PCV Map Help

[Hollywood448]

I installed the PCV today and it was loaded with a map from fuelmoto for the v&h slash cut with stock air box map which is my setup for now. Every now and then in when I roll on the throttle it will hesitate then take off. I have only noticed it in 5th and 6th gear at 2000 rpm. It is almost like a misfire. I have not noticed this before so I think it has to do with the PCV. It does not happen all the time so I think I could live with it but if I could do something on the map to fix it I would. Any advise would be nice.

well part of the problem could be the rpm you are in with the gear you specified, you should try to keep it at around 3000 rpm and then see if you have the same problem, IMO if you are in 5 or 6 at 2000 rpm you are lugging the engine which probably doesn't help

It only at that rpm that I have noticed. I would not think 2000 rpm would be lugging the motor, 1500 and below yea. I am not going to full throttle, I am just rolling on it some.

well I have found on mine that it is not too happy at times below 2500 rpm, I usually keep it at around 3000 rpm, that said you can go in and adjust the map for that rpm at those gears, I would decrease to lean it out to begin with, if it get worse, just increase and see if that makes any difference.

Yes Smokey is correct 2000 is on the low side of RPMs for a 1700, at least for my 2010 Voyager.

I would agree with the above....my 2012 Voyager likes to be over 2500 rpms pretty much all the time, in all gears. If you have not already done so, there is a very popular throttle mod for the 1700's that really helps with quicker acceleration as well...and it makes a substantial difference in performance. Super easy to install and you can get the grip pre-modded for you, or in a DIY kit by several members here.

I have read about the throttle mod several times on here. I just picked up my 2010 Voyager this year and this forum is the first site I go to for info. Altho I don't post much I read most of what is posted. I am a noob when it comes to wrenching so this site has helped me and I like working on the bike to learn. To get back to the point, once I understand how the throttle mod works then I may do that as well. For now, the PCV is my new toy to learn. With all that being said, how would I adjust the map for one gear? The map looks like it adjusts the fuel for all gears across the rpm range.

Don't adjust anything if you don't know about what the figures do, read what the others have said, the bike will bog if you want to accelerate from 2000 rpm, the big v twins are not happy at that rpm, keep it at 2500 and above and you shouldn't have any problems. I also noticed that I get the best gas mileage at 3000 rpm in 4th or 5th gear.

I have some understanding about what the figures do. I know not to adjust anything unless I know what i am doing. I feel my first question was answered but my next question still stands, how would one adjust for just one gear?

You can't on the PCV maps, only for throttle opening and rpm, so I would guess that it would take some trial and error at different openings, either that or a dynometer, which is around $350 to get proper mapping for your setup. Or even better, don't do roll ons at 2000 rpm in 5th or 6th gear, as I stated the big twins do not like lugging the motor, which is what you are doing.

The throttle mod is super easy...if I can do it anyone can. It will make an immense difference in your ability to quickly and effortlessly roll-on and get into the higher rpm range. It was like a whole different bike once I did that....

Smokey, I got your point the first time about lugging the motor. I respect your statement and your advise. I feel there is a bigger issue than just lugging the motor. I would understand this happening if I went to full throttle but not when I just open it a little more.

[smokey]

Okay, then take a look at the line for the 2000 rpm and follow it across, look at the throttle opening you think it may be at as you try to accelerate and then either increase to richen, which is what I would do, by about 2 or 3 and if that makes it worse, then go the other way. if either way doesn't do anything then go to the next setting, so if you previously tried the 5% throttle at 2000, go to the next percent and try the same thing, just remember it is always best to start out richer than leaner.

[Hollywood448]

Can do, and thanks for the advise.

I should add though that I take no responsibility for any changes you make, I am merely offering advice based on 44 years of doing my own wrenching. I am sure there are better experts on the forums when it comes to programming those maps.
