I found mine running at 4% @ closed throttle. I reset it to reflect 0% and now I get very minimal popping on decel. It was not backfiring b4 the reset. Pwer commander said that it could happen and makes sense. I told him I want a custum map and he said if I dont do that I could try this:

Power commander recommended seeting 0 throttle position values from 2000 rpms to redline to -30 then -40 then -50 if this does not work go the other way +30 then +40 , +50 til decel pop stops.

or

I might try what Rhubarb did..

 

I emailed Jamie at FuelMoto with my decel popping issue just to see what he had to say. He recommended that I set 0% throttle from 1750 to 5000 RPM at 15. I did that today and I am unable to test these settings because of the heavy rain we are experiencing right now[:@]

 

I have asked this question before but have gotten mixed answers, so I thought I would try again. I plan on getting a PCIII in the future, but now is not the best time. The only issues I am having are the following:

Minor pops on decel
Sometimes when the RPMs are high, if I decel then hit the throttle I get a pop or backfire.

These things are irritating, but if they are not causing damage then I can live with it for a while. All the dealers I have spoken to have said it will not cause any damage. You guys seem to know a lot about this stuff, so I thought I would ask yet again.

thanks,

I am no expert but:
Is it fair to say you have the stage one download? I did not see you mention a new MAP or custom tune.
What im getting at here is if you do have a canned MAP it sounds like you need the SERT or PCIII to install a MAP perfect to your set up.
Im sure you already know this.

Check your plugs for lean. Its easy and will tell you if the popping is damaging.

 

What do I need to look for on the plugs?

I currently have the stage 1 download and I plan on getting the PCIII, but just wanted to wait a bit so I can save up the cash to buy the unit and have it dyno tuned at the same time.

On the left click spark plugs and the VTX

Black, rich
Tan, good
White , lean

 

That is one comprehensive list of plug pictures.

Thanks for the info, I'm gonna hang on to that one.

 

Checked my plugs, mine look like they are somewhere between #19 and #23 (good to OK).

Does anyone know if adding a PCIII will affect my factory warranty. I still have 1 year left so I don't want to void it.
