The more and more I read on aftermarket exhausts and remapping.
the more and more I believe that "dyno" tuning and all that is a complete wank.
And generally a little gimick so that bike "experts" can make a quick $1000 (aus) for about 3 hours work.
After all, in my understanding of it, a "dyno" run, just gives you a read out of your bikes rpm/torque/HP.
Heres one I found just then
Most dyno runs, should give you a similar result for that bike.
So that removes the need to do a costly dyno run, just to get two lines on a piece of paper.
The remapping part. is designed to remove the "dips" that manufactures put in, to pass DB noise levels..
the FZ6, has two. as seen in the graph above.
6000 rpm, and 9000rpm, anyone with an Fz6 will know this.
As for fitting your new exhaust, if its slip ons, and it starts. and you can ride it, your bike is working. there is no need to remap it.
Maybe, if your keen, and have truck loads of cash. the gain of a few xtra HP is worth it.
but I doubt anyone ever gets the full potential out of their bike. let alone 3 - 5 xtra Ponies.
Unless your some sort of freak racing guru, in which case, why are you reading this, and not lineing up on the MotoGP grid with Fiat as your major sponser.
Another arguement to back this up, is the O2 sensor.
your bike will not magically stop working if you go for a ride from sea level to the mountains. the O2 sensor will compensate for this.
From what i understand, the only time a remap is needed, is when you change both exhaust and air filter.
