06 Dyna Tuning Problems
I have a 06 Low Rider that I have put a1550 Stage 2 kit on. I have a sert and have downloaded the program 141nw002 which is an mt6 file made esspecially for my setup. It runs real strong compared to stock but it backfires and pops on decel. Ijust brought it to the dealer and am getting the 25 degree injectors put on. When the mechanic saw that I had red Screaming Eagle wires on the bike, he said that I needed the stock wires or Iwould get error codes. Is this true? I only bought the better wires because red looks better, but it really tics me off that the system would be so finnicky. I have spent a lot of time and money to get this bike to run like Ithink it should have in the first place. Why does there have to be sooo many sharp turns down the path of getting a 06 dyna to perform well? Should I wait awhile to do more? I feel like an experiment. I would greatly appreciate any input on this, and would also be glad to share my experience and info with anyone who might want it.
Thanx

RE: 06 Dyna Tuning Problems
Don't blame the bikes, blame the EPA! Carb'd bikes are no better. The last 3 new carb bikes I've bought were all but undrivable from the factory. You have to get intimate with Kehihn CVK's or Mikuni's these days end of story. You have to get around the needles with little or no taper (for emissions), and work around that with larger main jets to compensate. Another nightmare of a different kind and a compromised curve from top to bottom. Factory pro jet kits are pricey because they do this for you. No different with the EFI stuff. Gettin' familiar with EFI and closed loop systems is just another technology we all have to grasp since it 'aint going away and will get worse as time goes on. The techlusion TFI works fine. I set it up in 30 minutes and it eliminated all of the lean conditions and fixed my complaints. Now, I'm trying out the SERT more to understand what these newer systems are up to and how to fix them. Gotta learn it sooner or later, right? So in the end, we can collectively b!tch and moan or do something about it. I prefer the latter.
But there is some good news. HDMAPS.com has their 06 dyna stage one map for Screamin eagle exhaust ready to go and it should be posted tommorrow on their website. They might also have the 1550 so e-mail or call Matt and ask. Since they tech the Dephi systems, I'm confident their map is good. With so many parameters to tune, this would make a great base map jump off point for home tweeking. Most likely, it would work wonders with no editing at all. Problem solved.
Sorry for the rant ......but we can get this. Just stick with it!!

RE: 06 Dyna Tuning Problems
Hey , don't get me wrong. Ilove the EFI and the bike pulls real strong. It's just that the info pool out there is scary. The Harley tech line said that the constants table value for the new injectors did not change on the sert program. Later I find that the value does change from 3.91 to 4.89 grms./ sec. That's a fairly big change. Misinformation like this cannot only damage the bike. but it costs me uneccesary time and money.

RE: 06 Dyna Tuning Problems
I got the factory d/l for my 06, when I got the SE slip ons, and SE highflow a/c. Come to find out the d/l was ojly forthe A/C with stock exhaust??? That still makes no sense to me by the way......anyhow, I put the stock a/c back on and kept the slip ons. Seems to be running fine now. I am heading off to Iraq in July for 7 months. Maybe when I get back, there will be some progress on the whole set up. I will wait and see. For now though the biek is running well. Fl is right........just need some patience.

RE: 06 Dyna Tuning Problems
If you did a stage 2 you should have the bike dyno tuned. The 25 degree injectors are probably going to help but changing the wires can effect the ignition and efi system because it's a closed loop system and it is very precise. If you go buy a new Chevy and pull off the exhaust and put on non specific ignition parts you will end up with the same type of problems. Welcome to the high technology age of electronics. BTW, I just did a complete tune up on my 2002 Chevy Suburban......irridium plugs and new wires that's it and it will last 75-100,000 miles and took 45 minutes. Electronics are here to stay.......carbs are gone forever.

MY Dyna runs great completely stock and only pops when it below 45 degrees out and not very frequently. Get a Victory or a Boulevard that are water cooled and you wont have these issues.
