PCV V Experts-

Looking to tweak the PCV 5 map.
Getting the dreaded pop on decel at 2200 RPM.

I believe its a result of being lean... Want to look at what others have done..

I have the K&N with V&H Slash cuts.

If you could send me your maps. I would greatly apreciate it.

I'm going to research this and play with the 2250 range...

In the 0 column closed throttle start at 1750 to 6000 add 5 , this will add a little fuel off idle and quench the pop by adding the extra fuel. Test ride and go up in increments of 5 until it stops. I still have pop at precisely 2100 rpm. The injectors turn completely off at 0 throttle.

That's the kind of input I was looking for ... I would think it is dropping out before full closed throttle.. 2% or 5% columns as well.. So I was thinkg of adding there as well...
Do you have a map that has been tweaked that you're using... Can I get a copy.

I can't remember the map I hae but it might be David Sheiks...

I am using a Dobeck Performance EJK processor. I am basing my opinion on how to fix your issue from my countless hours of research. You can tweak your map easy using the Dynojet software. To get truly the most out of the bike you should get a dynotune and they can do a custom map.

Be aware that even perfectly tuned bikes can still pop on decel. I switched to 87 octane used the settings my processor came with and I am getting 41 mpg. The bike pops a little when the pipes get hot in stop and go traffic, usually a single pop when I am in 3rd in a closed throttle decel. A little throttle control and I have been able to reduce pop to a very minimum.

The closest Dyno is 75 miles away and I plan on the full run when it warms up.
The shop is not ready yet so it's out at least two weeks.

Thanks

Gary, honestly with the mods you have, i would hold off on a dyno run at likely $350. Tweak the 0 throttle column and 2% column yourself. The reason being if you add an Air intake later, you will need a new map and the one you paid for will be worthless. My 2 cents

Thanks to all who sent maps-

The one I was running had very minimal fuel added down low. Went to the Best map so far and for my VV I think it's a bit rich, have to monitor mpgs. . Still getting just a slight pop on decel. But this after being on the highway and rolling off throttle quickly. All the other popping is virtually gone. Read where three increments is equivalent of a jet size. So I will be tweaking by the 2/3's. Most of the riding is 3000 RPMs or below so that is where I am going to focus..

I'm glad I read this thread as I have the same issue with the exact same pipes with the K & N and am having the same problem.

Did you plug the AIS ? I have read a post on blocking the AIS system http://http://www.vulcanbagger.com/forums/showthread.php?t=29721 it helped on mine so now I'll try what was posted in this thread. If you don't mind I'll try changing my map also but if you find a cure please post it here and I'll do the same.
