and I'm having a real time with that thing. First, I'm having trouble getting the Cobra FI2000R mapped. But I think I might have that somewhat done. I finally set it at 120. But it still pops and backfires between shifts and during decel. I've taken the air breather out of her thinking she wasn't getting enough air. I've plugged up the hoses coming out of the rocker covers but not the ones in the air breather. Did'nt figure they mattered anyway. And after I put her to bed, you can hear her moaning as she cools down. WTF, people?? I can't leave the air breather outta her, but I know she needs more air. Any suggestions on any of this?? She's an '09 Classic LT with the Cobra 2 into 1 pipes and an FI2000R.
Just outta curiosity, do you think the exhaust is sucking air at the crush gaskets? Also, I have my settings at 350 but I still have a small amount of popping. Even with everything stock, you have popping, but you just don't notice it because of the mufflers.
So you do not have an aftermarket air intake? If not i would take off the FI2000 and see how she does. Without after market pipes and intake there really isnt a need for a fuel programmer. It sounds like are you running really rich. i had pretty bad popping with my freedoms but once i plugged the ports on top of the engine most of it went away. You could pull a plug and see how they look to determine if your running lean or rich. Good luck and i hope you get it dialed in
Like silentghost said you should make sure the exhaust bolts are tight, the front right one is a pain in the ass to get torqued. Use a 1/4 inch drive extension with a knuckle, that makes it pretty easy

[QUOTE=jmorris;269583] And after I put her to bed, you can hear her moaning as she cools down. WTF, people??
Agree with Sarge on probably too rich.....
And the "Moaning" you are hearing is more than likely pressure built up in the gas tank, caused from the heat of the motor and being released through the relief valve in the gas cap.
Open the gas cap to release the pressure. Sound will stop until pressure rebuilds.
The fuel processor was on there when I bought her. I had set it all the way down to 000 to see if that would help, and it didn't, so started dialing in and taking her out to see how she ran. This was the best I could find, so just left her there. Wish I could afford a dyno tune, but that's not in the works yet. Any suggestions as to which air intake to look for?? Saw Baron's made one.
Don't think you need to spend the money on air kit, just put in K&N filter. Several mechanics have told me air kit really won't allow any more air than a K&N filter. Fi200r at 120 really sounds way to lean and would increase engine heat and increase chance of damage. I have Freedom Performance pipes and K&N filter and Fi200r set at 3-5-0..Still pops on decel. Learned how to handle throttle on decel to avoid loud pops. Spoke with a reputable dyno center where I plan to go and they felt it was still running to lean, dyno will tell and I'll report after it's done.
if you are talking about the KN for the stock box your mechanic is wrong. The OEM air box is sealed and most aftermarket intakes have an open filter. There is no way the stock one can introduce as much air into the engine as the barons or spike ones. Not trying to be rude just saying. Here is the Barons BAK , slimmer profile then the stock airbox and really lets the engine breath.
Think I might try the Baron's and see what happens. I might increase the fuel just a notch or 2.
Also, I have been looking for engine guards for her but don't want the big ole guards that stick out about a foot and a half. Found some for about 250. Anyone have any suggestions.
