absolute beast! Even the average Lts per 100ks confirmed this. Before Calder was always hovering around the 15's Now working its way down from 21. Does seem that the management system learns driving habits & adjusts accordingly?
