Thought I'd try V power.

That's interesting regarding the ignition advancing. I suddenly thought of it ahead of what you were saying about a slower, more controlled burn VNA. My 1000 actually has a 4 degree ignition advancer on at the moment which I had forgotten about - this could help to explain the bikes preference (in my own opinion, please don't shoot me) of the higher octane fuel.

It's also worth noting that some ECU's take a while to learn what is going on before they make adjustments - my cage is said to do something along these lines. It's not enough to make a subtle change and go for a spin. With V-Power though, the car definitely gets some better MPG - its not enough to outweigh the cost of the fuel, but that's irrelevant to me. This has been tracked across 10k miles with earlier records using standard fuel (95 RON). The difference in my engine is up to about 10% which is only about 3MPG though...
