Re: Power Commanders?
To be honest most places that know what they are doing don't tune for a certain fuel air ratio but max power, which is obviously the optimum A/F mix for that engine. That is really the only way to get an engine running well, as Chris says. The engine pulls in a certain amount of air. Not giving it the right fuel for the air pull is just daft.
What a power commander does that people seem less interested in is tune each throttle position for all revs. So you might have a stock bike that at max throttle runs near perfect but under 10% throttle runs crappy and so to you have to run with more throttle to get the same performance a well fuelled engine will get at 10% throttle. By making all throttle positions fuelled right your engine shouldn't need as much throttle to produce the required power... So you should see am improvement in fuel economy simply because you use less throttle hence less fuel.
Hope that makes sense...
