Without any mods to intake, fuel or exhaust, will you see any improvements?
Not sure but I don't plan on having stock anything very long and I've had real good luck with this unit on my VTX.

I've always been happy with the Dyno Jet PC111 but if the manurfacturers start coming to market with the pipes and higher- flowing air cleaner options, I'm willing to save a few bucks on fuel mgt. I like the looks of the Rinehart 2into1 megaphone type option for power potential that BUDS makes or maybe Cobra's power pro 2into1. I'm getting anxious to start getting serious on the bike i was certain I wouldn't have to make any changes on.

I've used both extensively, it wont be quite as precise as the PC3 on the dyno with the air/fuel curve but in real world use they stack up quite well.
I'm just counting the days till I can yank that stock exhaust and the bracketry that goes with it off, and replace those stock aircleaners with some K&N cones.

Thanks for the info Lamonster. Like all of us I have been waiting for some aftermarket goodies and finally, gotta love Cobra. This unit should help with the lean factory tuning that most bikes come with and if all anyone is going to do it pipes and intake mods, this module should be awesome. When I get mine hooked up I will post any info, good or bad, as I am sure Lamonster will.

What is the difference between the dynojet & cobra units? Big difference in the costs. Do they do the same thing?

Chuck,

I have the Cobra. The main difference is, well two things. First the Cobra is about $160-180. The Dynojet Powercommander is around $250-270. Second, the Powercommander can be connected to a PC and custom downloads can be put on the unit and then plugged into the bike to remap the system. This unit is for pretty advanced people. The cobra is designed for the 109 and has three pots to adjust the fuel mixture, but you cannot download to it. For the basics like high flow air filters, pipes and the like, all you really need is the Cobra. If you want to drag race your bike and will require more options, the Powercommander might be for you. I have K&N filters and my baffles drilled out. These mods leaned out the already factory lean settings and a fi computer was sorely needed. hope that helps and good luck.

Hmmm.. I read both FI2000 & FI2000R, and didn't see any real difference.. It looks as though the FI2000 was updated to be as nice as the FI2000R. Someone please help me because I don't see any difference other than price.

ohio,

The Fi2000R also has a third adjustment for high range that functions much like a main jet on a carburetor. This third tuning option is for use with engines that have high flow air filters and or extensive modifications such as big-bore kits, higher compression or other performance increases where more fuel is required in order for the engine to run properly at full-throttle positions. The Fi2000R installs quickly and easily, usually in under 60 minutes.

The Fi2000 takes about 15-20 minutes to install and is really all you will need for the basic performance mods most of us will do. The Fi2000R is for serious performance upgrades for racing applications and the like. I have the Fi2000 and would reccomend it.

OK now i got a really stupid question what is the difference in the FI2000 and a power commander or do they do about the same? Or is one easier to use than the other one is? sorry for the question but i was in the process of getting the new intake and power commander for my Vulcan when i traded it off and the FI2000 i never heard of.

If I understand these plug and play units correctly, some can only add fuel, not remove from stock. Is this the case with a cobra unit? For this reason, I would be careful because you don't know what a given pipe needs until you put it on an EGA. With a full race pipe, the Buell is richer in some areas and lean in others, and requires full adustability that you can only get with a PC. I think units like the cobra really only smooth out the fuel curve in spots made lean by epa. Normally, full throttle carburetion is not lean. LaMonster is on the right track by dynoing the pipe first, and hopefully there will be an EGA availale at the time. As long as A/F is optimal, the best HP is being made.

The only difference between the FI-2000 & the FI-2000R is the wiring. :D one comes with the plugs & the cheaper one has to be spliced in :eek: I chose the one that has the plug ins! lol Mines should be here tomorrow :bigthumbsup: I hope this makes my FI light go away, since I now have a 2 into 1 exhaust :). I'll let ya all know how this Cobra box worked in a few days :)
