I have a 2000 x1 stock with only a slip on. less than 1000 miles. throttle response has been terrible from day 1, and cruising at speeds under 40 is miserable, surging. The bike is just not happy unless its at 3500 rpm looking at the new pcll's on ebay, I do NOT have the exhaust sensor that many people reference, Will this pcll help by itself, or must I have the 4 wire sensor as well | ||

If you just have a slip on muffler, I'd save yourself the trouble of dealing with a Power Commander all together and just get a race ECM. They are plug and play and very simple to install. You probably need to put on a K&N filter in the airbox also & get a TPS reset at the dealer. With just a slip on you are probably running lean. You'll need the K&N because once you get the new ECM or PC set up you will get better flow with more air coming in to match the more air you are flowing out with the slip on. With the slip on you probably need the race ECM or a PC to regulate the fuel since you are likely flowing more air now than the stock muffler. The PC and the race ECM will both work, but the race ECM is just easier to install and doesn't require as much dialing in on an only slightly modified set-up. Good luck. Delta | ||

Tj: to answer your question pc2 fools the ecm by altering the signals pc3 alters the ecm output to the injectors "in theroy" you can add or remove fuel. the sensor prolly does not help that much as it is a "heated sensor", also your bike is 5 years old you can have Inlet air leak, a number of our long timers say about 2 to 3 years then change them dirty filter fuel these bikes are hard on plugs too crapped out Engine temp crapped out iat ( intake air temp ) bad gas the race ECM is the best if you dont want to have to further alter things, I have the pc 3, it was fun to add in and is now some thing else to break, see my profile for mods, HP is posted in the KV in the force winder section. | ||

Neither the PCII(which is less than substandard anyway) nor the PCIII will help you with your problem. Below 3k the system isn't adjustable with the Dynojet products. Technoresearch makes Direct link which would probably be more viable for you. The downside of that is there aren't a lot of techs that can use it. Short of taking your FI sytem off and switching to petcock and carb(which can be pricey), the race ecm may be a consolation solution for you. | ||

I should have said I bought this bike NEW almost a year ago and it only has 1000 miles on it. I'm not looking for more hp just cleaner/smoother operation. i did not know that pcll and lll's cannot adjust under 3000 rpm's If I was understanding that post correctly it seems race ecm are hard to find. | ||

Tj: check with American Sport Bike and Daves both carry the race ecm about 220$ also your bike is 5 years old you can have Inlet air leak, a number of our long timers say about 2 to 3 years then change them its not about the milage it relates to time and heat cycles. Pammy what about direct link, is this the software that allows us to tweek the maps? (Message edited by oldog on April 06, 2006) | ||

I have an X1 myself, so I know what problems you are experiencing. HP wasn't in my mind for you.  Direct link is the same system on which Al at American Sport Bike did the most excellent report. | ||

I concur with Pammy. An aftermarket muffler with a K&N air filter and my X1 was surging badly. Added a Techlusion DFO and still had the problem. Added the race ecm and that cured the problem. Fortunately, all the work was done with the assistance of a dyno. Of interest, I kept the DFO to take out the lean spots that the modifications caused and it is still working to this day. | ||

I too concur that the race ECM is the way to go. A dyno tune is not necessary, you can't remap the race ECM anyway, it does what it does. You will need a TPS reset and this can be a challenge as many harley shops don't seem to know Buell's. That said, my X1 with the K&N, ECM, etc, has very crisp throttle response. To add any more throttle response would make my bike less ridable, the front wheel really needs to stay on the ground. I can say there is no miserable place in the range of my throttle, not a flat spot anywhere in the response, X1's are simply a joy to ride. Goose the throttle going uphill in top gear at 60mph and pull your arms out of their sockets. There is no surging and no lag....It's great! | ||

Pammy: I wondered if that was it, to bad about the 1 dongle to 1 ecm, | ||

DirectLink is now suposedly working with the tube frame ECMs. I say "supposedly" because we have not mapped one yet. But I've been speaking with a couple shops that were, and were having great difficulty because the break points in the tables are different with a Tuber ECM than they are with an XB. But that has been fixed, and it is supposed to be working fine. Al | ||
| Whodom |
Al, Are you planning to offer DirectLink re-mapped ECM's for the tubers eventually? | ||
| Pammy |
Al...Ol' Francois(I can never remember his real name) said they work well with the older Buells. Of course he is trying to sell them to me. I haven't tried it either, though. Oldog, "I wondered if that was it, to bad about the 1 dongle to 1 ecm," I am sure I should have a clue....but....not  | ||

Al / Pammy thanks for the info.. |
