Howdy Folks,
As the snow starts to melt in my valley and I start thinking(well, I think about riding all the time) about pulling the bike out, I'm in the process of doing the mounting some of the goodies I purchased over the Winter.
Question is:
I've got the S&S Tear Drop Air intake and am about to order up the Cobra Swepts (as soon as our dollar matches yours

), do I need to get a Fuel Controller as well????
I remember back last year in the spring when some of you boys were starting your intake/exhaust mods and you were just disconnecting the battery to allow the stock computer do it's thing. Can I get away with this?
Do I gotta get a Controller?
Thanks and a good Canadian Beer for the best answer!

Sent from yours truly, UPS to the Southern 48 or Canadian Mail the island for Senor.
Cheers
Johann

Yes.

There are plenty of posts on the subject, but I will take a stab at summing it all up.

Internal combustion engines are basically an air pump. By opening up the intake and exhaust side, you are allowing more air in and out. The fuel injection system works in closed loop. It doesn't get feedback from an oxygen sensor to adjust air/fuel ratios. It only injects a certain amount of fuel based on the stock pipes/intake. You will be moving more air with the stock amount of fuel. So, your bike will run leaner creating more heat for the engine and exhaust pipes. To compensate for this, a fuel controller is placed inline with the injectors to give it more fuel. I'm no expert, so take this info with a grain of salt eh?

Thanks Eh!
I have read a far bit, so now it's a bit clearer- I'll order a controller up too!
If you're comfy with sending me an address on my email [email protected] I get a beer on the mail plane as soon as I get out of camp.

Oh great; cold beer cans all covered with bearshit and moosehair and beaversnot and what have you; all the stuff them Candadidians take for granted

Jk John

- and yeah, you absolutely need the controller - run a search on fuel controllers first though, then hunker down for a LOT of reading - this subject been debated to death here but you might save yourself from a lot of headaches by the time all yer reading is done. Good luck.

P.S. Almost forgot to mention, since you're going with the S&S air cleaner and Cobra pipes, you might want to consider the Power Commander 5 as your fuel controller; I'm not recommending over any others, but just saying that since S&S has professionally dyno'ed the fury with their air intake and with cobra pipes both baffled and unbaffled, as well as with fuggin's pipes and maybe others (not sure) that might save you some headaches on tuning the thing. Like I say, read the threads on this; the guys here have tried all the fuel controllers with wildly varying results and all the headaches posted for all to read ... S&S has made the PC5 dyno maps available free to anyone who wants them - they'll email them to you for the asking or I or a number of other guys here can post them or email them to you if you need.

Here is the copy of the inquiry I made to Cobra about the high settings.

If your bike runs well, pulls nice and cruises nice you have nothing to worry about. Go ride and enjoy your bike. Thanks for asking Cobra, ride safe.

I have the cobra swept pipes and Fi2000 for my Honda Fury. I have removed the baffles from the pipes and still have the stock air intake. My dealer installed the pipes and controller. They had my pods set to 7-8-6. It seemed sluggish so they bumped everything up one notch to 8-9-7. The bike runs fine and they say this high of a setting will do no damage. I have concern for plugs and washing out the piston. Can you give me your opinion?

Rich did you mean to post this here or in the VIPER2/COBRA Fi2000 thread?

John:
May I suggest getting a controller from Fuggin Fabrication.
Given your remote-ness, you may be wanting simplicity.
If you spend sometime searching the fuel controller topic, you will see that there are several instances of FI2000 that Cobra recommends, requires having to dial it in quite a bit to get it right.

Fuggin Fabrication has dyno their controller with the S & S air filter and their pipes, which are very similar to the Cobra pipes. The key here is the air intake.

I have the S & S air cleaner with Samson pipes and this controller was plug and play out of the box.
I only made one adjustment, other than that it's been purring ever since. (Simple to do also)

My opinion on fuel controllers is more about the air intake and not so much about the pipes.
While people get all consumed on which pipes they have, the main change requiring a fuel controller in the increase of air. The S & S introduces a lot of air.

My suggestion, take it as you will.

Thanks Tony,
Honestly, All this reading is hurting my head(I like lookin at pics) and your email is simple. You're right my remoteness makes it so I just wanna ride and not do alot with any of my toys. My nearest dealer is over 7 hrs away. I may just go with the Fuggin Unit, and I may ask the S&S boys to see what they think.
Looks like I may owe you a beer too!
Cheers
