How to communicate with ECUs?

michalmikolajczyk commented 6 years ago

The purpose of this discussion is to find the optimal, generic interface to ECUs.

Reading into ECU tuning, I could not find any generic ECU open-source hardware or software, until I stumbled on this awesome piece of software http://www.tuneecu.com/ (don’t be tricked by the funny looking website, the community states it's legit.)

That software is not compatible with KTM dirtbikes though. A user on another forum noted, that official KTM software for ECU tuning, can be downloaded for free, but they charge $500 for the cable. The OBD connector is CAN-bus, while the tuneECU supports the KTM Duke 690 and 990 motorcycles, which use K-Line OBD. Here is the link to the forum: http://ecuhacking.activeboard.com/t49773328/interfacing-to-ktm-keihin-ecu-canbus/

Obviously, it would be terrific for us to be able to connect an IoT device directly to the ECU. There are cables for that, e.g. https://www.powercellperformance.com/shop/tuneecu-programing-cables/ IMHO if we could skip the piggyback hardware in favor of software, it will get us much closer to our goal. One way to do this, would be to install tuneECU on a Raspberry Pi, solutions for that were found after a quick google.

Questions:

any chance of creating a DIY CAN-bus connector?
how do we interact with tuneECU running on the Raspberry Pi, connected to the motorcycle?
any other thoughts?

You can order Can2Usb cable for 25$: https://m.aliexpress.com/s/item/32611523816.html?spm=a2g0n.search-cache.0.0.34656344ZS6HyG#autostay

With raspberry we need to use a module costs 1.51$ over SPI: https://m.aliexpress.com/s/item/32647462532.html?spm=a2g0n.search-cache.0.0.4b2e10c7PxJioy#autostay

Also some cables :)

michalmikolajczyk commented 6 years ago

@decaun that is quite cool.

If I understand correctly, we can basically connect to the dirtbikes via a Raspberry Pi. And to connect to a whole other set of machines, we could just use tuneECU.

So what remains is the software to actually communicate with the ECU.

Here is an interesting discussion on the subject: https://thumpertalk.com/forums/topic/1126740-ktms-ust-or-user-tool-must-read/ They mention the map files, which are *.ksd

And here is the Windows program to use with the UST – User Setting Tool (which costs like $500): http://www.ktm.com/us/service/maintenance/ So the purpose of those devices (hardware+software) is to read data from the ECU, and overwrite the fuel and ignition maps. Just what we need.

I wonder if the CAN2USB cable will allow us to connect? :) I guess if we get any communication from the ECU, we could try to reverse engineer the protocol, similar to what Sergey Pisarenko did here http://pisarenko.net/blog/2017/04/16/internet-connected-motorcycle-project/ with the Power Commander software.

Does that make sense to you?

My main concern is that, I would rather have the project focused on common solutions, rather then interfaces for particular machines. We need the prototypes, but how can we generalize the solution, and have as little hardware dependencies as possible?

decaun commented 6 years ago

@michalmikolajczyk well it depends on module we use, it can be receiver, transmitter or both depending on a chip it use. Tune ECU uses both rx/tx at can bus.

As far as i read Sergey Pisarenko already had usb connection at his bike via fuel injection module. If you have such device already it is pretty smart to use MQTT as him.

Can bus is asynchronius protocol without any clock. There is sync period between machines to decide baud rate. Maximum transmission speed is 1Mbps(16MHz).

As in http://codeandlife.com/2012/07/03/benchmarking-raspberry-pi-gpio-speed/ we can use pwm to replicate can bus at GPIO ports but with lower speeds. Speed definitely depends on language we use as you can see( only Native C is at required MHz levels).

It also makes interacting with ECU a bit dangerous on the go. If you change fuel amount on the go that might cause engine to stop instantly and someone can crash.

It is possible to replicate can bus protocol with lower speeds. We just need to implement existing protocol.

Still my concern is having less data speed and energy efficiency since we will use cpu power on raspberry by increasing development time. I dont think it just worths to code it than using a cheap dedicated solution.

I used can2usb for a car to increase fuel efficiency before, its not that easy to tune it even you have expensive hw+sw. Especially on the go it is pretty dangerous. For me safest use case is to just monitor.

michalmikolajczyk commented 6 years ago

@decaun that is great insight!

communication with ECU I am not sure if I understand this correctly though. I was most worried about 1. establishing communication with the ECU and 2. understanding the protocol and messages.

CAN-bus interface Using GPIO ports to replicate can bus sounds awesome. Do you think we need the full app to use C, or just the GPIO CAN-bus replica driver?

safety we definitely need to restrict tx access, while the machine is operating.

dedicated solutions I did not quite understand that part. I am all in for quality. Our aim is to build a performant platform. I don't mind deciding to develop less, but I would rather not compromise on the performance of our product. We can rely on other solutions, as long as the license allows us to. We should make them options, if our end users would need to pay for that. Please let me know what you had in mind.

RX / TX safety I hear you. Let's keep in mind, that we are not making an end product, but a toolset / framework / platform. We can let our user – the engineer – take care of the particular safety and security precautions, specific to their application. What do you think?

question are you sure that tuneECU uses CAN-bus? I thought they only used K-line, and I did not understand why open-source CAN-bus solutions were not available

decaun commented 6 years ago

@michalmikolajczyk

I suppose TuneECU uses more than one protocol regards to bike ECU. Please check: https://en.wikipedia.org/wiki/On-board_diagnostics#OBD-II

It goes like; SAE J1850 PWM SAE J1850 VPW ISO 9141-2 ISO 14230-4 ISO 15765-4 CAN SAE J1939

For raspberry it is pretty easy to handle ISO 15765-4 CAN at first glance. Because GPIO pins are digital and at 3.3V with max preferred 16mA ratings, specialized hw could be necessary for each other protocol(since they are rated at 5-12V at unknown currents depends on bikes battery internal resistance etc.).

Challange is not hard if you consider to apply it to support only single bus interface. But if you are willing to support all those protocols above, it is rather complex.

After some research i found an open source hw+sw designed exactly for it already: https://hackaday.com/tag/iso-9141-2/ Instead of arm we can rewrite source code and run it on raspberry. We can use multiple GPIO pins to drain less current from each and use minimum hardware implementation.

There is also pyobd http://www.instructables.com/id/OBD-Pi/ Im not sure if you can send data to ECU with pyobd since its meant to monitor it.

I think its not really necessary to have high data speed to communicate with ecu but drivers are written already at C++ why not take advantage of it.

Depending on your bike, you already have we can pick one of those protocols and start to develop hw+driver. Than we can add support to other protocols exists.

Last but not least it is going to be even simpler to just monitor ECU at hw side(possible without any special IC). So we can start from monitoring of a selected protocol. With only voltage regulator, simple transistor and few passive elements we can do it as done in here: http://www.instructables.com/id/Low-Cost-OBD2-Communications-on-K-line-ISO-9141-2-/

michalmikolajczyk commented 6 years ago

@decaun thank you for this. I believe that our Alpha, which is the first prototype, is actually read only in terms of the ECU. So let's just do this, then.

I think it would be great if we would provide at least one end-to-end path, basically supporting at least one bus interface. We would need to make that driver modular, so that it could be replaced by another one, when it is prepared. I understand that because of the voltage differences, other devices would be needed.

The bike that I have, which has the most sophisticated ECU, is KTM SX-F 250 Factory Edition, Model Year 2017. I can't seem to find which protocol that one uses, but I'll drop by the garage and check on the device, perhaps there is some more info. The other bikes have carburetors, and not EFIs. We also have access to the same bike as Sergey Pisarenko, though he used the piggyback Power Commander hardware.

serega-174 commented 5 years ago

Hello, are there any advances on this project, this topic is also of interest.

michalmikolajczyk commented 5 years ago

@serega-174 not really, but it would be nice to take up development on this again, if there's an actual need for it. Would you like to share what you are working on? Perhaps we can help.

serega-174 commented 5 years ago

There are no specific developments. but it is possible to read the fully binary firmware file. On the thematic forums there is an assumption that a simple OBD2 cable will not be able to connect. It seems like the UST cable sends a request to the ECU, and he sends him a response with a certain signal. But if you know what this request is, I think that you can reprogram the OBD2 chip or something like that

michalmikolajczyk commented 5 years ago

In the machines, that we worked with (enduro bikes, e.g. KTM 250 SX-F 2018), there was no OBD2 output :/

One of the assumptions we took, was that we would not be able to develop a standard interface solution, that would work across all motorcycles, because the motorbikes bring different hardware.

@serega-174 have you seen http://www.tuneecu.com/ ?

serega-174 commented 5 years ago

the usual OBD2 representation is missing, but the motorcycle has its own 6-pin diagnostic connector. And the computer has a CAN Bus output, since the UST is able to read sensors in real time

michalmikolajczyk commented 5 years ago

Agreed, that’s the path we aimed at

I did a little work on communicating with KTM dirt bike ecu's. A challenge code is sent to the ecu and and it responds with a hex value. You must do a calculation on the hex value and send it to the ecu within a certain time limit. If correct, the communication line will open. I have some of the specifics if anyone is interested.

michalmikolajczyk commented 5 years ago

@dyno-dave thanks for letting us know! It sounds interesting. Did you communicate with the ECU, while it was actively connected to a running engine?

Essentially, we would like to get live data from the engine.

dyno-dave commented 5 years ago

There is an android phone app "Ecu Sensors" that works on KTM's. A bluetooth OBDII "Vgate" module that works to collect data with a custom wiring connector.

@dyno-dave Could you please give me the wiring of you diy adaptor cable between 6pin diag ktm connector and the odb interface you use. I try to make my own but no connection success between my elm327 wifi adaptor and my ktm 350 exc-f ECU.

Hi there, there is an equivalent of this app on iso?

I'm looking for diag my ktm 350 exc-f with diy wire with a ELM327 interface, connections are good but nothing appends when smartapp try to connect through elm327 on the ECU.

i'm try this with 5 apps but no result. But i'm sure it's possible as you can see here

canbusobd2 commented 4 years ago

hi, sorry my english! I am from Brazil. (help google translate). - I want to develop connection to ktm exc 350 in OBD2. @dyno-dave A challenge code is sent to the ecu and and it responds with a hex value. You must do a calculation on the hex value and send it to the ecu within a certain time limit. (yes, ktm super adventure CAN BUS identical ktm offroad, for connect uses BUS CONTROLLER CAN) The CAN bus system is an intelligent data-bus and doesn't have fuses. If the system detects a higher level of current being drawn on a circuit due to an accessory connected to it, it will simply switch that circuit off. It puts an error message on your dash. That error message is basically telling you to go and make the local dealer a bit richer. Plus, your accessory still won't work!

I am sure you will be able to access...

Jacques-BAHADORI commented 2 years ago

Hi everybody,

I raise the subject because I have just recovered a KTM Freeride 350 from 2015 with a power failure ... And with an ELM327 Bluetooth adapter, and an ODB2 cable to the KTM 6-pin connector (I checked the wiring), I can't connect to the ECU. However, I tried, by energizing the circuit (by forcing the main relay with a shunt) several times with Torque, Car scanner, and TuneECU, without success.

On this motorcycle, the ECU is new (KTM invoice April 2022) and it has never worked. I think there was never a map loaded inside and there apparently isn't one by default... So I would like to connect to the ECU and try to load a MAP. Does anyone have any information on this?

In addition, I have an initial formation in electronics and I develop C programs from time to time. So, I can help if necessary...

Thank you and good day.

Best regards.

Jacques

Hi Dave,

Thanks for your reply. I hope I have the right Dyno-Dave. I was searching for some KTM ECU information and ran across a post of yours where the discussion was how to connect to a pre-2017 KTM motocross ECU. I have a 2014 KTM 500 EXC and have tried everything to connect to the OBD2 port(s). K-Line and CAN. You post suggested that KTM has a secret handshake where a token is passed, processed (calculated) and returned in order to make the connection,

Does this sound familiar? If so, I'd really appreciate hearing more about the process.

Best regards, Dan

Thanks for the reply. My initial goal is to read ECU parameters (RPM, Coolant temp, etc). I’m working with an OBD2 interface and will be writing my own program to read and display these parameters. The 2017 and newer KTM500 ECU’s can be read without any special commands, but the pre-2017 cannot.It sounds like the password may be needed to alter the ECU map data?

For pre 2017 ktm excf/sxf the ecu has a 128kb file

MCU is similar to M16C

Password for these ecu's i believe is 12 26 56 99 84 F3 F1 (ill have to go back through my files to double check)

alientech kess and piasini tools can read/write these ecu's as well as the 2017+ ecu's which have a 1028kb file

Hi Dan. That computer acts completely dead. I need to pull the hard drives and see if I can recover them. Right now I'm in Yellowstone for a couple of weeks on vacation.

Hi Dave,Very sorry to catch you on your vacation. Yellowstone is a beautiful place. We were there several years ago and really enjoyed the whole area. Maybe we can talk more once you’ve had a chance to take a look at your laptop.Take card and enjoy your vacation!DanOn Jul 13, 2023, at 8:53 AM, dyno-dave @.> wrote: Hi Dan.
