Want 2 upgrade exhaust system for a Vulcan 900 Custom (Is a fuel management Fi2000R really needed)?

Question

I called my local store to oder a exhaust system but the rep said that if I change the exhaust pipes then I will HAVE 2 get the Fi2000R fuel management controler.

Is that ture?
What happens if I just bolt the pipes with out the Fi2000R?

Answer 1

ur mix might be off enough to make the bike run like ****. for best results, after the pipes, the higher flow air cleaner is also installed, the air/fuel mix is properly dialed in for the set up, and for all this...u get about a 15-20% increase in horsepower. its what they call the 'stage 1'. it's typically the 1st engine mod owners do.
not all pipes are the same. to run straight pipes without having the mix properly dialed in for example, it will cause the bike to run too lean...almost lean enough to cause engine damage.

Answer 2

Due to EPA regs, your bike is probably already lean from the factory. Adding pipes that increase air flow will only serve to exacerbate the problem.

None of the current motorcycle F.I. systems that I am familar with have mass air flow sensors so they have no way of knowing that air flow has increased. Think of them as sort of a 'dumb' system. They operate on pre-set parameters inside the ECU and will do so until told to do otherwise. That's where a Power Commander, the Cobra Fi2000R, the Techlusions, etc, etc, DFO's (digital fuel optimizer) comes in.

A Power Commander will actually change the mapping inside the ECU and allow changes in many facets of the F.I. system. I.E. injector off-set, fuel flow, ignition timing, etc.

A DFO simply alters the signal from the ECU to the injectors allowing you to make more simplistic changes to your fuel rate and flow.

Either will work, it just depends upon how involved you want to get with your engine management system and how big your budget is. But chances are, your going to need one or the other.

Install the pipes, do a plug check & watch your fuel milage. If the plugs are very light colored and your fuel milage goes way up, your lean. Performance will suffer, damage could occure. Which when you think about it, defeats the whole purpose of installing the pipes in the first place. Right?

Answer 3

He is trying to sell FI200R I would say. Your bike is fuel injected, when you change the pipes you will run lean and not get any improvement from the pipes other than sound and you will also have the problems associated with running lean....especially if you have a K&N or like air filter. I recommend the Power Commander because of tunability and the way you can make changes (which you likely will) to your engine and just retune, but there are many such products out there some, like chips, are set and some you can program. Also, if not already, I would change the intake to free the flow in as well as the flow out (i.e. your new pipes) and use whatever product you choose to change the map of the injection system.

If you are bolting on a full exhaust system do you HAVE to get a fuel control?? The answer is NO.

I have to ask why not? You just dropped a bunch of money on a full exhaust system. To take advantage of any power added and to make your bike run better you will want a power commander. I believe the sales guy to be correct that you want the fuel control just don't buy the Fi2000R; it is a piece of crap. get a Dynojet Power Commander III USB

The bike will NOT self adjust like a car and the power commander will get the air fuel where it should be. When you put the pipes on without a fuel control it will backfire and run a little rough but you can run it like that.

When a power commander is removed the bike goes back to original settings.

They are easy to install and take about 20 minutes.

You can get it as little as $254.96 shipped

Don't believe me look around at the reviews on the internet. The Power Commander is MUCH MUCH better.

Answer 6

I have had about 20 motorcycles in my riding career so far, and never once installed the F12000 (or any other fuel management controller for that matter) on any of my bikes after bolting on aftermarket pipes. Furthermore, today's motorcycles are smart enough to auto-compensate for differences in mixture, due to elevation changes for example, without needing one.

A fuel management controller ALONG with the pipes may increase the overall efficiency and eventual power figures, but it is NOT necessary. Remember that the guy is a salesman first, and tech 2nd. Just use the pipes and you won't be missing much. Cheers.
