CAN BUS analyzer
has anyone been able to read the messages on the can bus between the ECU and the guages ? I am try to log info using a Microchip CanBus Analyzer to monitor but it is not recognizing any data.
any electornic wizards out there ?

I'm just curious Roy..why?
Do the gauges get a lot of useful information?

it would be the easiest way to datalog all of the engine sensors , error codes, and maybe even to write info to the ECU . vehicle speed is transmitted from the gauges back to the ECU , and who know what else it is doing without monitoring.
so why wouldn't you want do that ?

i'm not familiar with that tool but i would think you have to have an interface for the 14 and the software to decode what you are looking at

I think I can reverse engineer the messages, but right now I am having problems getting the CanBus interface to recognize the framing .....
still looking for someone who has CanBus experience

I have the analyzer reading and logging data off of the canbus !!!
now the real work can begin :-)

right now I am just using a CanBus Analyzer hooked up thru the USB port on my laptop and logging thru that. There are plent of data loggers available to plug into a cars OBDII port but I wasn't sure that kawasaki was using standard definitions. I have rpm fuel usage and water temp figured out so far .

I found this app for Garmin Nuvi ---- just plug in a bluetooth device into the diagnostic port and use the garmin to display engine info .... Just imaging how this will change they way we see and log vehicle data .... loggers should be very cheap in the future
some info at https://buy.garmin.com/shop/shop.do?pID=38354&ra=true#featureTab
since the new PCV has a can bus , you may be able to log data off of that also . I havent tried to monitor that yet , but at least the AFR gets sent to the PCV over the canbus.

We have a diagnostic port? Where the hell is this?

there is a diagnostic port next to the ECU . but that is not what I was refering to with the garmin. Cars have a diagnostic port for ODBII , and use CanBus to communicate to the ECU. that is what the garmin device uses to get info and display on their screen.
the ZX14 has a canbus between the ECU and the gauges. I tapped directly into that. I looked at the diagnostic port but i ws not able to determine if it was canbus. I need to put a scope on it. if it is , that may make it easier to connect to.
I have not tried to send a request to the ECU yet, I have just been monitoring the data going to the gauges.

This is really interesting stuff. I wonder why it has not been exploited in the past? Seems like a great combination with ecu reflashing/logging. Great job Roy!

I was able to monitor the afr from the autotune /PCV. it looks like it is sending over 100 samples/second. There is no data being sent by the PCV so no throttle position , duty cycle, or rpm.
but you should be able to use the autotune as a stand alone afr datalogger .

I havent done much more. I think now I can either replace the zx14 gauges with with a custom LCD or use the stock gauges with the Megasquirt3 ECU. it has CanBus on it also .
What I cant do is use the autotune wideband O2 sensor with the stock gauges. Autotune is transmitting at 1 Mbs and the gauges/stock ecu is at 500kbs.
so maybe the best solution would be to use the megasquirt3, autotune, and custom LCD connected by can. You would be able to look at the datalogs right on the bike .

Roy,
if you get this figured out, I'll pay you!
Its out of my league electronically, and i have no desire or time to learn it all.
kudo's, keep up the good work. 
I am losing faith in the hacked ecu development

How did you connect the Microchip CanBus Analyzer? Did you connect the CAN BUS Low and High only? I'm interested in doing the same for my Concours 14.
If that works, then it should be possible to tap into the CAN BUS Low and High from the feed into the display.

sorry for resurecting an old thread, but this is really interesting.
I am trying to get traction control working on my zx14 racecar and would really appreciate the canbus ID and any other information about rpm?
usual coils and injector feeds havent worked and they want me to use the canbus but dont have the ids etc.
Any info would be much appreciated.
Cheers
Paul

Is this thread still open ?
for the AT200 on my ZX14 I scanned 2 IDs.
ID:218109995 = Autotune
ID:201330954 = PC5
My Problem is to interpret the autotune data. I´d like to get the a/f ratio from it.
Roy wrote he was able to read the a/f ratio from the autotune.
Does somebody know how to calculate the ratio from the data ?

Hi Holger
Trying to keep this alive 
What information can you share? What bit rate did you get a response from? I have tried. 250mbit, 500 and 1gig with no success 
Cheers

Hi Paul,
the bit rate is 1 mbit! I can read the data :-) The message 21810995 contents 8 byte.
Byte 1 = afr, Byte 2= lean / rich related to afr 14.7 , Byte 7 = correction factor.
The other bytes are not used for afr.
If Byte2 = 3 , Byte1 represents afr 10-14,7 (rich)
If Byte2 = 4 , Byte1 represents afr 14.7-18 (lean)
I hope that will help you.
Cheers
Holger

sorry - forgot to write that I used the can bus of the PC5 / Autotune Module.
The can bus of the ZX14 runs 500 kbit.

Hi Holger
I tried 500kb but I got no data as I don't have any clocks. I am liaising with a company to try and get a clean rpm signal working for a traction control. They assured me that their box would complete the circuit but obviously it does not. I could use my pc3 but don't know which wires would be can hi or low and you have pc5.
For completing the circuit without the clocks I was told that canbus always uses 120ohmn? Maybe worth a try?
If I find out anything I will post it here.
Good luck and thanks for replying.

Hi Paul,
do you need RPM or speed-signal ? The PC3 has NO can bus.
You have to terminate the end of the can bus with 120ohm between CANH and CANL. But I don´t
think that this is the reason for your problem. Without 120ohm you should get data too.
The CAN wires go from the ECU to the gauge panel. Look at the gauge-panel connector for the
gray/blue and light blue wire. These wires are the twisted pair wires CANH and CANL (pin 17 + 18 at the connector).
Cheers
Holger
