PC3 USB vs. PC5
Here is what the important differences are as far as I am able to acertain:
please note my questions at the bottom of this post. 
***************************************************************
1. MORE COMPACT
Reduced size from PCIIIusb (less than half of the size of PCIII)
2. SENSITIVE TO MORE SOURCES OF INPUT FROM ENGINE
Gear/Speed input (allows for map adjustment based on gear and speed)
Analog input (allows user to install any 0-5 volt sensor and build an adjustment table based on its input such as boost or temperature)
With gear position input connected the PCV is capable of allowing each cylinder to be mapped individually and for each gear (for example: on a 4 cylinder bike with a six speed transmission there could be up to 24 separate fuel tables).
3. GREATER RANGE OF ADJUSTMENT
Unit has a -100/+250% fuel change range (up from -100/+100%). This allows more adjustment range for 8 injector sportbikes PCIII has a +/-100% range
10 throttle position columns (up from 9 on PCIIIusb)
Enhanced “accel pump” utility (increased adjustment and sensitivity ranges)
2 position map switching function built in (map switch not included)
4. AUTOTUNE EXPANDABLE
Auto Tune for PCV (all models):
“Auto Tune” kit will be available that includes Wide Band O2 sensor(s) and control box(es). It will plug directly into the PCV and allow automatic fuel adjustments.
******************************************************
How much use would the aditional latitude in adjustment be?
Can autotune be used with the PCIII? It costs about $200 for the autotune expansion.
The PCIII maps for individual cylinders but it does not have the capability to map separately according to gear or to map according to speed. How important are gear position and speed in tuning?
If I buy the LCD display, wouldn't I be able to store & switch between a whole bunch of maps whether I had the LCD connected to a PC3 or a PC5?

A used PC3 around here is b/n $150-200 shipped.
A good Brock's map will be better than anything you'll be able to
autotune yourself IMHO. LCD displays and such are simply scratched
by your laptop.
Save a few $$$ with the PC3 and spend it on other goodies

Thanks, S. You were riding with a PCIII around Mass. which is about the same weather and altitude as Milwaukee (Sea level) so I would think you would be the perfect person to get advice from. If I can get a used PC for 150 bones, the learning experience would be worth the possible cost of upgrade down the road.
Do you feel Brock's maps could benefit at all from any adjustments done by you with a PC or do they just seem perfect for your atmospheric conditions?
Also, don't forget - I may need a turbo tuning device some day and you can't get ready made maps for that (or can you?) Anyone think the PC5 might be a better tool for tuning to turbo?

I think your best bet before buying would be talking to a tuner.
That way you will know all your options and can set performance
and cost goals. Call Brock and speak to a tech there, or even the man himself-
they would have all the answers for you.
IMO for street riding a PC3 with a good map is all you need.

And what you MIGHT get 1-2hp out of all that special tuning?? I personally think a pc with a custom map done on a dyno will get you everything you need, that's a bunch of bs just to ride on the street and a few track days imo. If it were me, I'd learn how to ride the bike closer to its potential before worrying about that detailed stuff. Just get a pcIII like everyone else

It doesn't seem bad to me, because I don't have it.
I don't have BST wheels either

He asked for the opinion, and I'm not saying its bad in the right persons hand, but I speak as if it were me. No I wouldn't go through tuning each gear, etc bc I don't know how, therefore I could tear some serious shit up with that! Me not having enough "knowledge" in that area it would be foolish of me to get one

In the recent post about the sale on PCIIIs, Ninja Knight posted an email from Brock where he suggested that he may need to tweak his maps a bit to run at their best on a PCV. He further suggested that the PCV its self has not been proven. I'm sure Brock's opinion is worth a lot more than mine but IMHO, the PC has been through a few incarnations now and each one was better than the previous. I'm pretty confident that the new PCV will work as well or better than the PCIII. Just not sure how necessary the extra features are.
Good point made that I won't benefit more with either PC3 or PC5 if I'm not pushing the bike to potential. I try my best to be prepared for the future AMAP with what I buy though. Also, bragging rights comes into play, I have to admit.
Kind of a strange game I play - I could buy both PCIII & PCV after all the time I put into deciding which ONE I should get. LOL!

as I said in the other self tune thread, if you are just a street rider the pc is perfect, if you race, switch fuels, make adjustments, and have weather changing, get a Bazzaz or PC with auto tune

Can autotune be used with the PCIII or is it just for the PCV?

^^^Thanks, Silver 08.
I think I have enough info to make a decision now but there's no real big hurry. Sounds like if you're one of those people who loves to figure out every possible function of todays electronics the PCV might be a little more fun for you.
I could go with either one. It's either a great deal and proven success with a used PCIII or more versatility and a reliale history of products for a bit more money with a brand new PCV.
BTW, for Wheelie and all the other 'zuk riders, the PCV DOES NOT tune all eight injectors. It will do a better job on tuning 4 of 'em but you still need two PCs if you want a 100% tune. Bazzaz seems still the way to go on a busa IMHO.
