So I posted this in the "Troubleshooting" area but haven't gotten much help and I figure maybe this area will get more traffic....any help is appreciated.

Ok, my problems started a few weeks back. I fired up my bike, 2012 FLTRU, and it was idling kinda high but I didn't think much of it. Off I went to a poker run. I made it about 2 miles down the road when the bike goes into limp mode with engine light. I was able to putt into a parking lot to see what was going on. I didn't find much obvious. The bike ran but had virtually no throttle response. I was a few miles from a dealer so I limped it there which was no easy task with virtually no throttle I couldn't go over 15mph. Anyway, dealer says, bring it around back. I figured I'd "limp" it around back but when I fired it up it ran like a champ....too much of a champ though, the idle was at about 3000 RPM but I did have throttle again. Dealer gets to it and took off the tuner (fuel moto micro tuner) and thinks they have it licked but even without the tuner the bike did the same thing. Tuner goes back on, after more time the tech says the throttle control actuator was bad and replaced it but I had no throttle. Well the TCA work was covered under warranty but 3 years back, I put 12" ape hangers on so the throttle issue wouldn't be covered. Their theory was it had a worn wire.

So last night I tore down the bars and thoroughly looked at every wire....no problems and I now have full throttle but I am back to having a high idle. Now, I'm not saying they didn't do they work, but I never heard the bike run at normal idle after they did the warranty work, I was not home when they delivered the bike back to my house. So, here I sit, looking for help.

As it stands, I have throttle but high idle, no engine lights. At start up it's easily 2000RPM but has been up as high as 3000 RPM at startup. I have tried the reset of the throttle cycle with no luck. I don't know if there is a certain interval that should be used between the ons and offs but it hasn't worked for me. Any clarification would be awesome. I have disconnected the battery for 5 minutes as was suggested somewhere else but that didn't help. I'm thinking complete reset of the ECM? Is that possible and would that affect my tuner? Oh, and I have put dielectric grease at the connector of the TCA and the purge tube on the throttle body is good, just a couple things I came across while researching solutions.

Any help is appreciated.

Have you checked your intake and exhaust for leaks ?

You have to reset your throttle by wire. I believe you turn the key on, do not start, twist the throttle to wide open and then to close. That should reset it. I don't have my manual in front of me, so look it up for sure.

I appreciate the responses. I have not checked the intake for leaks, will do right now. I can only assume the dealer did diagnostics put not sure, will find out.

as far as the TBW reset....there is a lot of conflicting accounts on how to do this. The suggestion given here by Smarty is a new one, not discounting it at all. I am absolutely going to try it but the others have said cycle the ignition 5 times, others say 3 or four times. Another says disconnect the battery for a set period of time. So what is this process?!?!

There are a couple things I just noticed when I was out in the garage. ONE: My tuner, Fuel Moto Micro Tuner, it has three settings and if I remember correctly when I bought it 3 years ago, Jamie (?) said setting one was stock, setting 2 is my "personal" map for my bike as described to them and three is open. If I'm right (doesn't happen often :eek:), I just noticed that the setting is changed to number one, or what would be stock. I'm almost positive it's always been on two, perhaps the dealer played around with it when they took it off or were trying to troubleshoot? Then, would they have changed the RPM switches? and I have no idea where they would have been. Next, did they plug the injector wires in the correct spot as per fuel moto directions? I'll be digging into this an look forward to any further input. Thanks again.

Update: Just did a volt meter test on the battery....11.7V and the manual says that 11.8= 0% charge. Getting new battery now. don't know if something is draining it or if it's time and that is causing any of my problems....thoughts?

Ok, here is how you reset the throttle by wire. I was a little off on my memory and looked it up.

Built into the system is a reset function. If the ignition is turned off with the throttle in a position other than 0 percent throttle, the system wants to use a higher rpm as the new idle speed the next time the engine is started. If you shut the bike off at 1,800 rpm, the next time you start the engine it will use approximately 1,400 as the new idle speed. To keep this from occurring you can reset the idle by turning on the ignition switch until the fuel pump cycles on and off, then turning off the ignition. Repeat this three times and the idle speed will be reset to normal, 1,000 rpm.

if you could find someone with a extra tbw sensor,you could take off the fairing and plug it in to rule out tbw sensor.if you have to get a new tbw.get the se version,it has no green connector and is plenty long enough to hook up with 12" bars.
