PCIII Install - Frankenstein's way

Luv2cruise · Sep 16, 2004

I was ready to install my PCIII, using Frankenstein's "Perfect PCIII Install" modifications. Being a little afraid of making changes to the manufacturer's instructiions, I called Dynojet and read to the technician the entire post decribing the unsteady TPS signal during custom mapping. I informed him of the changes I was planning on doing, splicing the gray wire to the yellow at the ECU and splitting the ground and splicing the black/white to the black/blue at the ECU. He stated that they strongly recommend not modifying the install instructions. He said he had no way of knowing if the changes would damage the ECU and advised me not to do it. I installed it per the instructions but haven't ridden it yet. Being pretty new to this site, I was wondering how many others have done the modified install. and if anyone has had any problems with it. Also, if you have done the regular install. were there any problems with mapping? Thanks

I did it, and noticed a difference. It's not a big deal... just connecting to a different location on the same wire (via a better, soldered, connection). I wasn't too happy about how little wire there was to work with, however.
Dynajet pretty much has to say that, so people don't return pcIII's with the wires cut short...

I also used Frankensteins method, I think that it has helped out alot. The bike runs noticable smoother than when I had it set up according to DynoJet instructions. It is a pain to do though, not much wire slack to work with. I think that it is worth the time and hassle.

I didn't think the hardwiring was difficult at all. As mentioned above, the toughest thing is working with the short wire length between the ECU and the main wire wrap. It's pretty tight. I opened up the wire wrap a little bit to give me some more room to work. I also popped each of the wires that I was working on out of the ECU as I was doing the cutting/soldering. After the soldering is done, slide some heat shrink over the end and lock them back in place.

Just make sure that you don't make the solder connections too close to the end of the wires, or you might have trouble getting them to snap back into the ECU[/emoticons/emotion-2.gif]

Yes this is a very good mod! Not to hard if you are patient and the throttle reponse is indeed "crisper" and you can definitley see that you can get steady readings with the digital ground connected correctly.

I used Frankenstein's method and it worked fine.

I did the mod and then took my bike in for the dyno. It ran perfectly. Throttle is smooth as can be.

I did it too.The Franks way.

I spoke with dynojet too. Of course they have to say you cannot do that because they cannot deal with the liability. Not their fault.
In fact if you go to a good dynojet tuning center they know about this install trick - I got the idea from my place because they kept having troubles with the TPS read on all Warriors.

Here is another one: Maybe you want to try calling Yamaha to see if they can recommend putting on a Barons Bomber bar with internal wiring (that is cutting and soldering all handlebar wires) or a bigbore kit. [/emoticons/emotion-5.gif] Just kidding!
