HELP!!!!!!!

Can anyone tell me the difference between the PCII, PCIII, and the PCIIIr.

I have heard quite a few people having problems with the PCIII lately, has anybody heard of this?

Also my mechanic want's to put on a PCII instead of the III, or the IIIr any thoughts?



I have an Akro CF pipe and need to do some tuning ASAP.



Thanks.



Jet.

Get the PCIIIR. It will allow timing changes if you so desire. The PCIII will not. There have been some issues in the past with both the III and IIIR, but Dynojet seems to have worked most of them out. One thing to be careful of is, don't allow the wires to be pinched by the gas tank when you lower the gas tank. The pinch plus any vibration can eat through the wires causing malfunctions.. The IIIR is only a couple bucks more that the III so if you can afford it, get the IIIR.

The best place to buy the Power Commanders is www.spencercycle.com

Unless you get a mechanic that does a lot of work on 12's, I've found not many of them know what they're talking about (in my neck of the woods anyway). I had a guy at a reputable local shop tell me to put an Akro slip on on my 12 instead of a full setup cause it would make even less power than the factory pipe, I said, "wow, I didn't know that" <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/wink.gif ALT=";)"> I'm sorry but it's hard to argue with numbers and dyno sheets. I think the best way to find out info on our bikes is to be right here. Get the R model

Hmmmm. PCII for the zx12r. If Im not mistaken we never built one of those, so this mechanic is either REALLY good and is going to adapt some other PCII to your bike or he is full of it.



Here is the break down on the Power Commander line.



PCII is based on sensor offset technology. Basically is goes in between your ecu and the various sensor on your bike. Once the PCII is plugged into your bike we modify the signals that each sensor is sending to your ecu in order to "trick" the ecu into changing the amount of fuel is gives the bike.



PCIII is our next line of Power Commanders. It goes in between your ecu and the injectors on your bike. Once installed we watch what the ecu is sending to the injectors and modify it directly. This method has the benifit of being very precise, if you want 5% more fuel you can just add 5% more fuel instead of trying to "trick" the ecu into giving you 5% more like the PCII.



PCIIIr is the same as the PCIII in fuel functionality but it adds timing adjustment also.



Silver: Damn I need to put my stock exhaust system on there and get all my horsepower back that I'm losing!!<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/laugh.gif ALT=":lol">

Hey Tear, you need to post your address so all of us Power Commander Troops can send you a Christmas present for all of your help. It really is great to have someone on the boards that not only can lend a Technical hand, but also has a ZX12R. What a combination <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT=":)">

Jetman:



In this area there is only one place that I know for setting up your pc3, DPE Racing, they have done most of the remapping on everyones bike in this neck of the woods. Go see Dave tell him I sent you and he'll charge you double ha ha LOL. No really he can help you out, there is a pc3r at Brampton Cycle Torbram and Steels s/e corner ask Bob at parts he has it in the back. Actually Cycle Max is right next door they have a dyno also should be ok for you, I make over 200 hp so I outgrew him, See Jeff he's a good guy also. Give me a call at home 416-743-3683 I think everyone is going cruising Friday night.

I don't want to come across as a know it all, I really appreciate your help Tearinitup. But......



The first few products for the 12 last year were in fact PCII's a few months later Dynojet came out with the PCIII with the new style of injector control. Hank was one of the first people with a ZX-12R with a PC product, he donated his bike for the first PCII installation (first that I am aware of).



However the PCII did not last long before going to the PCIII.



I hope that helps people.

There was also one for the Busa and still seems to be available.

Let me reword this. I do believe that the first Power Commanders for the 12 were called PCII's, because we hadn't decided to call our new technology PCIII yet. Rest assured that ALL 12 power commanders use the technology that we currently call PCIII and PCIIIr. We never built a "sensor offset" Power Commander for the 12. I personally worked on Hank Booth's 12 and his turbo'd Busa for that matter (280's hp at the wheel--ouch).



Busa's - we have never built a PCIII for them. HAHAHA One more reason to own a 12. <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT=":)">

Thanks Tearinitup, that makes much more sense now.



280HP Busa, WOW!! But then again, I think they need that much to keep up to the 12. LOL



Thanks for the feedback Tearinitup. I am totally impressed with the difference the PCIIIr has made to my 12. It has smoothed it out so much that it feels like a completely new bike in the corners, I am still amazed at the smooth response improvement.
