hot air temp ruff idling
i live in florida and finally got my bike back from the dealer. today was about 90 dg outside.
going through 5 o'clock rush hour traffic. at idle it starts to run a little rough. the hotter it got the worse the take off and a lose of power. you can rev it in netrual and hear the lose the rough idle. then to take off it was heavy on the gas and feathering the clutch. anybody have this issue. basically the hotter it got the worse it got. i am not covinced to due the "parade" download until i actually hear from sombody who has it and they like it.
as you can tell from my sig about my setup.
my local dealer had $25 dyno today and saturday. just a dyno no tuning. 68hp, 74 tq. does this sound right? to me it sounds low. i made a comment that i thought the 96tc is higher. they said that is the at the motor. this is on the wheel. anyhow they also said it is running rich.
looking to get a hold of v h to change that

RE: hot air temp ruff idling
I got the "heat mng download" last week. i think it helps and dealer said everyone so far has liked it. also went with pure synthetic oiland hd prem oil cooler. took off lowers for the summer too.
The dealer told me not to blip the throttle at idle in traffic and just let download do its thing. So far only just bairly notice a little 'bounce" at idlebetween .9 to 1 and seems to be cooler. If thats the only down side to download then might as well get it. its free the first time and free to remove the first time.

RE: hot air temp ruff idling
You need to understand that the IAT (Intake Air Temp) is part of the engine management system, and when the IAT senses temps of 125 or higher, the injectors are still firing the "Normal" amount of fuel, but the Intake Air is super heated and very thin of oxygen.....
Example, when I have a bike in the shop idling, I have to keep the IAT below 125, or the bike will start to run like crap at 175.... Superheated air is terrible for the intake, so I have to have a fan circulating air over the motor and into the AC unit, to promote a good motor operation....
The Air Temp was 90, your motor was above 280, and no air movement over the fins, or down the intake tract.... How hot was the pavement????? Radiant heat is a bear....

I haven't had the problem you're describing, even though our weather in S. LA is at summer levels already. I don't have the EMDL.
A setup like mine ('07 SG, Rush 1.75, K&N, PCIII) dynoed at 75 HP and 87 TQ, with TQ staying above 80 from 2k-5k. I am using this same PCIII map on my bike. There's no reason you shouldn't be around this level with a good tune.

RE: hot air temp ruff idling
hmmm..
This is my second summer of Phoenix riding. I've never had the heat management kick in. 90 is considered cool here in the summer.
I don't know if it being dry helps or not.
107 on the way home today.
Very glad of my cool vest and mesh jacket.
Whoops! I don't have it in my sig anyomre.
Stage 1 and SE pipes.

RE: hot air temp ruff idling
Same here, I live in Phoenix too and have never had the heat management kick in either, and this is my second summer with my bike. I've even sat at stop lights for 3 or 4 minutes waiting for the left turn signal in the 105° to 110°temperature range.

RE: hot air temp ruff idling
i would to here from more people who have this download to get more opinions on it.
what shovelhead bob says makes complete sense about the outside air.
i was wondering if having the basic slip ons is casuing me to loose some hp. have you ever looked down the tube of one? its basically a straight through shot. my neighbor has a set of ovals that he is going to let me use. do you think that will help with the hp?. after i change to the ovals i need to readjust the fuel pack. i wonder if this will take the richness out.

I doubt that your current mufflers are hoding you back that much, but your numbers are quite low. My 07 with PC111 a/c and ovals is 76/88.
From what I've seen that's about average. I think you just need a good dyno tune.
