i put in a power commander V a few days ago. its a little slower to fire off than i think it should be and it has a little decel popping. are any of you pcV users having any issues like this and what did you do?

heres my bike info
2012 SG, screamin eagle heavy breather, catless stock head pipe, 3.5" slip ons, new plugs, new battery, pcV map 15-011-058

 

Are you waiting for the light to go off before you hit the starter button ? If so try not waiting for the light to go off and hit the starter immediately. I've had my PCV for about 4 years but memory tells me this topic was discussed.

 

it does the same thing whether i wait for the light or start it immediately.

 

Turn your grip on/off switch to off. Then hit the starter button and switch to on at the same time. Makes a big difference for me on how quickly it starts

 

Did you re-set the throttle position through the PCV?


Decel popping:
The image below is just for instruction. The first column represents the throttle in the Off position. The column left of that shows the RPM.
This example shows No fuel being added by the PCV in that range. So when you let off the throttle, (between shifts or slowing down) you get the popping.


The following is just a suggestion.
First, make a copy of the map you are using.
On the copy, go in to the "0" (ZERO) column and add Fuel in increments of five (5) from RPM 1000 to 4000.
The PCV will add 5% fuel in this range and in that throttle position.
Re-name and save the file. Load it in the bike and ride it.
Take note of what RPM the popping if any is there.
Repeat the process.
This will eliminate the Decel popping. I ended up with adding 10 (ten) in this range on my bike.


Good luck!

 

Hmmmm....never paid alot of attention to how it fires off....Unfortunately, you have just put this in my mind. LOL ....Having said that, I haven't noticed any isssue with it, but I do get a little decel pop sometimes because I tend to "blip the clutch in" and change gears without fully rolling off the throttle----I'm a quick shifter and tend to ride in higher rpm range and I love letting the engine slowing me down versus alot of braking. When I release the throttle fully, pull the clutch in, and shift...no decel pop.

I was told my quick shifting without closing the throttle was just leaving a bit of gas/fumes and it was burning off..thus the decel pop

At any rate---it doesn't bother me...my Deluxe did it for 7 years and I had no issues. I'm happy with PCV

 

Well, my older sig bike has PC 3 on it, but the bike runs great even with decel pop. However, I like the decel pop and the kid in me doesn`t want to change it.

 

Are your O2 sensors still plugged in?

 

Sensors are unplugged with a PC-V.

 

FYI - if you have individual maps for each cylinder, you will need to follow Sinthroid's instructions for both cylinder maps
