Okay. So here is what I am working with.

99 Buell X1.
-Prospect hill performance aircleaner
-Force Big Bore exhaust *No 02 sensor, 02 turned off on ECM Spy

At first it would not idle at all. Got it up to 160 degrees and did a tps reset and reset my AFV to 100%
Set to 5.1 Tps. After start up The bike idled right at 2,500rpm and stayed. I repeated the tps process with the same result. hung up at 2,500rpm then died. i turned the enrichener down to get a steady idle and took it for a quick ride.

After a quick test ride it would'nt idle when it was running. had to stay on the throttle. I noticed a major flat spot under 3,000rpm. As soon as I hit 3,000rpm it pulls beautifully and drives well.
I checked intake seals and exhaust leaks. none were found.

I opened ecm spy. and increased some values to make it idle. It now idles with tps at 2.7% on idle right at 1,000rpm. Starts up fine and idles, idles at a stop sign now. and throttle response is crisp...all that being said i still have that flat spot from 1200rpm-2800rpm Any guesses on why this is?

Any one else running a similar setup? I hear the force is tough to tune. this is so far where i am at on ecm spy. This is map modification 5. runs okay,idles, but it chugs from 1200rpm-2800rpm.
here are my front and rear maps

I'm not familiar with Force but your fuel maps, especially the rear, look leaner than mine with a V&H and Forcewinder set up.
All in all there is something not right with your bike. You shouldn't have to turn the O2 sensor off or keep the TP that low to maintain an idle and/or run the bike.

I have the Force race exhaust with stepped header as well and there is no way I can run it with the O2 sensor on. I would probably need some professional dyno tuning to get it to work. I'm running just off the race ECM map and it's running fine (I have the ForceWinder intake).

i run my 1999 x1, force exhaust and forcewinder intake with the race ECM...no problems.the problem i did have was i could not get the bike to idle unless the AFV was set to 135(!). got the fuel injectors cleaned and bench checked and fixed it right up, bike runs aewsome!!

There is'nt a 02 bung on my force exhaust. runs fine without it,as it should run right off the map.

X1_rider,Orngm2,and Kalali do you have a snap shot of your fuel maps for comparison?

AFV when warm goes a bit above 100. cold start enrichment works and idle is fine. It is idling at 2.7 at the tps. its been pouring rain here all week. going to try a few other map configurations and reset my tps again...

It would be nice to have a data base of Buell race maps with different setups. I guess im starting to build one trying to get this running right!

I'm running an unmodified race ECM map.
A data base of Buell race maps with different setups is a great idea, I've been looking for a map that will accommodate my setup for a few years now.

Serialk ...... if you have no 02 sensor surely the AFV will always stay where you have set it to as it has no way to measure to see if needs to either richen or weaken the mixture. So effectively you are relying on the base map being correct.

After researching a few hours in the archives I found the best solution...Thank you Snowbees Your Map is absolutely brilliant. My X1 now idles at 4.7/5.1 TPS. and runs like a completely different beast. smooth through all rpm ranges and gears. This map has brought my bike back to life. I applaud your tuning.
The difference between this and what mine was is night and day. still need to get this on a Dyno. but this is an excellent start

I might give that map a crack myself now.

Snowbees,thumbs up on your map from me too. My bike has never run so well. Cheers!
Is the map deliberately richer on the front cylinder?

Thanks Alfau, yes deliberately richer, i'm sure it was mentioned in a tuning guide somewhere due to heat difference .
Serialk, i would be interested to see the dyno results as i tuned the maps for my riding style which is never flat out.

I am also getting a steady 100% AFV for my sea level location , air temperature and pro exhaust/homemade air filter combo.
Air temp sensor located behind the headlight cowl.

I thought the rear was suppose to be richer? more fuel = richer and cooler? rear runs hotter.... My bike does not like this map bellow 3k rpm. doing some data logging and going to try and get this tuned sometime next week on a dyno.

No 02 sensor is making this a bit challenging.
It is running like a champ on the hiway. traffic and in town it sputters and chugs. No idle unless I bump up some values.

i had a few idle problems so used the race maps figures for tps 10 and 20. as for richer rear/front i cant remember but knowing me i got it the wrong way round !!

My afv dropped down to 89.5% using that map so I went back to my original maps.


Richer on the front is advised here.

I tried a few other maps with similar results before i decided to play with ecmspy and megalog to create my own maps.
Each of our bikes are set up differently.
The whole process became quite addictive getting the bike to run how i wanted with a stable 100% afv.

I had my X1 dyno tuned by JTSperformance using ECMspy. And it is a huge difference from how it was. I did have to mess with the the throttle idle adjustment and a tps reset when the bike got here from sea-level to 7000+ above here. But this bike runs so damn good it is stupid! And i will not share my map.....I paid damn good money for the tuning to give it away! Sorry! NO!!
4th gear roll on dyno. i have better numbers once i swapped out the the clutch ball ramp! It was slipping the clutch under WOT!

ECMspy is the only way to tune these bike correctly in my opinion!

Good point, Prey. You give your map away, you lose it.
