Power Commander to get rid of the stink ?

Is it realistic to expect reduced stink by using a PC ?
The bike is stock.

The map is completely separate from the unit, as I understand previous posts. Is there a 'map' to lean the mixture across the entire range ?

This is cold country and the stink is pretty bad during warm-up. Different fuels do not seem to help.

Thanks for the feedback.

EDIT:

On second look, there doesn't seem to be any help for the PCIII in there.

I added a power commander to mine when I added slipons. I live in MN with many cool mornings spring and fall. When running stock I would get to work and my office would stink like exhaust for the first couple hours from my riding gear.

Now with the PCIII and the Dan Kyle Sato tune it has improved greatly/huge. Plus the trottle response is better. Shoot the whole bike runs better.

I still get the smell a little but greatly reduced.

Does one brand power commander work better than the other?

Or does it depend entirely on the fuel map?

Tuning your bike based on stink is not a good idea. You could easily end up with a poor running bike (definitely sub-optimal) and eventually a damaged motor.

The best (and I believe only) cure for the stink is a 900RR exhaust conversion or 4 -> 1 low exit exhaust.

IMO, any other alleged cures are really just different riding conditions, clothing, body shape, windshield options that are more or less prone to highlight the problem.

I have not done the exhaust conversion yet though I probably will. I love the way it runs with Satos, PCIII, and the Dan Kyle map so I'm hesitant to change anything even though I have a nice 900RR header with a Black Dragon custom can ready to install if I decide I'm ready. If I do swap the exhaust, I'll also get a custom map done for it to ensure I'm getting the most out of it. The expense of getting the dyno tune has been a deterrent. I expect to actually lose performance somewhere if I switch from the Satos, one reason I have not done it.

Ive wondered about the exhaust smell issue plenty of times, every chick Ive dated tells me I smell like exhaust from every bike Ive had..... Nature of the beast is what Ive came up with. Its like a fancy cologne that says "I rock"

, and I'm a Bada$$...... My wife says the same thing about the stink. But with owning all classic bikes up to this point, she is so use to it she no longer complains.

I ran my bike with the Two Brothers single can....and the PCIII-USB zero map. (didn't have time to load the new map)

The bike ran horribly rich at idle...and stunk bad. Installing the correct map made a HUGE difference.

You don't have to 'lean' out the PCIII map to make it not smell, you just need the bike to run right....not tooo lean, and not tooo rich. (and even then....its going to smell a little bit)

.........I'm sure if you purchased the PCIII-USB and had a custom map made... it would smell less.... but why not buy a nice exhaust first --- then have the map made. Buying the PCIII, then running a pre-made map not tailered to your bike (even though it is stock) will only get you in the ball-park. The only true way, is to have the map custom tailored to your bike.

^ Agreed. He may be one of those guys that accually likes the quiteness of the stock exhaust.

I cannot say as I never had a PC3, But I live in Nova Scotia (basically the same climate as you) and I only rarely ever had the exhaust stink problem, Maybe a hand full of times I can recall saying to myself that it was bad.

I had an 04 with stock cans and everything and never had the problem, or maybe I'm just not a sensitive as some people on here haha, Even when it was bad it never actually made my jacket smell like it.

Anyways, I would think changing the map to something that runs leaner would help abit, but you'd have to change the exhaust to get rid of it almost entirely (single pipe, low mount) but then again I'm just guessing.

A stock 919 with an exhaust mod and a map created for the 919 with that exhaust sorta has a custom map for that bike with that exhaust.

If you think Hondas vary much from one identical bike to the next, I think not.

I could be wrong and invite anyone with first hand dyno experience to enlighten me. Until then, I doubt I could do any better than the Dan Kyle map with my stock 919 and Satos.

I haven't heard any of ya'll mention the PAIR block off plates. Those are what made the stink entirely go away for me. Like....completely. I got home after riding for four hours nonstop and had my wifey do the ol' sniff test, and NOTHIN! Best $28.95 I've spent so far on the 9er.

Questions about installing them, let me know. I just did the mod two weeks ago.

Oh, and as strange as this may sound, switch to running just regular 87 octane gas. No high octane stuff, that makes the stink worse, too.

.... thats weird as the PAIR system pulls fresh air in allows the catalytic converter to do its job better by burning off any excess stuff. I may have to try getting some caps to temporary try it out and see if it gets rid of stink tho.

Ive got the single out low RR setup and I still stink, yes I shower. I did the mod cause I like the old school look though not for the stink. The stink to me has just been A part of riding with all my bikes... I just thought thats how it was. Intersting post about the PAIR plates I would've thought they'd have the opposite affect.

+1, I started running super, then plus and now I'm at regular and the stink is gone. (I never had it that bad to begin with, lucky I guess)

I agree, but as to the variance, I've NEVER had the stink. Before PCIII, after PCIII, then even when I put the new Delkevic pipes on.

Thanks for the feedback !!

Wow ! Thanks for the info.

The Dan Kyle map with Satos seems to be the standard. I indeed like the silent stock cans. But if I have to choose I prefer less stink over more noise.

I will keep using low octane from now on.

Maybe try the plates as well. Interesting concept.

ya... the 919 only needs 87... so run it... i have found running premium (91) results in HORID STINK outta my bike.

Also you dont have to buy the pair places... auto zone or any other autoparts store will have vacuum caps that will work on the stock pair housing... ill pick some up next time im at my local auto parts store.

Of course running lower octane fuel is going to result in less "stink;" higher octane means it's less combustible, so there fore more unburned raw fuel in the exhaust (that's how high octane fuel prevents pre-ignition in higher compression engines.)

And you know what I call a guy that is worried about how he smells after riding his motorcycles?
