Viper 2 / Cobra FI2000

[NMUCat]

I could be mistaken but adding bigger fuel injectors will not solve anthing b/c the computer will still tell them to dump the same fuel as the stock injectors. The computer is the key.

As for the problem, i'd say get the fuel controller that was designed to work with the pipes you bought. Until you have a dyno and can see what is happening with the a/f mixture its just guess. Other option would be get a learning computer that can adjust with input from a O2 sensor.

?????? I have bluing. Nothing I can do about it now other than 'Blue Job' . I'm not going to pay to have these things re-chromed. The fuel controller was 'supposed' to be set for this combination according to Cobra. The pipes blued within 30 minutes! UGH!

Again, my question is "How hot do these pipes get?" If I had a max temp. I may be able to rectify the problem with a special coating the first 6-8" to get rid of that God awful coloring!

If I get working on it tomorrow I think I'll just screw those damn things all the way to the right and crank some smoke and look like a jet fighter on steroids!

If you really want to know, buy an infared heat gun. I think you can prolly get one cheap at harbor freight.

Lester, I appreciate that, but only need to use one time. Never needed one before and with all the experts on the Forum, I would assume someone would know.

By the gods, will this fuel controller nonsense never cease? I suppose I am fortunate that my bike, with the Cobra swepts and Fi2000r seems to be running fine from day one........or is it? Every time I read of someone having problems with this controller it makes me nervous, because I've never even looked behind the heat shield to see if the pipes were bluing. I just assumed that if the bike was running fine then there was no problem. It also makes me nervous that my pot settings are 1-2-0 while Richard's are 7-8-6. Should I bump mine up and see what happens? Like I said, my bike seems to run fine, but if I bump up the settings, will it run better? I hate to try to fix something when as far as I know it isn't broken. Are Richard's settings higher because he removed the baffles and I did not? Still seems like a huge jump in the settings when we have the same pipes, but the only difference is my baffles are still in. Does Painter have to set his pots higher because his pipes aren't as restricted as mine?

Sorry, Painter. I know none of this helps with your bluing problem. I just wanted to add my experience with this equipment, and maybe learn something myself.

I hear ya Steveo. I also have pipes and the FI2000. I had mine all professionally installed. The guys at the shop said they really liked the the way the bike was running at the 1-2-0 setting. So they left it at that. No change to my air intake yet, but they said that could change things. No blue pipes here.

I'm also on-board with missing our Jedi Master. Someone pissed him off, and now he's gone back to Degobah?

I agree Kirk / Steveo. What puzzles me is the obvious fact that the FI2000 is not significantly uniform in it's quality control. Or maybe it's the different bikes, conditions, atmosphereic pressures, high tide,low tide or just the dark of the moon that makes the settings pop all over the place. Frustrating, to say the least, to those few of us that ruin $700 worth of pipes because of a difference in one of the above.

I could not see inside the vipers to check ceramic coating but from what I could see it all looked good. The pipes were beautiful and had the sound and look I was wanting. Well, now I have to punt.

Many here have given great opinions and most all based on expertise and good reasoning. Still, there are things that just cannot be explained. If I had it to do over....I'd have ordered the Fuggin FC and may still.

Yeah, I guess I'll leave mine alone until I get a new air breather. No need to mess with it now since I'll more than likely, or definitely have to change settings with a new breather. That's why I want to get the new breather that Cobra has. Maybe they'll have recommended pot settings to compensate for the breather. Keep it all Cobra and I should do ok.

Gar who? Eh, he'll be back. You can't keep a good man down....not forever anyway. He won't be able to stay away.

Installed Cobra sweeps myself had no problems with the FI2000 at stock settings with stock intake....by the way Cobra says bluing is normal under the shield, this was in the install instructions.

This is good to hear. I like hearing something positive for a change. Also good to know about the bluing. Was getting tired of hearing that bluing is a sign that it's running too hot and the engine will explode, instantly killing everyone around it. (Sorry. Don't want to offend anyone. Just like being a smartass to amuse myself.)
