Fellow riders,
I am looking for assistance with a PCIII issue on my Electra Glide Ultra. The bike is a 2006 that was taken to the 103 build early in its life, 253 cams, screaming eagle race only slip ons, and of course the HD download. By 103 build, I am speaking of the 2006 screaming eagle part number 29877-06, which at the time was $2995.95. It took the bike to 1690cc.
At any rate, this particular bike belonged to my brother, who sadly passed away at 44 years old from cancer. After he passed, I bought it from his estate in hopes of getting it back together, he had laid it down and there was some damage, but I have since restored it to original after much effort doing the work myself, so.....its an important labor for me.
I have had engine issues with the bike in that there is a sputtering(?) at 1500 to 2000 rpm. I checked with the dealership and the proper download was applied to the ecm, but there was no changed in this rpm area. I installed a PCIII from FuelMoto, which has helped the bike in many respects, however the issue still persists at 1500 to 2000 rpm. I have spoken to FuelMoto over time and they have sent me maps for the bike, but none seem to work....they seem to run "fat" on this bike, one actually stalling the bike out. I next contacted dynojet and asked for assistance as there is no map on their website that works for my particular application, believe me, I tried several and dynojet sent me 2, both of which still had the issue. I did go into the closest map and increase timing in that area and it seemed to help a tiny amount, but its still there.
The bike has been in the dealership.......who found nothing wrong but did replace injectors for me just in case. The dealership is where the bike was purchased and the same that did the build.
Clearly, I feel that it is a mapping issue and I have contacted an individual that has strong dyno experience in my area, but it looks to be at least a month before that can work out.
In the mean time, I wanted to ask if anyone else out there had experienced this issue on this particular build, and if you ever resolved it. Yeah, its a bike.......but to me its much more so I would love to resolve this.
Anything outside the 1500 to 2000 rpm range runs great, and at the present Im getting 43mpg so that seems fine. Oil temps at operating temp are running at 200 to 230 with outside temps above 90 degrees, so that seems good.
So.......any help is much appreciated, thanks for reading my long post.

 

I encountered a problem once where my bike had 'screamin eagle injectors' and no canned map would work because the SE injectors flow more at the same pulse rate. Every canned map was way rich. Oddly, it took several 'experts' to figure this out...

 

Thank you for the reply. So......dynotune was the way you cured it? It just frustrates me that Im not able to get the right combination in that range

 

Yes, custom map on a dyno. No matter what's causing it, that's the best way to nail it down and fix it. Best of luck with such an honorable project!

 

Thank you very much. I have a problem getting in for the dyno as he is booked solid and the dealership "prefers" to only use the race tuner......so......just hoping someone might chime in and I can resolve it here

 

Find an authorized dynojet tuning center near you. Someone on this forum can probably recommend one...

 

Since you are loading maps, you obviously are hooking it up to a pc and have some of the fundamentals of the PC3.

save the map that works best and then just start tweaking the area that you are having issues with 1500-2200 rpms. It's going to be the 2-5-10-20% throttle positionings at that low of rpms. Larger numbers increase fuel....smaller numbers decrease fuel. In that range you are talking about is taking off from a stop, rolling on the throttle. I would have to guess you are probably needing a little more fuel in those blocks. You have to think sorta like that you don't have a accelerator pump like a carb and need to squirt a little extra fuel in when stepping on the accelerator.

If adjusting one way makes it worse go the other. If you get totally out of whack load the map and start over. hope this gets you buy untill you can find someone to tune it. and if you have to go to a guy that tunes jap bikes they all like to use a power commander

Hope this helps I've done all my own tuning on my own bike, but I also had a air/fuel ratio meter data logger.

 

Thank you for the reply. I agree that its probably minor adjustments in that range as everything else seems good including mileage and oil temps. I think I may go at it at intervals of 5% up or down. Right now its the closest I have been able to get it and Im at -1 in that area on fuel and +2 on timing, of course that is on top of the HD download.......so I have no idea what those settings are. I started with much more fuel and less timing and that didnt work so I basically started reversing the two. I also had the map promoted to advanced mode which allows me to work with each cylinder. I guess that best part of it.....if there is one, is that I can actually sit there and rev to those levels and "feel" it vibrate and hear it sputtering, so it is not like I actually have to get it out on the highway and work back and forth that way.
Again, thanks for the reply,

 

I really didn't have to mess with the timing much until I got to around 2500 rpms. Try setting them to 0 - 2500 and under and let the ecm do the work in that range.

I also have the stage 1 download and am running a PCV (5) I have a lot more motor and the timing is fine in the lower rpms. 103" 11:1 .660 lift cams.
I'm not sure if the pc3 allows rpms to go to 6200 or not, if it does turn it off as it will conflict with the stage 1 download.

You may want to ask jamie at fuel moto what the closed throttle voltage and open throttle voltage should be set at. I can't remember 4.785 i think open/full throttle? .856 closed/idle? I can't remember although. These are important.

Take notes. and if you have to start all over from the saved map

 

Thanks sir, I went to a zero map and tried it in that area, same results. I also followed that procedure on the open and closed throttle positions....
I have read that the screaming eagle 253 cam had an odd configuration to it, but that is what my brother had installed and I would rather get it right than to change it.....I suppose my desire to keep "his" bike alive, so to speak.
I know Jamie is on here a lot, he may check the thread and reply if he has anything to suggest. I did get the PCIII from him and one of his staff sent me a couple of maps so they have been supportive.
I have replaced plugs, plug wires, throttle position sensor, battery, checked all wiring including under the tank when the new injectors were put in(the 25 degree injectors).....
Its odd that the bike runs so well the remainder of the time with the exception of 1500 to 2000 rpm, which keeps bringing me back to the map.
Its selfish on my part, but the anniversary of our last ride is in a couple of weeks and I had wanted to take the bike out and retrace that trip since I have it all back together, but the dynotune cant be done before then.
I appreciate your replies and very valid suggestions sir!
