How beneficial is it to install a PC on a 5th gen with a 2 Bros slipon and K&N air filter? What can I expect to gain? Any low end improvement? Also, if it is worth it, which PC to choose (PC2, PC3, etc.)?
It depends on your expectations. I have a PCII, with a slipon and K&N similar to your setup. My biggest gripe was off idle fueling. The PCII cured that using one of the canned maps for regular gas. So it is worth it to me. However, when I tried to use the canned map for premium fuel, it was terrible. The occasional light throttle hesitation was bad, Bad, BAD.
Unless you're prepared to dial it in on a dyno ($300 or so), don't bother. My dialed in PCIII really smoothed out the power delivery (reduced/eliminated flat spots) so it feels like it accelerates more strongly. Also, the slight richening off idle reduced the light switch fuel delivery a bit. Very worth it, to me, but I've got $500-600 in the package to make it right.

I don't entirely agree.
While time on a dyno would make a big difference and be ideal, I found that using a downloaded map which I then subsequntly tweaked gave me exactly the same benefits you've mentioned. All I did was tried a few 'likely looking' maps, evaluating each one by asking "Is this better or worse?", and when I had a map that felt pretty good, I disconnected the PC to make sure it really was better than stock. Then I concentrated on just one area (revs vs. throttle opening) at a time, modifying the map until it felt better. It wasn't as easy as buying dyno time, but it was definitely worth it. Total cost was $150 for a secondhand PCII, and a few hours of riding time, spread over a few weeks.

:+1: I loved what it did to my bike - a Micron slip-on, K&N, de-snorkel and flapperectomy, along with the appropriate map made the bike a helluva lot snappier and well-behaved... so yeah, it works. :wheel:
PC worked well for me. Made the throttle a bit smoother. I too spent the money to have it tuned on a dyno. It was a bit better still. Then I
added a Turbo City FPR. Made it too rich so I took the PC out thinking I would have the whole package tuned again on the dyno when I had the money..... That was three years ago. I like the FPR mod better than what the PC did for the bike. Posted Image
my bike, with K&N filter, PAIR block off, and Custom pipe, was running a bit rich.
Added a PCII for $50, used the Staintune+K&N map, all is good. Running a bit leaner than before with much better fuel econ. Smoothed out power all through the range.

AB did you make any custom values to the Staintune map? ... I tried it, but it ran much thirstier.
I got a PCIII and used the canned map for a hi-rise Hindle and K&N.
Though I got all 3 items at the same time, so I can't vouch for the single item, I found that all three definitely added what seemed like 10% power, great sound and very smooth operation.
Didn't affect mileage either, that I noticed.
I recommend; not too expensive, easy installation and modification.

here is the chart for my bike before and after the pc3 being tuned...
Is it safe to assume that the consensus is that if you are going to install a PCII or PCIII that its best to not use the Turbo City FPR. I have the TC FPR and I am not really happy with it. I am in the process of picking up a PCII from a board member and obtaining a modified map from another board member and then hope the bike performs a little better. I was looking at Stephens dyno chart and it looks really good as far as I can tell. I should have some data in about two weeks.

Here asking questions again.

Thanks.
I had PCII installed on my '99 with Hindle slip-on & K&N and it worked beautifully for 2 seasons (had it tuned on dyno, was pretty smooth with 100.1hp , can't remember torque). After 2 season i put bike away for the winter & could not start it in the spring. Turned out it was PC so I'm guessing it could have been low temps in winter that killed it. Pretty disappointed because of that and probably won't install another one on.
My PCII also calved after 2 seasons. It ran very rich and could not be salvaged. So I replaced with PCIII and had no troubles. Someone here has it now and hopefully still good 3 years later.
And yes, it was worth it. Smoothe, efficient, easy to download the right map from the website... No downside except the PCII failure.
I had K&N & Hindle hi-rise on '01.
Add me to the list of satisfied P.C. users. I just recently picked up a P.C. III and regret having not picked one up much much sooner.
My biggest caveat would be to ask "What exactly are you expecting to get out of this?" If you are looking to add tire shredding power with a little black box....yeah, not so much. Yeah, you can probably pick up a few horsepower, but for me it was a rideability mod. I was sick of the bottom end on/off switch, and a canned map for a stock 5th gen pretty much cleaned it up. A little tweaking on the map and I'm even happier.
Also how deep do you want to get into this? P.C. II is apparently more user intense with the additional feature of being able to modify the spark tables. The P.C. III you just hook up to the bike, hook up to the lap top, load a canned fuel map and you can probably get 70% - 80% of what you're looking for.

PCV--Autotune optional.
Code Dude,
Can a PCV be used on a 5th gen? I've only seen them available for late model 6th gens. Is the ECU wiring bundle connector the same on 5th & 6th gens? Can 5th gens be wired for individual map by gear? Maybe I should have just PM'd you with the question assualt...

Care to share your PCII map if you still have it? I've got a PCII and I'm running a canned map but I would prefer to find one that has been tuned for a bike set-up similar to mine and use that as a starting point instead of reinventing the wheel. Anyone out there with PCII map for a Y2k 5th gen with a 98 -99 catless headers, O2 elim, PAIR removed, de-snorkeled, de-flapped, BMC air filter, and high mount Motad slip-on?

Sorry, I had PCII installation & tuning done by a shop (in '06 or '07) and honestly have no idea where I stuck all the things . About the only thing I got is the hp/trq graph, which probably won't help you (I'm plannig to post it in my galley soon)
