I don't understand all the noise about the download myself, put a TFI on it an know that you have enough fuel to not run lean. Makes more sense to me any way you look at it. Skip the crappy download as Terry said
Why would anybody want the download which is EPA mandated to be lean before you even get it installed.

I have a stage I upgrade on my '05 FXDI. Don't plan on any other mods this year at least. Is there a reason for me to buy a sert or can I just take it to TerryT's mechanic and have hime tune it with a shop sert and the dyno? In other words, do I have to buy the sert to have the soek done or can they just use a their own? TIA, Art
Well Terry you can include me as one who is running a "stone stock bike". I am new this past year to the HD family but have been riding for the last 32 years. Owning a Harley has been a real eye opener in all senses of the phrase. I never realized there was so much to owning one. So that I may be more enlightened, what is it that I would need to do, (in a nutshell) to improve my EG's overall running performance and what kind of $$ are we talking here, over and above the large chunk of change that I have already shelled out for my (what I thought was the top of the line) motorcycle?
There is nothing wrong with a stone stock bike. There just aren't that many of them out there. If you are happy with the performance then don't worry about it. If you want basic improvements then your best bet is a good set of SE Slipon pipes, the stage 1 air cleaner and the SERT. They can download (from the SERT) a basic map and modify it to your needs.
Cost
Pipes Guessing here but you can get an idea from your hd catalog $349.00 ?
Air Cleaner $139.00-149.00
SERT $459.00
2-3 hrs labor
Now alot of dealers are having 10-15% sales off and on this time of year. Check around. You can also get the SERT from Eastern Performance Cycles for approx 15% off with no tax to boot. Save some bucks where you can.
Art,
Same with you. If your bike is running good, leave it alone. Not everybody is a gearhead like me and some of the others here. We like to run fast and play like those idiots on their crotch rockets. You can ignore us if you want. But you fall into the same catagory as Soos. You have to buy the SERT. It registers to your VIN and can't be used on another bike. I know, another way to take your money but it is an excellent piece of equipment.
Anyone know what's needed to convert an 06 open loop system to the 06 dyna's closed loop system?
Take a look at page 36 of the January 2006 V-Twin magazine, Terry Components (www.terrycomp.com) makes a conversion kit for open-loop EFI.
If you go with it, please post feedback, I'd be interested in knowing what performance improvements it produces. I think the Rineharts I just ordered come with the bung for the O2 sensor, you'd have to either weld the bung that comes with the kit or get pipes like the Rineharts that already have the bung.

I don't undertand why people freaked about the closed loop EFI anyway. 02 sensors just help the ECM make corrections to keep the bike in tune. Even if they are narrow band and the corrections are small, I see this as a good thing. You get the right map in the ECM and the sensors just help it run better. Am I missing something?
No, you're not missing anything. I had planned on avoiding a new harley until that change was made and the bugs worked out. Closed loop is a marked technological improvement. What you want is a machine that will adjust itself for changing conditions. It really doesn't get any better than that.
New aftermarket EFI systems are equipped with a wide band O2 sensor. You enter in some basic engine information. Then go drive the car. That's all the tuning it needs. It makes it's own maps while you drive. I expect to see that for HD in another 4-5 years.
