Doug is no longer with Fuggin Fab bro. I'd love to look at mine and share my settings but I no longer have a Fury to plug it into.

RY, Doug closed for 1 day, BUT he is reopening in different location! Wait couple of weeks. You can order through his dealers.
Thanks Mental, appreciate the info...RY, Doug closed for 1 day, BUT he is reopening in different location! Wait couple of weeks. You can order through his dealers.
I can tell you from personal experience that Mode 4 controls the amount of backfire that is being put out by the bike. I went from 1 on mode 4 to 2, then 3, then 4, to my current position of 3.5. There is a huge difference in the amount of backfire that my bike produces now.
From my conversation with Doug a few weeks ago, mode 4 is a new feature in a lot of the new FC's they have put out, mode 4 may have did something different before, but mode 4 is now specifically in there to help control backfire on decel. Don't know if they didn't change the literature to express this, but that is my understanding of what mode 4 actually does.
This is at least my conclusion as I am getting excellent results from moving this mode around. My suggestion would be to take the time to sit down, read the manual like you were studying for a test and then come to the conclusion of where you are going to move your mode's to, based on an educated guess, not a random guess. Again, don't know if mode 4's literature is correct or not, per the conversation with Doug.
From e-mail:
James,
The Fuggin EFI fuel Controller you have has a decel mode, which is mode 4. We put this mode in for just the problem you are having.
Now because I have not tested our our controller for your set-up, you may need to make a number of adjustments before you get the right setting.
To make an adjustment to mode 4 (ref attached picture) with the bike running, you need to press the mode button 4 times, until you see the Green & Blue lights on as shown in the picture. Once you see the Green & Blue Lights, press the + one time. You should 2 Green lights & 1 blue. That is a .5 adjustment. (Note; You must press the + button with-in 30 sec. of going into mode 4 or it will close the mode)
Now you are going to need to ride the bike each time you make a step in the adjustment. Each time you press the + button it is .5 step, so if you push 2 times it's one step.
Your really going to need to continue to step and ride step ride until the popping is reduced.
If you have any questions or if your are have problems, let me know.

And this is also the reason I bought it. In addition, I wanted something that was going to work with the Viper 2s, I didn't like any other pipes that I saw.
BTW, The early models of the fuggin controller did NOT have the decel chip or was not programmed correctly. (This is per Doug) He would fix that for you if you had problems with pop on decel. He just asked that you send it back to him and he would reprogram. Now what I'm about to say is total speculation, but reading the controller documentation and the RPM range defined for mode 4, I wonder if the adjustment Doug told me about was to redefine mode 4 to an appropriate RPM range for the Fury.
I have not posted my settings because I'm starting from square one. Predator also has this fuel controller and the default controller settings are the settings from his bike after it was dyno'd. His bike also is very similar to mine, so I figured if it worked for him, it will work for me.
Search this forum for pair valve removal or desmog. It seems like there are a lot of people that think removing the pair valves would make a significant difference. I bought the service manual for the fury and read up on it last night. It seems easy enough to remove and thanks to a posting by Gar, I think I understand it well enough to give it a shot. This doesn't mean Gar suggested doing this, as a matter of fact he didn't endorse either doing it or not. Other people that I respect as being more authoritative on these matters are Clueless and BarFury both of which have chimed in on this being nothing more than EPA requirements and does nothing for performance. As a matter of fact, I think clueless has removed the secondary air system all together.

I have also read about dsmogging on other forums and talked to some bike mechanics and they also have informed me that a lot of people remove the pair check valves when they modify the intake and exhaust.
All this talking got my buddy to try it on his bike (not a VTX). He didn't have a lot of backfire or gurgling, but it was there. After he desmogged, the bike doesn't snap, crackle or pop.
At lunch today I figured I'd try blocking the fresh air vacuum hose that runs to the pair valve solenoid. I then went out to ride.
No backfire, no popping. None. I tried to ride like a jackass, heavy on the throttle keeping a higher RPM. Normally that's where I have problems, yet I still had no popping on decel.
The true test is going to be taking it out on the expressway, once it passes that test I'm going to remove the secondary air system all together.
That's all I have to say about that.
Awesome, glad you chimed in! I have been thinking about taking out my pair valve as well for awhile, but my mechanic didn't advise it because of possible warranty issues. So, I never did (least for now) and I am wishing that I would have now. Appreciate all your honesty about your testing, pretty sure it will help somebody out, including me once I get around to removing the valve.And this is also the reason I bought it. In addition, I wanted something that was going to work with the Viper 2s, I didn't like any other pipes that I saw.

Good info you provided.
I found that I can create poping on decel by not allowing the throttle to return fully and holding it partially..
I can get it popping pretty good.
I too am considering blocking the fresh air vacuum hose that runs to the pair valve solenoid.
From your test at lunch it sounds like it had a noticeable effect.
Keep us informed on the expressway ride.
Thanks
