Ran about 3 hundred miles yesterday (2 up) oil temp was around 245- 260, pinging like a .....tch. I swear it wanted to shut down at idle the pinging got so bad.

Frustrated as hell because of the heat this thing was throwing off...unreal.
Outside temp nearing the 98 degree mark.

I decided to go back to the dealer and get a different tuner for the bike, so I decided on the SERT, got a basic tune just enough to get me to the place I am going to Dyno it. Well I tell you she runs a lot cooler and  she really Screams through the gears.
The gas mileage took a plunge from 42 to around 35, I will assume it cooled of and stopped Pinging because of the fuel it's dumping??

Here's something I don't understand....My exhaust seemed to get a little softer.. Any ideas on why?

Very disappointed with the Fuel Pak and it's performance on this particular bike and set-up. JMO
The SERT seems to be a better match. Wondering what the Dyno will do to the bike??

Any Yeah's or Nay's out there with some input.

Thanks

Don't worry about HP. 

Have them shoot for around 13.2 / 13.6 to 1 air/fuel ratio throughout the power range from 2500 through 4500 RPMs.  If you install a 95 inch 48-state header pipe and a good flow-through muffler the bike will cool down significantly and be pushing around 108 tq and 90 hp.  Many of us have achieved this result with the minor mods I mentioned. 

You should also pull off your lowers if you already haven't yet.

Hey Dick,

Yesterday was pretty hot here in Williamsburg and that's not an excuse for what you experienced. It sure didn't help the rider comfort level.  I use Hampton Roads HD for my work.  I know they like the V&H Fuel Pac.  I'll assume you go there also. Many are still waiting for the ThunderMax fuel packs.  I didn't want to wait and thru the CVO Website here I saw lots of postive comments for the Power Commander V (PC-V) with Autotune.  It's about an $800 dollar investment.  HRHD installed the Klock Werks 4-inch exhaust, Stage 1 mod and the PC-V with Autotune.  Ran it good today up the parkway and down the interstate.  Ran good, cooler and sounded great. Sorry you're having the problems with the Fuel Pac, but I had the V&H Fuel Pac on my 2000 and 2005 Ultra's and wasn't very pleased with how it ran long distance.  This is my first experience with the PC-V with Autotune and so far (1 month) no issues.
Chad (HRHD) has the fuel map saved at HRHD if you go that route.

Ride safe and we'll see you on the road!

  My mind was in the gutter.

I'm guilty too!

I was gonna send this right off the bat!!!

Had same problem at Daytona Bike Week,
Bike actually shut down it got so hot.
I have done all that you have mentioned and one that you have not.
Pull Baffles and Cats off and installed 1 3/4 Fulsacs. I really beleave this is what really made the difference on the heat issue.
Cats are power robbers, and hold the flow back so much it creates all of that heat.
Mileage awefull, but can live with it.

 I have the SERT and mine has been dyno-tuned and still pings when the weather gets hot. Cool late-nite rides, or cold days, runs perfect. Dealer said that he could not tune the pinging out completely. Unfortunately, I have started to just learn to live with it. My cousin in Carolina has an '07 Ultra Classic with the 96 cube motor and says his has never pinged since he's had it, guess it's just a big inch motor thing, that's what we get for spending the extra dough, a engine that gets hot and detonates when you accelerate..

Remember there is lots of ethanol in the fuel nowadays, it is junk.

You should also pull off your lowers if you already haven't yet.

An Experimental Research Tech I know at the Development Center wanted to know what the lowers on his Ultra did to airflow and cooling. Did a before and after from a cold startup.... the cylinder head temps were actually 12 degrees cooler with the lowers on. An engineer confirmed that's because the lowers are shaped to put the cooling air where it cools the engine most effectively. Which explains the heat with the lowers on... that heat coming off the cooling fins has got to go somewhere. Fortunately, our friendly, considerate H-D engineers make sure it baths the rider in nice warm hot for those cold days.

Learning to live with pinging shouldn't be an option, IMO.

Took a trip west on a new, stock '07 Ultra in '06. Everything was great until somewhere around TX or NM. Started pinging rolling on starting up grades in 6th, downshifted to 5th. Over time it began pinging rolling on lightly in 6th OR 5th. Started paying attention to the effects of different gas and found I had less pinging using Sinclair than any other brand. I always use 93 octane back east, highest I found routinely west of TX was 91.

A guy at the party I was going to in CA writes for Hot Bike and had an '07 SEUC demo for the trip When he found out I was on an '07 the first thing out of his mouth was "does yours ping like crazy"? I said only out here in the land of crappy gas. On the return trip once I got east of NM the pinging stopped whether I was using 91 or 93 octane.

I've since swapped out the OEM ECM for a ThunderMax. When I experience very minor pinging only on the hottest of days I did a logged run and made note of the throttle position and RPMs where the pinging occured and took a few degrees out of the timing in those ranges. Not a ping since. I can't believe a dealer versed in tuning a SERT wouldn't try to take a few degrees of advance out of the timing in the areas where pinging is most prevelant. I assume the timing is adjustable on a SERT? I have no experience with that tuner....

I always thought this, nice to know I wasn't just blowing hot air out the brain w/those thoughts.

yes......very interesting.  Now, I just wonder what the little heat deflectors that you add over the rear cylinder do to hold heat around the motor thus raising the rear cyl. temps?  Better for the riders comfort at the expense of the motor     spyder

Since they're puttin' 'em the '09 Ultras now I suspect the MoCo subscribes to the theory that you can get a gnu motah, you can't get new thighs.     Makes about as much sense as some of the other stuff they come up with.

I picked up a pair of the Kuryakyn deflectors but haven't stuck 'em on. For heat solutions I went to duals, fattened it up with a T-Max, tried always riding in a crosswind and everything else I could think of. Reports indicated the OEM H-D deflectors worked better but are a royal PITA to install. My solution was to get them pre-installed on a '10 due on the first truck. Pricey solution, eh?     Wish I woulda neve ridden the '09s. Ruined me....

Nah, they are a breeze to install......as long as you have the fingers of a 2yr old.....removing mine, I found it easier to just pull real hard til they snapped, then took the bolts out when I had the rear jug apart. 

As for the heat and pinging.....it's not just the 110" doin it, my 103" does also.  Got pretty hot yesterday after about 80 miles and I could start hearing it, have the TTS so I dropped the timing a couple degrees on the upper end of the Spark Temp Correction Table last night, will see how it does this afternoon.
