Once you get past the secretary dave is great. Best time to ring is between 9 and 10, as he doesn't start mapping till then.

If you stick it on the live adjustments screen - f8 i think, you can make on the fly changes, have you read the manual?

The K3 also does adaptive mapping, just take it for a drive check the results, upload them and take it for another drive. A couple of goes and it's normally pretty much spot on. Obviously you start at the low load sites.
