583CE Cam install - Breaking up in Mid Power range
This ones got me confused. Installed the new cams and the FP3 Wideband on 2011 fat boy lo. Stock heads. Bike started right up, revs like a beast than took it for a ride and under load its breaking up in mid RPMs but feels sluggish overall. Flashed the ECU for the cams of course but something seems off besides the mid rpm issue. Always had carbed bikes so it seems like an AFR issue but Im used to turning screws to fix that lol. Also removed stock baffles on the Big radius 2 on 2's at the same time. Anyone have any ideals?

So need to call Vance and Hines and have them make adjustments to the tune to fix? Being that I have the FP3.

You installed cams and removed the baffles, but are using the tune it had previously? With those changes, you should have gotten it straight to a tuner to have it dyno’d IMHO.
Definitely get ahold of V&H and talk about a map change, but give serious consideration to taking it to someone competent to have it tuned properly.

the FP3 said it had the cam selection so I flashed that first with the new cams selected before I started the bike. I also installed the Wideband PRO at the same time figuring that should complete the tune in the auto tune sessions. I figured with that combination from everything I read that I should be good. Apparently not. Will update after I talk to Vance and Hines today.

I wasn't aware FP3 had that option, does it give you the ability to log data now?
What about live data on your screen? look at your AFR's while driving down the road, where are they? where is the MAP? where is the TPS? at the rpms where its not running right
I had these guys bring me a 2010 wide glide recently that had the baffles removed on the same pipes they thought the Power Commander 5 had failed. I used a Power Vision license and a tune from Fuel Moto to try to tune it, It was so far off the bike would barely run, I had to change the settings dramatically from what it actually was to get it to run right, looked at the data from the wideband O2 sensors and it was going as lean as 18-19:1 in the midrange areas. I ended up reinstalling the baffles, and it tuned in pretty easy after that
Bottom line is you need data from your bike to make educated changes to your bike to tune it properly. The best place to get that data is on a dyno, period. somebody guessing on what you need from the other end of a tech line or answering an email is throwing darts blindfolded at best. The way this auto tune technology is marketed is a crime

Were you running in auto tune mode? did you apply the changes? Did that make it any better? Auto tune can only adjust so much at a time

I put the baffles back in after the research on reversion etc. been going back and forth with Vance and Hines. They are getting the tune closer but inspecting the new plugs I put in, its still running rich. The days are about 68 degrees at best outside right now so its hard to get the bike to 180 degrees for the auto tune to start doing what its supposed to do. Wonder if I can upload the map to my computer so it would be easier to adjust. Its definitely an AFR issue in my opinion.

Didn't know you had two threads running on the same thing, shouldn't do that, but anyways here's what I posted over in the other thread...
Do you know what your CCP is..? these cams don't like hi compression.. 18* ivc on a103" wouldn't be my choice of cams... Could be a detonation issue.. Check your tuner to see if it is picking up spark knock events..
