A friend of mine has an 07 Fatboy. He is having lots of trouble with his PC USB III. It's stuttering (for lack of a better term) when he rolls on the throttle it hesitates, then takes off. He is DONE with it I think. He's tried maps from Jamie at Fuel Moto, he has tried maps from the Power Commander site, he even paid $175.00 to get the bike dyno tuned. The tuner guy said he's never come across the problem and can't figure it out.
He has unhooked the PCIII and is running with Stage 1 D/L-- SE High Flow A/C Kit--VH Staggerd Pipes. After he unhooked the PCIII the stuttering went away. But I say it's still running lean..yes/no? You guys with more experience than us, my question: "Is it possible he has a bad PCIII Unit perhaps, or anything you can think of?"

Thanking you in advance..
And Ride safe..

 

My inclination, since I am very happy with my PCIII, would be to think that he had a bad dyno session and that he needs to go to a qualified tuner. Did he go to an approved dynotek tuner? I rarely see anyone on this forum comment that they are extremely happy with a canned map.

Soft06 is talkin about my Fatboy. I have had it with the Power Commander! All I have gotten out of this whole Power Commander experience is a huge headache and a lot of waisted money ($500) and time!

I have had this stuttering problem with my PC3 ever since I voided my HD warranty and installed it.

I thought that by changing maps it would fix the problem....NOPE
I thought that by changing pipes it would fix the problem.... NOPE
I thought that by getting it Custom Dyno Tuned would fix the problem ... NOPE

This past Saturday I had it dyno'd by a Dynojet Power Commander Approved Tuning Center for $180. The tuner couldn't tune out the stutter nor could he explain it. By the time I rode home I was so pissed with this whole Power Commander ordeal that I pulled it out of my bike. Then guess what happened???

No more stuttering!

My bike runs fine now. I might be running a little lean but if I'm not doing any damage to my engine at this point I don't even care.

 

I hope I didn't step on your toes Faction95 by placing this post., I was just trying to help.

 

Hell yes it's possible. If he's had it Dynotuned and the bike still doesn't run right, I'd suspect a bad PC3. I have an '07' FLSTC with a custom map from FuelMoto and it runs perfectly. Tell him to send the unit back. I once spent 3 hours trying to get a Linksys router to work on my computer. Tried everything I could think of to configure this thing and nothing worked. Took it back and got a replacement. Bam, worked in 5 minutes!. Electronics are funny things. That's whata warranty is for. Good Luck

I called Jamie at FuelMoto. He was really helpfull. I'm going to send him my PC3 for a replacement. Hopefully this new PC3 will work.

 

I hope you saved your custom map from the tuner... so all you have to do is load that onto the new PCIII....

 

Shouldn't the Dyno Tuner guy still have a copy as well?

 

I saved it on my laptop before I unplugged the PC3 and removed it from my bike. I'm going to call the dyno place to see if I can get it redyno'd after I have the new PC3 installed.

 

Dumb one, but make sure that the accerator pump is off!
