I have a ZX14 2012 with a Power Commander Pod 300 Installed. I'm trying to setup the Speed selection and I'm having trouble finding the speed wire going to the ECU can someone help me out.

I think you can splice into the cable that reads from the sprocket, doesn’t have to be the ECU.

There is no "Speed Wire"

Gen2 >= 2012 doesn't use a sensor off the CS sprocket.

Speedo moved to the CANBUS system and uees the speed rings on the wheels.

I've never installed a PC Pod 300 but from what I
understand is that it plugs into the CANBUS system of the
bike and will automatically read the speed off the CANBUS system.

You should call DJ and ask them.

The POD 300 plugs into the PCV and reads whatever the PCV is plug into or tapped into.

Walked out to the '017, looked for 2 connector junction points at the sprocket cover area. One connector I know is the gear position/oil sending unit wires = 4. The other might be the speedo input. How to tell which connector? Say I pull one connector, I now see a 6 or N in the gear number box in the dash. That, or no oil light with key on-engine off. Now say I know the other might be the speedo connector. How do I tell? Ride the bike. If no speedo reading = Bingo! I now take my multimeter and find the hot wire at the main harness connector side. That's my input wire to the back of the pc with the tiny screws. I find the manual it came with, count the input holes where it calls for the speedo input on the pc. Solder the wire strands at the end of the wire, file the lead off till it fits into the hole and remember to pinch down on the lead with the screw and try to pull it out.
On the harness side of the hot wire, I take safety wire and push the wire thru the back of the connector where the rubber weatherpac is. I push that wire thru until my meter shows contact at the safety wire and hot connector prong. I goop glue the wire at the connector and plastic harness cover and let it dry overnight. I check again for wire to prong integrity. I now solder the other wire end to the safety wire. I goop over any exposed metal of the wire ends = Budaboom-Budabing.

Squids cut off/cut into-OEM wires. Meguyveers loophole with a back-probe entry when tampering with the OE's integrity.

It is my understanding CAN in simple terms means a separation of input signals. Meaning, the tone wheels are analog [many=01010110100010100] inputs. Whereas the intake vacuum sensor would be pegged as a digital [single-11111111] input at a sustained WOT. CAN separates those signals from crossing into each other's input signals and could be misread at the ECU. CAN is used on both gen harnesses.

I think this guy is asking about the auxiliary wiring required to calibrate wheel speed and gear position for data logging with the POD 300. For the Gen1, the PC5 does NOT receive a signal for gear position or wheel speed through the main wiring harness hookup. You do need to tap into the speed sensor and the gear position sensor to do each of these. For Gen2, IDK.

Sorry, I have not done this to my 08 yet so not much detailed info but this might give you a hint. Furthermore, I have the LCD, not the POD.

Steps 81-92 here:

http://zx14ninjaforum.com/messages.cfm?threadid=44AAADCF-E0E7-7BD8-FA7ACA0B7857901F

Also, the Control Center software must be used to configure the PC5 to receive wheel speed and gear position signals.

Steps 28 and 29 here.

For Gen2, IDK.

Not possible, there is no speed sensor like there was on <= 2011

Was moved to the speed rings on the front and rear wheels and
sends signals through canbus to the ECU.

There must be a sensor for the speed rings and that must have a wire. Maybe that is where you would tap in for the Gen2. The question then would be front or back wheel? I'd guess back so you could see wheel spin in data logs.

I have a feeling this guy just called DJ and got the answer. Hope he comes back to report.

Go and try to buy a speedo healer for the Gen2......

You can't they don't make one. Why, no speed sensor.

clip --- ZX-14 (2006-2011 only / 2012-up is CANBUS and non compatible) --- clip

Tapping into the CANBUS system is a lot different then
just tapping into a plan Hall effects sensor circuit.

Ahhh-- Well it is good to muse over this even if we are not 100% sure what the guy is asking about.

I got information from DJ that an aftermarket gear position indicator (like a GIPro) was sufficient for providing a signal to the PC5 for LCD data logging. I'll bet an aftermarket speed sensor would work for wheel speed since you can't get that off the OEM electronics.

Hope this guy comes back and tells us.

Three threads all the same posted eight days ago and one minute apart? No check in yet? No link, can't be a spammer. Could be a troller and a mighty good one at that!

The days of poking, prodding, super gluing into a sensor circuit
are passed. The circuits of later day are very sensitive.
Using volt/ohms meters just won't cut it. I wouldn't tap into a sensor circuit
without using a oscilloscope so I could see exactly how I was effecting
the circuit and to see if I could get signal out of the circuit without effecting the
original signal.

The best way to get speed info from the bike itself would be off the OBD port.
You would just need to capture the right data stream.

I've been wanted to mess with the OBD port for some time, but too many
projects going on.

Here's some info and good starting point.

As for tapping in, if you could just buy an aftermarket speedometer and hook up the sensor, run the wire straight to the PC5. Who cares about how the signal is effected if it's not going to a speedo anyway?

This seams to be going in several directions.

At one point I'm talking about Hall Effect sensors in general.

Here's a quick (ruff) look....

A Hall Effects type sensor creates a pulse from it's magnetic field and
and forms a wave form signal. The sensor does not emit 0's and 1's

The output signal shown in the above image does not come out
as clean as it shows. It can look something like below depending
on the signal to noise ratio, spikes, etc.

Through specific filtering you can create a clean square wave signal
for the processor to clock in and read high/low and convert to binary equivalent 0' and 1's

The issue is the filtering of the signal is specific to the sensor/circuit.
If you tap into the circuit you can change the wave form and/or add
noise into the circuit that the filtering wasn't designed for and create
false readings.

This is a very simple explanation and not the best example images and
of coarse I'm no electrical engineer, anyone feel free to jump in.
This also depends on the sensitivity of the circuit itself.
I've run into sensor circuits that where extremely
sensitive to trying to pull signals off the circuit but I think you get the idea.

That's why a oscilloscope is a good tool to have when working with sensor
circuits so you can see what's going on and that you are not interfering with
the original signal. Just tapping a wire into a sensor circuit is never a good idea,
Older sensor circuits do not seam to be as sensitive as to days circuits are, a lot
more going on.

as far as a sensor being part of the CANBUS circuit you can read CANBUS data
off the diagnosis port (OBD port)if you know the message/code id and can log it.
No need to tap into the circuit.

What's up fellows I just log back in to the sight. Its been a minute because it is frustrating that Dyno Jet don't know how to help a customer with there bike. You buy parts from them and they don't know what wires to connect too.They say do this do that not sure. Why are you promoting if you don't know what to tell us how to connect it up. If you guys get the opportunity to go to YouTube and type in Speed and Gear Calibration you can see what I am trying to do. But hope is getting weak and I'm getting tried. I don't know a lot about bikes but I will try to work on my bikes to save me money. If anyone can help me I would appreciate. You can call me also 972 523 7828 cell

There is no "speed wire" on >= 2012

Speed sensor is now part of the CANBUS system/network won't work.

It might be possible with aftermarket sensors. Apparently it will not work with the stock sensors as Piken is explaining.

If you are not getting the answers you need from DJ, get in contact with Chris Kelley at DynoJet. You will probably have to use email and ask one question at a time which will be time consuming but you should get the info. If Chris Kelley doesn't know, there is no answer. It could be that the speed and gear position inputs worked with older stock sensors but apparently not with the latest.

Piken, do you think I will be able to tap into my Gen 1's speed sensor and gear position sensor to send a signal to the bikes PC5 for data logging??

Yes, I believe so.

The speed sensor <= 2011 is not on the CANBUS. So you have a "speed wire" that
you can tap into or add a speedo healer, etc. It sends a sensor signal comparable to the above sensor that
I posted. Once on the CANBUS you have to decode the data stream / packet to get
the reading from the sensor like through the OBD port.

I'm not saying I'm any expert at this It's just how it works as far as I know.

Thanks for your help guys. If I get working I will let you know.

Yeah, thanks Piken.
