I'm currently getting help from someone on the zx10r forums

I'm actually really surprise no-body has gotten one and ripped of the heat shrink yet, I've taken stuff apart that cost way more!! Ain't broken anything yet though. Maybe I'll go order one and have a sneak under it's skirt to see what's there... perhaps it's a sticker with a massive FU on it.. lol. Another reason to do micro photography

hahaha...i was thinking the same thing...what happens if i pull the heat shrink off and see that its incased in like colored epoxy. I'd be pissed. Wish I could just get a schematic from the company, but I don't see that going over too well.

If you get one and find out whats in it i will praise you

Just because something is encased in epoxy resin, doesn't mean it's gonna remain a secret for long... I dunno do you know but Nintendo tried to prevent people from clipping chips onto their DVD drives on the Wii by pouring coloured epoxy over some of the components... All it's done is made people who are determined not to buy their software think of more creative ways to break into the drive. Damn useful them heat-guns...

haha ya know...ur right, i forgot about that. I discovered how easily epoxy crumbles under heat when i was trying to get as much of the wire i could off my old servo buddy circuit! amazing.

I've done a little more research, and determined that I'm going to play with all 5 wires now and see what I come up with. I'll keep everyone posted. And Neo, let me know if you destroy a servo buddy in the name of science

chaos, were in S. Jersey are you? i live in jersey too. in fact im in trenton on McGuire AFB. we should meet up. im kinda a electronics tinker nerd. i have a feeling the white and grey wire are used as signal in and out from the servo. id like to know why they are being eliminated. my guess would be that the white wire recieves signal as well as send power to the servo motor. the grey wire should be the read signal under load to tell the ECU what the votage is as a verification to prevent the ECU from tripping the Fi light.

just my guess. the rest of the wires should be good as u set it up.

I'm actually about 45min from ft. dix. 2 of my buddies friends are stationed there. Not sure if you know them, josh dowsey and steve davenport. my buddies name is andrew hendry (he's in USMC basic, should be getting home next month)

Anyways, I was thinking the same thing. The reason they were eliminated is because I was basing this how-to off of the zx-10r. They both use the same servo motor, therefore it should work, but I have a feeling that the newgen bikes' ECU is also looking at the position of the servo, which is white and gray, so that could be the problem.

I've got no problem with meeting up name where and when.

PS...ur base is so effing confusing, i get lost almost everytime i go there!

I tried making one for my 05 zx6r using the schematics on the 10r forum. This called for eliminating two of the wires. It did not work for me. The FI light stays on the whole time. The pre-made servo buddy appears to be using all of the wires. Not sure if it really is. Anybody cut one open?

See... If you had read the last few replies, perhaps you would of learnt something and therefore wouldn't need to ask this question Einstein

p.s.... welcome to the board

Hey man I did read it. I read the thread on the 10r forums too. Nobody had posted anything for close to a week, so I thought I would ask.

Oh and I just checked the resistance of the 1 I made. It's only showing 3.87 on my meter. Since thats below what the manual calls for I'm going to try to remake it and see what happens. This time before I epoxy it into a plastic tube!

haha...nice to see someone else is trying. I've been busy lately so haven't really had the chance to play with it. i did some experimenting with other wires, still didn't work. Buck, i think you are using the wrong size resistor somewhere if you're only getting 3.87ohms...

What values are you using and are they 1/2 watt? You can either take a picture of ur circuit or tell me the colors you see on the bands. I've been getting 4.62 ohms.

The second one I tried did not appear to work. I left it plugged in and went for a ride. After awhile the FI light went off. However it would intermittently come back on for awhile then go back off. It seemed to come back on when I would open the throttle somewhat abruptly. I don't think I checked the resistance right on the first one. I didn't keep positive lead on the right wire. I would switch them around and the meter would go counting up then to 0.

the reason the meter would count up and then read 0 is because you were reading the capacitor. Basically what happens when you ohm on the negative(ground) side of the cap it will fill up, causing a read of 0 (or closed with no current). to read properly you have to read on the positive side of the cap...basically just the 2 resistors.

I have a feeling our bikes utilize all of the wires, it's like the ecu wants to see a signal from everything...im half tempted to just fork out the $$ for a servo buddy then strip it in the name of science.

Well, I decided to try this instead of paying 60$ for one. My FI light is on for about the first 2 minutes of riding and then turns off. It also comes on briefly when the bike is run over 10k rpm. other than that, seems to be working ok. I used the parts listed in the original post on the zx10 forums:

1x 220 ohm 1/2 watt resistor
1x 4.7k ohm 1/2 watt resistor
1x 470uF 16v capacitor
