    After having a dozen + conversations with the Cobra techs, it wasn't until within an hour ago when I heard it from Rick, the actual designer of the Cobra 2000 FMS units, that for our bikes only - our great Yammy....their CLOSED LOOP unit can be run either as a Closed or Open unit, depending upon whether, or not, the O2 Sensor remains connected. This does not apply to any other brand of bike.

    I was also told, due to the continuous providing of incorrect information, Cobra is considering a new training program in order to get everyone there "up to speed" with the technical aspects of their FMS and other products.

    While it burns me to be misinformed not once, not twice, not three times, but more than a dozen times by 3 different individuals with Cobra, I'm also grateful that THE REST OF THE STORY...the TRUTH...has now been told.

    Everyone enjoy their weekend.

    Cool news, Morgmaster!
    Well, now unhook your 02, and start experimenting with the dial, and give us the results!

    Neat how big (or small), companies like that dont' have a clue what kind of information is being piped out of their own stores. (happens more often then not), especially in the aftermarket car part stuff).....(don't ask me how I know).

    I heard Cobra is coming out with a new chrome housing for the FMS...just kidding.

    I second the thought to Morg - though in Cali if I get pulled over by a smart aleck cop I don't want to have to explain why I have an afetrmarket exhaust but no 02 sensor. I bet the ticket is $300 or more!

    Now when you say unhook the O2 sensor do you mean the one that connects directly onto your exhaust (muffler) or the one under the tank? Also, if it is the one on the muffler then how do you unhook it? I had the dealer install the fM and I've read on here how fragile they are so I don't want to break it by trying to turn when i need to pull or vice versa.

    It was said yesterday that, if one chooses to use their Closed Loop unit in an Open Loop format, they would need to go to the Cobra web site and download the Open unit's instructions and re-connect it accordingly. I've yet to even look at those instructions, but I will, although I'm also not interested in changing mine out to an Open system, either. I personally have no need, nor would I gain anything at this time by doing so.

    Enjoy the weekend.

    You don't remove to O2 Sensor, you just unplug it and plug the fi directly into the available plug (by-pass the O2). FWIW, you have the closed loop and all runs fine.......... let it be.

    The O2 is the connection at the bottom of the bike down by the exhaust.

    Disconnecting the O2(from the cobra's harness) making it an open loop... This is the information that Shane from SSCustoms gave me when I bought the FI2000 from him. I thought he was misinformed. I guess he knew his stuff. Sorry for doubting you Shane.

    I Disconnected my 2000CL a few days ago,just wasnt getting a good reaction from it no matter what i did.Saw Morgs post and decided to try it.Hooked just the injector plugs under the tank and disconnected the O2 plug under the cover.I took the 1st pot setting up to 1.25 and that smoothed the idle out the best i'v had it yet.More testing to come tommorrow.All i can say is I havent had much luck with this since I got it but its already looking better,dont know why its better OL but it looks like it is. Thx again Morg for the info.

    The main reason I purchased the Fi2000R CL was that I had problems with back firing, the bike already had Cobra Speedster Slashdowns installed when I got it from the dealer, they had only just installed them as it was their demo model. This is actually my second VStar 1300, as I crashed the first one into a car that decided to go through a give way sign. The first one had the standard exhaust, so I got at least some benefit from the crash, but didn't like the back firing, which was excessive and like canon fire! The dealer said there was little they could do about the back firing. Found out about the Fi2000 from this forum, thanks, it made a big difference, but the back firing never fully disappeared. Did the airbox mod next, which didn't change the back firing in either direction.
    Now I have unplugged the connection to the O2 Sensor, as per this latest post and YES the back firing is just about gone. BUT after the engine has warmed up, it won't idle for an extended time.
    I had set the #1 pod initially at 1.5, but when I stopped after having done about 10km of hilly riding, the engine stalled very soon after it started idling. I adjusted the #1 pod while the engine was idling and had to set it at 3 for the idling to last reasonably long enough to manage, by an occasional slight touch of the right hand. If I leave it idling without, it will eventually stall, maybe 1/2 minute max.
    Adjusting the #1 pod to a higher setting doesn't appear to make much difference to this idling problem.
    Other then that, I couldn't be more pleased having unplugged the O2 sensor connection, hardly any backfiring and a much smoother control at lower refs and deceleration.
    The idling is annoying though and if any of you have any suggestions then that would be greatly appreciated, thanks, Rob.

    Talk about a "shot in the dark," here goes: 1. Have you done anything at all that could have caused one of the fuel lines to become pinched, even slightly, which certainly could cause idling issues? 2. Initially advancing pot #1 by only a half number should not create a problem, but having to advance it to a setting of 3??? This usually results in a lot of fuel being pumped into your system at start-up and idle, also up to about 2,000 RPM, according to Cobra, after which they say pot #2 kicks in. If you need that much correction, I can't help but to "guess" that the backfiring is more than just your FMS settings, with one possibility being an exhaust leak due to having those aftermarket pipes. I realize they were installed by a dealer, but since others are running the CL unit with Cobras without backfiring issues, might the dealer be willing to check for a possible exhaust leak? They should. It happens so often when pipes are found as a culprit, even if it's only partially so.

    For fun, did you also ride your bike with the FMS set at 1 and, if so, did you notice backfiring then? Slight popping, okay...backfiring, not okay. At what RPMs was the backfiring taking place?

    I run with my O2 Sensor connected, therefore, I haven't experienced your idling problem, nor have I experience problems with backfiring, only just a little popping during decel. At what RPMs were you noticing the backfiring?

    In order, I would check for: fuel line being pinched / exhaust leak / properly adjusted FMS. Keep us all posted.

    Make it a great week.

    I did start off at setting 1, the back firing had then reduced, but not by as much as it has at the current setting. The back firing mainly happened at fast take off, at 'sudden' deceleration from high refs. and going down hill in low gear (where the gear does the majority of braking) Haven't got a tach so don't know the exact refs.
    Don't know about the fuel line pinched, will check, but thought that that would have caused the idling problem already when the O2 sensor was still connected?
    I will take the bike to the dealer to have it checked for gasket leaks, thanks for the advice!

    I'v ran my 2000cl as an open loop for a week now and i'm doing great,iv got good color on my plugs and it's running great.....the only thing that comes close to what your saying is after I start it up cold it idles fine for about 15-20 seconds then it starts to get get a little rough for about 10 seconds then picks right up and smooths right out,its like its looking for the 02 sensor for the 10 seconds and then the FI2000 takes over.After that it runs great and i'm really pleased with how its running.

    I tightened the exhaust nuts, they were loose!!, should have checked those first up, but I tended to trust the dealer for having installed the pipes properly (not anymore). It made a difference to the back firing, still a bit but can put up with it (might have to change the caskets). Checked the fuel lines, didn't find any pinching. With the O2 sensor out of the 'loop' it still doesn't want to idle for an extended period of time! Gone back to closed loop and it's working fine, will probably stay with that as I just don't know.
