On US sites there's stuff about the IS300 having an adaptive ECU that learns how you drive and optimises fuel efficiency/performance for your style of driving. The theory is that it just learns once so if you buy 2nd hand or change how you drive you can re-optimise by resetting the ECU. Easiest way to do this supposedly is to remove some fuses for 10 mins. Then it re-learns. If this isn't complete rubbish does anybody know if it applies to the UK IS200 (manual) too?

I'm giving it a try. There seems to be no noticeable difference in performance but I'll check fuel consumption over the next couple of weeks to see if I get an improvement.
