I wanted to get a few more miles on the bike with the fi2000r installed before I posted; but bein' a trucker between the rain and my company believing if I needed a life they'da issued me one (wait!! sorry, flashback to my army days lol) anyways I'll post here cause the Fi2000r is a *definite* performance improvement (and a substantial one) over the stock bike with just the cobra pipes and no fuel manager.

I would have to say for me the main thing was low-end/off the line performance improvment. The company says that with the 2000 the bike "pulls like a freight train right off the line" - well - lol not sure I'd go with the freight train analogy, since I'm sure freight trains pull pretty hard off the line :), but the bike really DOES pull better off the line, and to me feels much smoother thru the entire powerband with the 2000 on there.

With the stock bike, as many posters to this forum have noticed, the bike runs cold for awhile and can be a little balky off the line; with the cobra pipes added but no fuel controller, to me anyway this tendency was made much more noticeable. Even when hot the motor wanted to lurch when you left a stoplight sometimes, if you didn't keep rev's up a little and/or be real careful letting out the clutch.

Now though, you let the clutch out; easy or no, and it pretty much grabs and want's to start rolling. This may be a small thing, but it really made the ride more pleasureable for me.

On acceleraton the motor feels and (to me) SOUNDS better - I'm not sure how to say this, but it sounds like I can hear both cylinders now firing smoothly in sync, whereas before it kinda sounded and felt almost like I was ridin' a big ole' single-thumper (hate to date myself here but, anyone else remember the days of the BSA Gold Star :)? God I used to love my old Lightning and Gold Star :)

At highway speed, with the fi2000 and the cobra pipes, the exhaust note is beautiful - kinda low, not real loud but steady, sweet and deep. Must sound beautiful to people you pass.

I haven't got enough miles on it to tell if there's any change in how cool/hot the engine runs, but when I get some more miles on it, hopefully a lot this coming Monday/Tuesday/Wednesday - if I can tell anything more that I think may be useful I'll post 'er :)

I always thought that you would really need the fuel control to get the full performance from the Cobra pipes... But the PCV (Power Commander 5) with the Auto Tune (AT-200) would be (IMO) the best way to go (BIG BUCKS). This way any changes that you make to the bike are automatically adjusted for. The Fi200r has to be manually adjusted if you change the intake system... which means your going to need a DYNO...

Of course, this is just my opinion...

I partly agree, but the "seat of the pants" dyno is worth something at times I guess.

Dyno guy suggested one or the other ...

When I talked to a tech at dynojet he suggested that unless you were making lotsa engine changes, often, in which case the autotune would do the trick, that otherwise put on your pipes and intake and get it dyno'd and forget about the autotune.

I'm not sure how I'm going to handle it when I put the S&S teardrop aircleaner on the bike; I got it about 10 days ago. gonna try and talk to cobra tech tomorrow (monday) and see what they suggest. Wanted to run the bike stock with just cobra pipes and the fi2000r for awhile to see how it felt, but can't hold out much longer on replace fugly oem air cleaner with the S&S - I think I"d like to dyno it, but the local performance shop/dyno-tuner when I talked with them on the phone said they'd never seen the fi2000r and weren't sure exactly how they'd measure it for performance on the dyno. I'm not really sure what he meant; I'll be talking to them again after I talk to cobra tomorrow.

A little worried at first

I installed the cobra swept exhaust system and the low and mean air intake without adding any fuel management system. After a couple of seasons I broke down and bought the cobra fi2000r. When I rode it home from the shop, every time I shifted gears it was backfiring and there was severe backfiring upon deceleration at high RPM. About 20 minutes into the ride the backfiring on shifting stopped but not on deceleration. I experienced the same symptoms the next two rides and thought it may be defective. I gave it a couple of more rides to "settle in" and the end result? I am absolutely thrilled at the power gains and all the backfiring on shifting and deceleration are completely gone. My two cents - it's an awesome product!

Hey brad, new fury owner and just got the same cobra fi2000 programmer. What is the best settings on the unit?

yes.with intake and exhaust that is a good place to start.

Also I couldn't fully open it up. Does it surpass the 100mph limit with the programmer?

I don't believe the Cobra systems are designed for that. I believe that would be the DynaJet Power Commander, but I could be mistaken. But the Fi2000 does not remove the limiter.


Don't get mad, get Furious!

Fi2000 would monitor the fuel/air ratio and the power commander would cut off the limiters. Would that be right?

The Fi2000 PowrPro does 'monitor' the effect of the automatically and constantly adjusting air/fuel ratio to achieve its best performance.

The Fi2000R has manual air/fuel ratio adjustments but does not monitor air fuel ratio.

The PCV (16-025) will allow you to raise your rev limit but still needs manual set-up using a PC to adjust air/fuel ratios and requires the addition of the Auto Tune option to monitor air/fuel ratio.
