PC V help
Just installed a full Akro shorty stainless system and PC V. Installation went smoothly and took about 5 hrs including installing PC V, new oil and filter, new front brake pads and airfilter replace.
I have 3 questions following the install:
1. I tried Power Commanders 004 map but got a big hesitation between 1500 rpms and 3000 rpms. I then tried the 502 map and this has improved, but still needs some work. The difference between the 2 maps is basically less fuel in the 502 map across these rpm ranges (ie the numbers in the 502 map are lower) so my question is, should I just lean out the fuel a little more across this range and see how it goes?. Ultimately I would like to take to a dyno and get my own map, but this may not happen for a while. (NB O2 sensores have been removed, and I have changed no settings on the PC V).
2. I have the OEM quickshifter?. I am assuming, the PCV settings don't need to be changed to 'quickshifter installed'.
3. Do I need to block the pair valve? I have done some reading on the site re this and can't work out what the difference will be and why it needs to be done now that I have a full system. How does it introduce more air into 'the system'? Via the airbox? If so, I suppose I should block off?.
Recommendations for those contemplating this:
- a very good tool set with many types and lengths of socket extensions
- a low range torque wrench (I had one that started from 19nm - but you need a lower setting than this)
- fit the PC V 'in line' as it says. I missed this 'minor' point and spent 10 mins trying to work out why it would not start!
- I did it without a bike lift, just used a rear race stand. Was a little uncomfortable but no real issues
- when you hook in the PC V, the TPS wire you need to hook into looks yellow under white LED torchlight (well it did on my bike anyway). Took me a few minutes to work out that it was really a white wire.
It is such a different bike now. Not much louder from behind unless I open her up apparently, but the noise almost gave me a headache in the first few days of commuting on it. The bike feels as light as and absolutely flies now. It is a missile from 3k rpm rather than 7k now. Uses about 10% more fuel, but who cares!
thanks in advance
