Changed Baffle size need new map : V-Twin Forum: Harley Davidson Forums

King B · 10-10-2009, 05:40 PM

I recently installed a PC III with map M807-059

2005 Road King Classic
TC 88
Stock ECM
K&N RK-3909 AC
Wild Pig Slip-ons with 1.75 baffles

It ran well but I just changed to 2.0 in baffles.
It sounds good and runs OK but it's it's not as smooth and crisp in first gear or when rapping the thottle at idle. It runs fine at higher speeds/gears.
I don't see a map listed for this setup so I was wondering if anyone could suggest which one would be a better match.
Thanks for any info.

Give the attached map a try and let me know if it is any better for your setup.

Thanks much!
I will certainly do that.

Yes, it’s absolutely better. It was just a quick 15 mile run but a mix of back roads and freeway. The sun’s gone down and it’s getting cold out this way so the next ride will be longer.
I feel good power pretty much everywhere. The best it’s run.
I get a fair amount of blubbering on decel mostly at mid-low RPMS (I don’t have a tach), backing off in third gear at 30MPH.
I’m thinking that’s not bad though so I’m going with this.
I love how easy this is to do (for me anyway, you did the hard part).
Thank you, this is much appreciated!

Is the blubbering worse or better with this map comapred to the -059 map?

Glad to hear that overall it was an improvement. Once in a while a get it right :-)

I think the blubbering is slightly more just in that area but everything else is better.
Thanks again - JH

See if this is any better.

King B · 10-13-2009, 12:32 PM

Will do, as soon as I get home from work.
I'll let you know, and
Thanks again - JH

Got to ride today.
Not sure if it will make sense but I think it blubbers on decel more now (Unlike me, I blubber all the time).
It was mostly in 4th gear, backing of at 40 or so (back roads). It does happen in all gears from time to time. I'm thinking it's between 2500 and 3500 RPM (W.A. Guess).
All in all I think the last map was better.
Good excuses to ride however. It's getting cold here.

Ok, one last try. When you have a second you can see what happens with this one. If this doesn't do it then we may not be able to fix it with mapping.

Thanks for the quick response.
I will try it.
Worst case I go back to your first King B map (It was pretty dang good)
Thanks for all your help.
