Yeah it's quite mad Chip! It's the benefit of direct injection and a few other things - it does of course have downsides too - prone to misfires, although this can be helped by the way the fuel is delivered. Condensate in the exhaust is also a problem as temperatures are so low. You can only get away with it running so lean at low load, but typically lambda 2-3 is achievable at most sites
Will have a chat about it at the next meet we're at Chip, it's pretty interesting
