Is this for the gen 2 bikes ?
I'm going to do this swap tomorrow. I hadn't considered the issue with hooking up the PCV to the old 16 bit wiring. I'll probably cut the PCV connectors and make them work. I've got my old PCII, so maybe I can just use those plugs...
Thank you so much for posting this!
You could use the connectors from your PC2 and replace the ones on the PCV but by doing so, you will destroy any resale value it has (as well as the warranty). Spend the $35 on connectors and make the adapter. It's not too difficult to construct and it works! Then, if you ever are able to get your bike dyno'd using the ECU Editor rather than the PCV, you can resell the PCV.
If you do end up using the connectors from the PC2, remember that you will need a jumper wire between the PC2 connectors. The PCV only has 8 wires. The PC2 has 9. The extra wire is the ground to the external fuel pump.
Well that would be a problem then. I was thinking that it had the same connectors as the PCIII USB but after looking a PC2 up on ebay I see what you mean. I guess he will have to buy some 16 bit connectors after all. Might as well buy the 32 bit connectors as well and build the adapter.The Pc2 connectors plug in at the ECU, not the throttle bodies!
If you have an '01 you can just plug the 02-07 ecu in and swap the rotor on the crank to the 02-07.I'm new to this conversion. So you can keep the 01 harness intact but just change pins. Also any power gain off the bat or response in busa. Also to use the Pc5 just plugs in or u have to modify for that to work? I'm not good with electronics never have.
I'll answer this the best I can, as it's been over a year since I've played with this stuff on mine.Informative post! Thanks... Btw, what are the issues faced on the 16 bit ECU & in what way does one benefit with the 32 bit?
Thanks for the elaboration mate! So for someone who is not looking to install new mapping on his '99, but is content with the stock, unrestricted mapping, the 32 bit conversion is really not necessary isn't it?I'll answer this the best I can, as it's been over a year since I've played with this stuff on mine.
I changed my '99 to the 32 bit because I wanted to run a newer Power Commander (PCV) with Auto Tune, etc... The 16 bit system will take a PCIII. A word of caution on that, I later found out that the '05 and '99 use a different harness to the throttle bodies and therefore the PCV doesn't just 'plug and play' as it should. I ended up having to get another set of '05 connectors to put on my '99 so the PCV would connect. (Can you say "PITA"?) You could do this a few ways, but that's the direction I took.
Another reason, and this is where I'm the most 'fuzzy', is that I seem to remember reading that the 'ECM hack' only worked on the 32 bit computers. I wanted the ECM hack for removing the speed limiter, retarding ignition timing (on boost), making the rev-limiter a 'hard-cut' and raising the redline from 10,900 to 11,500.
All the best,
If you're content with the way the bike is now I wouldn't change, but that's just me. If you're running a stock, or mostly stock bike, I don't think there's much, if anything, to be gained. If you want to change the mapping then a PCIII USB (light years better than the PCII) can be installed on your 16 bit system. Keep in mind also that if you update to 32 bit then your bike will be restricted.Thanks for the elaboration mate!

I think you'd be fine with the existing PCIII. It really only needs the injector wires, the TPS and a way to count RPM. Since the PCIII connects at the throttle bodies the re-pinning of the ECM should have no effect on what wires you're hooked up to. The biggest difference between PCIII models is the connectors they're sold with (and obviously how many cylinders they'll adjust). The PCIII and PCV let the ECM make it's normal calculations and then simply intercept and modify the output to the injectors.I have a 01 with a PC3. If I do this conversion can i still use this PC or have to get one for a 02-07?
