I recently bought a 99 X1 Lightning with a 1250 big bore kit, vance and hines exhaust, the bike only has 10,370 miles gave 1400 bucks for it. previous owner claims to have bought it with number 1 cyclinder blown, hince the brand new big bore kit. But here is the kicker, bike will start and run with rough idle, but stalls out on rev above 2K. I downloaded ECMSPY, bought cable, and installed drivers. Will not connect what so ever to the ECM. Gives me "no connection to ecm" I really wanna save this old bike. Any help would be AWESOME!!!!! I read that there is a couple of different version of ecmspy, read where 1.12.27 was the one to have. I have the one off the ecmspy website. | ||

Sounds like a good buy! Not a computer guy, but did you set the stop/run switch to run when trying to use ECMSpy? Not that I or anyone else here has ever done that . . . . Meanwhile, you can unplug the throttle position sensor and with a decent multimeter, check to see if the resistance change is smooth and even. Kind of hard to check the intake for leaks without the engine running; might do to replace them as routine maintainance/problem solving. A likely cause of a blown front cyl. I'm guessing the bike sat for a while, so considering the fuel injectors to be clogged might be wise. As well as bad fuel . . . . Check the fuel pressure and confirm the fuel pump is working correctly. Is the fuel filter flowing properly? Short(ish) version is that if the bike starts and runs, most everything is as it should be. The fact that it wont rev above 2K, with no CEL, would lead me to look at items listed above for starters. Hope this helps, Dave | ||

Followed all procedures on "how to" still no connection. I cleaned the injectors, replaced fuel filter, and changed plugs, today I'm gonna do a new fuel pump and regulator change. But I'm about 100% sure it's the TPS. I can give it a little shot of carb cleaner and it will smooth out. IF I could get ecmspy to connect I believe I could get it figured it. If all else fails I may convert to carb but I really don't want to, because the FI system when working correctly trumps the carb. THANKS for the reply Akbuell | ||

You are very welcome. Perhaps a PM to Froggy; he would be my go-to guy for computer issues. I have every confidence he could get you up and running. Some items have been addressed to check off the problem list. How did the plugs look? The carb cleaner thing is interesting. Makes me lean towards a fuel/air issue, which May be a TPS/TPS setting issue. If needed, go to I 75 and turn right. Turn left at Knoxville on I 40. About 25mi into North Carolina is Waynesville. About 3 1/2hrs one way per Google. Let me know . . . Dave  | ||

Or purpony he has good c1 knowledge also | ||

It almost sounds to me like it has the same issue it had before the 1250 conversion. When it runs, put a hand on each header pipe. Is only one getting warm? If so, the problem is in the cold cylinder. Wiggle-test. It could be as easy as a broken (or intermittently-broken) injector wire or loose injector plug. Start it, and while its running start grabbing wires and giving them a jiggle, one at a time. Check grounds. And, spray carb cleaner at the intake seals, NOT through the throttle body. That is the test for intake leaks. If it runs different when you spray the seals...there's your leak. | ||

Changed fuel pump and regulator, no change but the new pump sounds A LOT better than the old one. Both cylinders are getting fire, the old plugs where black on the ends like it was running rich, but when you get on the throttle its like it runs out of fuel. If I get the ecmspy to work I could reset TPS and might help it out. I'll keep tinkering around with it. I got plenty to do to it in the mean time the PO put a butt ugly paint job on it so I got nothing but time lol. Thanks guys for the replies. | ||

"I cleaned the injectors" How did you clean them? Did you have them cleaned professionally? | ||
| Akbuell |
Ratbuell and Hootowl reminded me of a bike I helped work on. Sort of the same symptoms, and we discovered that one cylinder was intermittent; it did not warm up as quickly and as much as the other. I had asked a time or two if the injectors were OK, and was told they were. After eliminating other possible problems, we swapped the injectors front for rear. The problem followed. Installed known good injectors, and the engine ran fine. Easy enough to try. Dave | ||

Visually confirm that the throttle butterfly is physically opening and closing with a twist of the throttle. The early design butterfly shaft has been known to snap, with the same indications. SteveH | ||
| Ponyboy89lx |
I visually inspected the butterfly its not broke, I read that they are fragile. As far as cleaning the injectors I removed soaked and then applied 12V to the flush, all and all they looked great to start with. Im thinking its a computer controlled issue the bike had a power commander II on it when PO bought it, he then rebuilt the bike and engine ran the same as now with or without the power commander, so he removed it but I do have it. Im gonna try to uninstall ecmspy and reinstall and try to get it to connect with the bike, I believe if I could get it to connect I could figure the problem out with your all's help. Thanks again guys for the help. | ||
| Ponyboy89lx |
ok I finally got ecmspy to connect and I assume my TPS is bad, im a continuous green bar on the screen I can twist the throttle and the green bar does not move at all. So I cant reset it if its not functioning. I will order one and try again. I am correct in assuming the green bar bar should move while I throttle the bike, right. I want to apologize for my computer skills. I read that a ford TPS for a older mustang is the same as whats on the bike, can anyone confirm. | ||

What operating system on computer? ECM Spy likes to run on low number com ports so when you connect cable look to see what com port was assigned to it. May have to go in and reset it under your device manager. And then when you open ECM Spy under options then communications you can tell it to auto-detect com port. Where did you get the cable? With black plugs it sounds like it is running way too rich. | ||

First make the ecm spy read the ecm, once done go to the main page and click the keys and see if then the number change when you twist the throttle, if it works I'd heat the engine up and do the reset then, also you can reset the afv. If it works, then take the bike for a spin and find where you can go on 5th gear at constant 3.000 revs for 5 minutes or so to make the ecm adjust. | ||

windows 7 OPS, com port 3, got the cable online it was made for specific for Buell. When I click keys it shows temp, volts, etc at the bottom where TPS green bar is ther is no response to twist of the throttle on the green bar. I looked at the TPS sensor looks like a butcher got ahold of it so im gonna replace it and try again. I did run some tests on ecmspy for injectors and coil and tach all seem to be working according to the test I could hear the coil clicking and the injectors pulsing and the tach went to 3k or so, im new to this computer tuning so thanks for patience with me. | ||
| Ponyboy89lx |
let me add I did read the DTC's, came up code 11 ( TPS short to ground). | ||
| Natexlh1000 |
Well there ya go. The computer give out a voltage to the TPS and it divides it depending upon the amount the throttle is applied. It's a potentiometer. Take a good look at those three wires. One will be rubbed through the insulation. | ||
| Pontlee77 |
Or may even been one broken, have seen that on an XB | ||
| Akbuell |
Most Excellent! Good to hear that ECMSpy is working, and the TPS is the likely suspect. And you are correct, the green bar should expand/contract as the throttle is opened and closed. BTW, is the AFV (adaptive fuel value) close to 100? A good indicator of how things are going with the engine. Dave | ||

I wont be able to look at any this week, I work out of town during the week, but I will post up this weekend whats going on with it. | ||
| Akbuell |
PM replied to. | ||
| Ponyboy89lx |
Got my TPS sensor in the mail gonna put it in this weekend and see what happens, Akbuell either I missed your PM or something but I could not find it. I was under the assumption that all PM's come through my email, correct me if im wrong but I didn't see any message, I apologize for not knowing the site very well yet also. | ||
| Akbuell |
My bad, most likely. Resent PM. | ||
| Ponyboy89lx |
put the new TPS sensor on and the old sled will rev up now, still rough but I never got to reset the sensor. Gonna do that later today. But just wanted to let everyone know we are headed in the right direction, and thanks for the help. Akbuell I still never got a email, that is how I view my private messages correct, if not someone please let me know how to read them. I had asked Akbuell what was the part# for exhaust gaskets, if anyone wants to chime in please do so. Again I apologize for my lack of computer skills. | ||
| Akbuell |
The email issue is just as likely a problem on my end. Anyway, the part number from my '01 X-1 parts book is 65324-83A. Given the number and suffix, I believe it will be available from any H-D dealer or independent shop. Some folks put them in the freezer overnight to ease installation. And it might do to practice with the old ones before trying the new ones. As to wrapping, I found it helpful to soak the wrap in water first. Keeps the dust down and makes the fabric a little stretchy while wrapping. Sure does stink for the first ride or so . . . Hope this helps, Dave | ||

Well I didn't get a chance to reset TPS today my wife had the laptop tied up all day doing homework, but I did get my header wrapped and swapped out the old turn signals for some led's. Also finally got my front brake lever switch figured out, it was not lighting up the tail light, turned out it was a loose connection under the tank. Making great progress on the old bike gonna try to do some bodywork and paint soon. | ||

TPS reset went wrong somewhere it wont even run at all now. I guess I do a little reading and see what I can figure out I did wrong. Here is what I did if anyone wants to instruct me on what I did wrong let me know. Connected to ecmspy turned idle screw out until TPS read zero, blipped the throttle a couple to make sure I was zeroed out. Click reset TPS waited for confirmation on screen. Then turned screw back up to 5.5 and was gonna fire it up to get the temp to normal operation temp, BUTTTTT it wouldn't stay running. Simply fire up run for about two to three seconds and then it would just die. | ||
| Reepicheep |
Try turning the idle screw out until you see, looking down the intake, that it is obviously not doing anything to the throttle plate anymore. Maybe the idle wasn't all the way out. Using the TPS to calibrate the TPS seems like it would work sometimes, but not others. | ||
| Phelan |
Honestly it sounds like the TPS is bad in general. I had this issue on an 03 XB9 I picked up a few weeks ago. I replaced the TPS and reset it and it ran fine afterwards. | ||
| Akbuell |
Have run into that before. Now, I set up the computer, ect and go to the 'instrument panel' on ECMSpy. Roll the TPS to zero degrees, then out another full turn or turn and a half. I then roll the throttle open and closed, gently, a couple of times. I can feel the throttle plate 'stick' on rolling open, letting me know the throttle is well and truly closed. Pull the throttle gently closed, and reset the TPS setting. Then throttle setting to 5.5 degrees, start and warm to temp, then idle to 1050 RPM. Hope this helps, Dave |
