Got my new Screamin Eagle air cleaner, that requires a "reflash" according to the catalog. I really did not get a detailed answer from the service department at the dealership on what was done. They say that the factory won't tell them what changes the reflash has on the ecm. I would just like to know what parameters were changed (if any). I paid $199.82 for this "upgrade".
The invoice says:

"Before
for "Part Number: 34245-09", Calibration ID: 32935-09A"
"After:
"Part Number: 34245-09, Calibration ID: 34462-09"
Description of New Calibration:
Street legal performance calibration, Use with ECM'S labeled: 34245-08, etc.etc.
Requires High-Flow or Heavy Breather air cleaner, stock or street performance exhaust..

Now, the question: I was led to believe that this "upgrade/reflash" would help the excessive heat issue on the '09 Ultra's and give a little better performance. I took an overnighter last weekend, and really did not notice any changes before spending $$$$ to solve a heat issue. I am wondering if anyone else has any experience in this area of "high heat" on the -09's (and 08's I'm told!). I guess I'll just leave the lowers off, the mid-frame deflectors on, and ride the bike in the winter!
On another note, the bike handles much better than my 95 EVO!!!!

Great to learn that your '09 rides better than your '95. That should make everyone at the moco really happy.

On your heat issue: Not many people have experienced "excessive heat" on the '09's, so I wonder what you actually mean? Adding an air filter which lets more air in would actually increase heat, unless you have made other changes, specifically on the exhaust side. Results of any ECM flash can only be compared using before/after dyno runs. Do you have those printed out? Or did your dealer simply install the different map in your ECM?

More questions than answers, right?

Ride safely,

The street legal calibration doesn't make the engine run richer when it's in closed loop mode; to do so would be in violation of emissions law and subject H-D to huge fines.  Where it does make a difference is under open loop operation, such as high rpm and large throttle openings.  If you want to richen the mixture in closed loop mode to reduce heat buildup, you will need a custom tune with a PC, SEST, or other tuning device, or at the very least a device to fool the O² sensor system into running richer than 14.7:1 (such as the Nightrider device).

Louis, the "excessive heat" issue is a two part issue.  The '09 model partially addressed the rider comfort portion by redesigning the exhaust and adding deflectors on some models, but the engine itself still runs very hot.  Richening the fuel mixture is still a good idea to improve the operation and longevity of the engine.

Thanks for the replies, I'll be looking to upgrade in the near future. I think the best bet at this time is to wait until someone has a complete exhaust system, as the stock headers has the cat, and by just replacing mufflers will probably NOT show much flow improvement due the the cat still in place!  I'll also have to wait until the aftermarket catches up with tuner (as from nightrider) that will work with the TBW system on the '09's. Most tuners (other than SEST) will not address the new ECM in the '09 baggers.
Again, thanks for the response.

That's correct, the temperature of the engine is the same. However most people with '07 and '08 had issues with the heat coming from the engine and exhaust, and as you rightfully say, these have been addressed by the frame and seat changes. I was wondering what Hogmike would refer to.

One of the reasons I got the '09 Ultra was the idea that since the factory changed the routing of the exhaust, the mid-frame deflectors, the rear cyl. deactivation at high engine temps. that the issues of the '08 cooking your right thigh at stop lights, were resolved? I'm not sure if my bike is typical, but, I have ridden other new bikes, and don't recall the excessive temps. Granted the other bikes were not Ultra's but in the same family.
Am I expecting this bike to be as cool running as my 113" FLHT? Maybe I'm trying to compare apples to oranges?
