Hi,

a newbie here - 1st question as a new member.

I have noticed that (probably due to emissions testing) there is an annoying "switchiness" to the revs on the Blade betwen 2800-3000rpm.

Have those that have fitted a PCIII seen this noticeably disappear?

I am not after extra power and have not even looked at an after market can as yet (suggestions gratefully accepted) but would love to try to eradicate this annoying on-off feel right in the middle of the low-speed crusing rev range. If a PCIII fixes this then it will be my next mod.

thanks

Power commander might smooth it out. You can also try the FLAPPER MOD. There's the simple flapper mod which just requires you to plug a hose and keeps the flapper open. Then there's the un-simple flapper mod in which you remove the physical pieces. Personally I suggest #2 even though it's a pain in the ass -- mine has really smoothed out the low/mid range with the phlapper gone.

I had the same on mine, between 2500-3. At 4k miles i put a yoshi RS5 can on and that improved it alot but not perfect, at 6k miles i put a pc3 on and its mapped with the map from the pc website for the can and k&N air filter thats in, that smoothed it a bit more so its nearly there. But it still has the problem but now its easier to ignore, i think the only solution would be a custom map for the pc3 from a dyno run. I did the flapper mod and found that it didn`t smooth it out.

You`ll find that the exhaust valve is the main part of the cause, if you decide to keep the stock exhaust i would disable it and see if it helps reduce the fueling glitch, its easy to do and easy reversed if you don`t like the effects.
