Some of you have responded to my previous posts regarding my bikes problems and I want to thank you all. I have received lots of advice here on the forums and it is greatly appreciated. Unfortunately I'm still having issues.

To recap:
Had the 103 St II kit done on delivery. Dealer parts guy put the package together with V&H Twin Slash Slip Ons and recommended the Stage 1 download.

Right off the bat the bike had extreme heat issues. Even running a country road at 60 with no traffic was like sitting on an oven. Got caught in traffic a couple of times and within 5 minutes of stop and go movement the rear cylinder was shutting off and the bike was pinging like crazy. Took it to the dealer and the tech did a 10 minute test ride followed by a few minutes of idling in the shade. When they checked the temp on the bike it was over 400 degrees. Needless to say they agreed there was a problem. They reached out to Harley who after having them perform a list of diagnostics told them "the bike is within specs. Give him his bike and send him on his way". Unf@#ing believable! Thankfully the dealer disagreed with them and after a lot of wrangling back and forth they agreed to pop for the SESPT, labor and dyno to try and cool the bike down. I decided to get rid of the stock header also and went with a V&H 2 into 1 Pro Pipe.

All the parts came in and they began the tune. Should have realized something was wrong when it took them three days to get to a spot where they thought the bike was tuned. No lie. I was in there and saw them working on it with the dyno for three days. They finally called and said it was good to go. I picked it up and the first 15 miles or so were awesome. I got on a nice lonely highway headed home and started picking up the speed and the bike started to get quirky. Basically anytime it was under a load it would bog down like it was running extremely rich. When I stopped the smell of gas was almost overwhelming. It stalled several times when accelerating from a stop in 1st gear. Called them the dealer the minute I got home and they set me up to come in today at 2pm so they could tweak the tune. After three and a half hours the tech called me back into the service area and said he was giving up for the day. He said every time he would tweak the base map and run it on the dyno the bike would override his settings. If he tried to lean the bike up a bit the bike sensed the leanness and overcompensated by richening the mixture enough to stall it out. If he richened it the bike would go the opposite way and adjust to lean it out to the point of stalling. WTF!

They are thinking it could be three things:
1. The O2 sensors are toast and giving bad data. They are not certain of this since they said they should get an error code if the sensors are bad.
2. The base map is corrupt. The base map they loaded listed my configuration almost to a T.
3. Some other electrical issue that is affecting the bikes ability to interpret the data from the O2 sensors or even accept the tuned map.

They are going to continue working on it next week. I'm at a loss. Has anyone seen anything like this before? Any other ideas of what might be causing it? The dealer has been awesome in trying to make this right with me but it is getting very frustrating. I have had the bike since late May and it has spent more time in the shop than in my possession.

 

Wow !!!

No expert here, but this sounds like a conspiracy. Sounds like the Mo-Co has found a way to prevent tampering. Hmmm !!
I'd aproach it from that angle. Order a new ECM (They come blank) and have it flashed your way. If it's like the modules in the GM cars (same- Delphi) they are a one time program.

I'm sorry, no offense here, but I'm liking my carburetor more & more. Just the heat difference btwn my 00 carb model & my wife's 03 FI (w/Stage 1) is un-believable. Oil temp proves it (03 is 30-50 deg hotter on any given day)
The 09 Street Glide I demo'd (back at the end of 08) was like straddling a white dwarf star, and the rr/cyl kicking out and the pinging when it re-fired . . . please. That's a band-aid at best.
And for what it's worth , that SG did not ride a damn bit better than my Heritage (as far as rr/susp) Handling, yes it was better, more solid and better steering (& brakes) but yeah . . .
I'll stick with carburetors for awhile.

 

Stage 1 on 103???? it sounds like you nee more flexibility in your tune...I am def not and expert...reaally...layman...looks like the tune they are doing is either too much of 1 extreme to an other....

 

Maybe I mispoke here. They recommended and did the ECM download originally instead of installing a fuel management system like the PCV or SESPT. It ran very hot with the download so they dealer decided to install the tuner. The bike doesnt seem to be accepting or adhereing to the tuners mapping.

 

I'd have the bike returned to stock and see where you're at. From that point you'd be able to see how the bike is bone stock and have a clean sheet to work with. If the bike is still acting up you and it can't be controlled you can deal with the dealer/moco for a replacement.

 

Sounds like your engine temp sensor is bad...It will send the ecm a signal that the engine is cold and the ecm will reply be giving the engine more fuel...When this condition exists it won't show any codes...Might be worth checking.

 

I will run that by my tech. Makes sense. Thanks for the tip.

 

I was reading a post the other day by HDMD in Florida..he said that he is having trouble tuning bikes with some of the major company aftermarket pipes that are being made.

Google him and give him a call..he may be able to help you.

 

Absolutely true. Doc is a wise man when it comes to tuning. Some manufacturers are not paying attention and the o2 bungs are too long to place the sensor into the exhaust causing false readings. Another issue is the techs are reversing the wires on the o2 sensors themselves. I personally would be leaning towards the pipe being an issue. If the sensor is not in the exhaust stream even when tuning the bike you will be collecting garbage data. Three days on the dyno? I would also be questioning the techs ability.

 

Turned out to be a corrupt base map. Monday he started from scratch with a fresh base map and it tuned up easily. Runs like a bat out of hell now.

Thanks for all the replies.
