\'Official\' fuel economy

Did 27mpg from London to Edinburgh when I first got mine, which came as quite a surprise.
Needless to say, it is in the low teens now I\'m using it for pottering about town. Worst so far was half a tank driving St Andrews to Edinburgh (about 75 miles) but it was the greatest hour of driving I\'ve ever done

After my retune with negative lag and a really lean cruise my FD does 29-30mpg.

But its only possible if you stay under 0bar boost for most of the time.

Does a lean map for cruising carry any risk/detriment to the engine?

Sorry, but what does negative lag mean? :o

Mine was averaging 17 mpg for pretty steady road use before i took it apart. Can only imagine if you\'re heavy footed it will be well below 15 mpg.
 
Will be interested to see how low my mpg goes when it becomes a track car next year :chat

I\'ve not emptied my first tank yet. Sat on the 1/4 line marker after 360km. Drove most of the way back with a boost leak though it seems as I had a poke around the bay the day after I bought it and one of the pipes was fair loose!

Now it\'s boosting properly to 0.8bar though its dropped quite quick lol

I dare say 37mpg was achievable - but I very much doubt anyone else will get that figure. There\'s hardly any standard FD\'s about, and those that are are between 10 and 20 years old. I don\'t think you can compare with what was probably a brand new totally standard car.
 
Anyway, to reiterate what\'s already been said - who cares!

According to Japanese Performance magazine this month, the rotary is at its most efficient at 150mph

You know what to do gentlemen...
