Yamaha/Moric single cylinder ecus ?? YZF R125 in mind


@Splurk: Petrik has already tried HCS12. WHat he means to say is, that his driver might be unstable at the moment. Assuming that his hardware is alright, there's an unstability in the interface. HCS12MEM and CodeWarrior are sometimes able to read the microcontroller, and sometimes not. So, he thinks trying a different set of drivers might be a good idea.


Both Petrik and Splurk:

Check these drivers:


http://forums.freescale.com/t5/OSBDM-JM60-Open-Source-BDM-for/USBDM-Version-4-Beta-JB16-JS16-JMxx-Hardware-Versions/m-p/60058


http://208.74.204.137/t5/OSBDM-JM60-Open-Source-BDM-for/USBDM-Version-3-JB16-JS16-JMxx-Hardware-Versions/td-p/55789/page/4

I just found the above while searching for drivers. It has a lot of documentation which I dont quite understand. Maybe Splurk or Petrik can understand the documentation better than me.


Also, CHECK THIS! An awesome BDM tool, open source USBDM, for just $9:

Thanks, that's interesting. I have ordered one, as I have a spare ECU at home, sleeping on my desktop. It's time to wakeup!

Would someone from USA be kind enough to arrange one for me also? They're not accepting any international orders at the moment! Would love to own it if it's to work with our ECU..

Sorry I'm in France... I don't even know if they will accept my request.

Edit: they accepted, they've sent the bdm board on friday. Now I'm waiting. I think you can also order one, they should not refuse.

I have soldered a 4.4MHz quartz on my spare ECU, now I can theorically reach 11500 rpm, but the valves are not following after 10800rpm. Cost: 0.6!
I order to get full use of the limiter removal, you have to change the valves spring with a higher K or compress them a lit bit more (on the valve seat, add a washer). As we want to hack the ECU and remove the limiter, this is good to know.

Now I'm going to open my second ECU and solder a bdm adapter.

Yes, it's been out of stock ever since! :( I'm badly waiting for them to re-stock..

Splurk, we've already discussed here about the crystal hack. But the problem is, by changing the frequency you're upsetting the data rates,etc too. Which means, there's a chance that the ECU may no longer be able to communicate with the FI Diagnostic tool,etc. All the timers will be upset. So, it's not so practical in my opinion. Atleast not for the daily user.

And, we're not hacking this ECU for the rev-limiter alone. There are so many more possibilities. Like, tuning of fuel maps(the stock map leans out as the engine revs high), quick ear shifter, and heck.. we could even add a RAM air intake! Yes, we can disconnect the lean angle sensor, and use its communication line to operate a valve, that actuates RAM air intake..so that it's operated only after reaching a certain speed or RPM. So, the possibilities are theritically endless...that's why the ECU hacking! :)

A friend is having an ECU with a different crystal, his bike is running 60 miles per day without any problem for monthes now. My idea was to quickly test this solution. As you mentionned, the Fi-Diag is not communicating anymore. But for daily use, there is no problems. But that was only for test purpose.

I know the purpose of ECU hacking. That's why I'm here, rev-limiter is not that much interesting. That's why I have a second ECU, with a BDM tool. But I enjoy testing everything whenever it's possible.
Concerning RAM air intake, studies show that it's usefull only after 106 miles per hour.
For me it would be more interesting of having a 02 sensor for correcting the map fuel. Ok first we have to get out this code from the ECU!

Edit: Ok here is the status.
I first started with CodeWarrior. Bad thing, there is no way to remove the automatic load of the program in the MCU when selecting TBDML connection. Hopefully I was not able to communicate with the MCU. Avoid CodeWarrior as much as possible, as Petrik mentionned.
I ran the self-test USBDM tool. It's finding the device, but when I want to use the "settarget" to "HCS12", the tool is telling me that this MCU is not compatible with my USBDM. This is not what is said on the website. Trying to update the firmware to the latest version returns an error, and then the firmware of my tool is dead... so I don't think this board will make us happy...
I'm trying to ressurect it, but whenever I try to program the USBDM firmware, it's failing.

Sorry, I didn't mean to be rude.. :)
Anyways, did you try using HCS12mem? There's a link somewhere here on this thread..Plus, on the website, they say this tool is fully compatible with CodeWarrior. Try using more features of it again. And also, did you try TMT's software? It's excellent, don't know if it's compatible with this BDM. And, I think we shouldn't worry much, since this is an open source tool, people will always be ready to help us. Try posting in their forums about your problem, or try speaking to the customer care directly, I'm sure we'll get a solution. As for me, I'm still waiting for the re-stock..but will take it only if you think it's useful.

Yeap I tried to use HC12MEM, but basically the DLL of the BDM dongle I have is not even able to communicate with the tool properly.
I cannot even reflash the MCU of the BDM in order to restore its firmware. It's failing every time and the device remains in ICP mode (In Chip Programming). The problem here start with the BDM board itself, it's not expected that the firmware update is failing every time.

I have to go for support now...

Finally received the KIT33812 from Freescale. That is a complete single cylinder ecu using HC9S12P128 processor assembled on a prototype board that can be used as an ecu. The ecu is called KIT33812ECUEVME and also contains all the files to reprogrami it. Together with this ecu comes KITTBDMLEVME which is a TBDML interface for HC9S12 processor family.

These were the tests done today.
- KIT33812ECUEVME was succesfully reprogrammed using KITTBDMLEVME and Codewarrior
- hcs12mem did not connect to KIT33812ECUEVME and gave similar error messages as earlier. Please note that this is the same ECU that I succesfully had reprogrammed. I tested several ecu definition files and processor speeds.

- Codewarrior was not able to connect to YZFR125 ecu using KITTBDMLEVME
- hcs12mem did not connect to YZFR125 ecu

So this boils back down to the tool issue if hcs12mem is working or not. At least now I know to have a BDM that works with a reference design.

Here is a link to the evaluation board that was used for testing the connection:

... and why am I so interested in about this freescale small engine refereice ecu ....

On one of the engine definition files the freescale directly hints a setting setting value for Yamaha C3 and when looking at the Yamaha C3 the ecu it looks very similar to what we have... so there is a small opportunity that the freescale reference desing is somehow related to yamaha/moric.

Dear guys,

I'm akri come from indonesia, east kalimantan.

I'm very lucky and interesting with your project to be hack YZF-125 ECU.
in My country the bike's name is Yamaha-Vixion and in Malaysia with name is Yamaha F-150i.

Nice to be hear your discuss about that.

thank you.....
(I'm sorry if my english not good)

@digislayer :

Could you give me some information about what tools or software must I prepare for try to remapping Yamaha/Moric single cylinder ecus ??

In My country this is amazing for remapping the ecus, but we still difficult for find something like a coldfire, f1 diagnostic tools and etc.

I'm sorry if I a lot of ask, because I'm a newbie in motorcycle


thank you for your attention



regards


Akri

I've tried all the turorials, but since the first update of the BDM board, the device is not responding anymore. It was not working at all since the begining anyway, I think mine was broken. But I give up this board, it will cost me more to send it back rather than buying a new one.
Let's try again later with another one.

Akri, read the entire thread, but the status now is:
Petrik is able to communicate with the board, but not to erase/program it
The remaining of us are trying to use BDM board.

Thanks to all, who trying to hack this ecu.

Splurk,
thanks for your attention and remain me about that.
I will to try to check and prepare anything for communicate to ecu.

Do you know, how long need for shipping the kit to my country, if I will buying the kit by online?
Where and how I can buy the kit for communicate with the ecu.....


regards,


Akri

Sorry,

Splurk I'm late for replay because now I'm in the field still working.
May be 5 days later, I'll be home and then I'll discuss with my friend (same country and my town).

thank you.


Petrik,

If you any info about the last status.....please share with us...?
thank you



regards,


Akri

Thank you splurk for your info,

Do you know about :
How much the price for the kit include cost of shipping from US to Indonesia?
And what about the kit? it was ready stock (same with which petrik use for communicate with ecu)?


thank you


akri

I got no idea, probably more than 30$ as it was the cost for shipping to France.

And I have no idea concerning the board Petric is using.

[/url]

Which file? I have had a brief look into the Freescale software, it is designed such that the hardware platform can be fairly easily changed. The reference design is quite different to the YZF ECU shown in the pics, with the reference design using a number of Freescale ICS instead of the discrete solutions that the YZF ECU appears to use.

I'm quite interested in utilising the reference design as well but porting the code to the YZF ECU would be interesting too.  Can we please move this thread elsewhere so it is easier to find?

Sorry but i have others problems to resolve first.

It looks like only a few people actually have a ECU they are willing to destroy so only a few people on the board ar able to work on this. The issue is that no dump is available yet.

I am on holidays in Thailand currently. I will try to purchase a Yamaha ECU in Bangkok while on holidays so I will have one to play with. I currently have a Honda single cylinder ecu, tried to buy a suzuki ecu but ended up with a CDI. Even after pointing out the part I wanted and the part number still got the wrong part. Never trust a goodlooking girl who speaks english in Thailand.

I may post pictures later this week of the Honda ecu.

Mikaspt, sorry to hear about your mishap.

On my side the priority is now the next racing seasons modifications to busa ecu and study if K7 gixxer can be reprogrammed. After those its time to look into this again, its my YZFR125 is my sons bike. But currently this project is waiting for a major discovery how to hack the port. There must be a way to reprogram the ecu from the harness connector as this ecu is so widely used that it would be impractical to manufacture it for each bike separately, but I dont know enought about freescale to find out a way how.

I'm supposed to be moving house and a lot of my stuff is in storage, unfortunately its all gone wrong twice so I'm still looking for a house to move to. It'll be at least a few months before I have everything back together and I can start playing with bikes again, on the plus side it'll be warmer then, we've had a lot of snow.

I will probable not be buying a bdm in thailand just an ECU. Dumping the processor is only one part of the process. I may go to the area that sells a lot of electronic equipment and see if they have a bdm but they are usually not that cheap. I usually just buy online and have it shipped to Australia.

I think the goal is to be able to flash the ecu with out using a bdm everytime. I think the ECU can be reflashed in the harness as you do not want to be replacing every ecu in all bikes if there is a bug or a issue with the mapping.

That's right, but prepare to be that need experiment for hack this ecu.

I have got a differnt BDM that has not been tried so far. I hope to have a go at getting a read in the next few days. I have only just hacked the back of the ECU. The pin spacing was not what I expected.

Okay this week i will change xtal and send ecu to a r125 rider that have a way of change fuel mix, lets see if the rpm limit is going to change to almost 12000 rpm or not.
i don't have a r125 to test so i will try to find one that understand and have a r125 so we can find a way of get rpm limit 10500rpm gone.
the valve floating is near 13000 rpm.

very useful information, our country has many R15 that got the same problem with Rev limit. I used Fi tool but it can adjust Co level only. Daytona racing CDI is used to used ignition map only like BRT from Indonesia, BRT can adjust the value of ignition map but no model for R15 while Daytona is very expensive.

After fixed Daytona whole kit to my customer bike, I compare the racing and stock camshaft and checked the CO , it is not much different so I think Daytona CDI did not adjust the fuel map.

If the R15 is similar to one of the bike I got an ecu from it has no other external memory present. The ecu has less pins than the ecu shown in the pictures but a similar processor.

YAMAHA WR250R has same ROM MC9S12T64 and same BDM port.
