    I have added cobra dragster exhaust to my bike and getting ready add the FI2000R ol to my bike as soon as it comes in. I am also running the mod intake with K&N filter.. I was wondering if anyone can give me a general idea of what settings to start with. thanks in advance .

    Before making any changes you need to take it out for a ride and see how it feels. 15-20 miles not just down the highway quick even the techs at cobra will tell you the same thing. Your manual will tell how to adjust the unit it really is pretty easy to do...its hard to tell ya what to do since every bike responds differently to mods. Its more or less experimentation and what feels good for you.

    1-3-1 I think was my starting point. but it will need to be tuned to your own specs like 13 said.

    Hey birddog.

    DITTO to what's already been stated by 13 and Cole. Added to that, I've had a bunch (too many) conversations with the techs at Cobra and they will state that the standard settings of 1-3-1 for the 1300 represent their recommendation for those with either a stock or aftermarket exhaust. Once you modify the air box to increase the air flowing into the engine, you'll most likely find a benefit from increasing 'slightly' the 2nd (yellow) and 3rd (red) pots, perhaps by 1/2 number each. This will begin to better match a more ideal air/fuel ratio for your engine. You also may find that the 3rd pot moved to 2 could produce even better results, 'IF' greater performance in the upper RPM range is desired. Whenever you make changes, just don't do it while your motor is running, rather have it turned off with the key also in the off position. Please keep us posted as to your findings. Thanks.

    Thanks for all your insite. I will let you know how things go when we are free of the snow and ice. This time of the year all we can do is install mods and then sit back say how good they look in the garage.

    I would suggest riding it a while without the fuel controller. I added cobra pipes and the air box mod (no kn filter) and rode the bike 9000 miles without a problem. Plenty of power, no popping, no backfiring, plugs were the right color and still got 50 mpg. The onboard ecm will handle a lot of adjustment without the fuel controller add on. You may find you don't need it. A couple of hundred extra bucks to spend on bling....ogie

    I did take the bike out for a quick ride ( when it's 10 deg out it's got to be quick) the only pop I had was when I let off at high rpm. This is a want more then need item. sad to say I almost have the bike the way I want in now.

    this is because you didn't add the k&n filter. if you had done this you would have needed the fuel manager. for example if you dont have an increase in air intake you will not have an increase in exhaust. so you can put all the pipes in the world on your bike and it wont change your air intake. they go hand in hand. and once you add all that air, you then need to add more fuel. that's when you need the fuel manager. I guess you could think of your bike like your body. food is fuel, oxygen is air, and we all know what exhaust is.... too much food (fuel) and your running FAT.... too much air and your running too (lean). but if you can mix your air to fuel just right you will have good farts.

    DITTO to what Cole said.

    No, one absolutely does not "need" a FMS due to it being a necessity after adding a new exhaust system and a new or modified air box, but the engine will run cooler, run more smoothly and smile much more often if it does have the FMS accompanying these mods versus not having it.

    Cole he did mod the airbox and added a K&N unless I can't read right; it is late and I am getting tired. Drove my pick-up to work to miss the possible rain. Possible turned to absolute downpour!

    If the intake is good and being held back by restrictive pipes it is possible to need FMS without intake mods but not too likely. My 1300 loved the airbox mod, pipes, and the FMS.

    I understand that he moded his airbox. But without the K&N filter, you can put all the holes you want and it wont help. Only so much air can flow through the POS stock air filter. Its good enough to get you by and get you down the road
    But once you go with a quality filter like K&N you will burn that paper filter and never look back
