| All the current road tests in magazines (and ones going back a few years too) rave about the quality of a standard Dukes fuelling. Admitedly this is a view from the saddle rather than a view of the fuelling graphs and dyno charts. But then, most people get more fun from riding than looking at graphs don't they?
I think that this is because Ducati development engineers and testers will have spent thousands of man hours getting the fuelling right (even allowing for emissions testing).
Now I know that fuelling changes when you change anything else to do with the induction or exhaust, but once again some nice people with white coats and calculators will have spent many hours of testing to get a replacement chip (or ECU) up to scratch for Termis or freeflow airfilters. I don't know who is best at doing this, DP, JHP or FIM, but if you look at the FIM website you'll see the sort of attention to detail that goes into it.
When you couple that with the fact that once the firmware is sorted to the point where it's nearly there, the ECU will automatically make minor tweaks from all the sensor information it gathers.
So, I agree with what Weeksy is saying (even if he is playing devils advocate). Any extra gains from a Power Commander are going to be pretty marginal over those of a well set up pipes/filters/chip combination. Gains, that as Weeksy said, will go largely unnoticed by all but the people that truly can wring out the last drop of performance from a bike.  |
