someone had tryed ELS27 with Megane 4?

[igno77]

Hi to all, I've seen in last version of ddt4all the new icon of ELS27. After a quick reserch of information I know that this interface is better than ELM (faster, stable and use Mcan and Lcan at the same time) but....we need to modify some wiring for use it with a Megane 4? It seems this interface born for Ford and Mazda cars, not for Renault. On a russian website there is a modification of the els27 but no one have had success with the connection. Do you have more info? What kind of chip we must have insiede? Thanks

[KarelSvo]

You only must to modify the ELS27 if you want to use the media can bus. https://a.d-cd.net/40c326ds-960.jpg The second can bus input must be diverted from Ford to Renault media pin. Simply get yourself an experience with els27 from aliexpress from 13 euro. Please your note, obdlink interface and els are preset to baudrate 115200. If firmware is not up-to-date then just update to scantool.net. I must to use windows 10 for update ELS.

Check photo. Description says 3-12 11-13: wrong, and photo shows 6-13, 12-14: wrong because you connect canbus and mm canbus into the car obd, dangerous!).

[premultiply]

No. "Normal" CAN-Bus is on 6+14 (unmodified). Only the second independant CAN-Interface needs to be briged to Renault MM-CAN on 12+13. Ford-Pins 3+11 does not have any connection on Renault vehicle OBD port so there is no need to remove or disconnect them on ELS27. Just wire these two connectors and you can use it on Ford and Renault vehicles.

[pakoto]

Sorry, i mean that zmiterm bridge 6-13 and 12-14 and use it out the car. See green red cables in the photo and compare position with generic OBD pinout photo. If you connect els27 like this, you shortcircuit canbus and mm canbus into the car.

[ohayyam]

I tried many combinations but no success. Even i disconnect obd socket side and main board connections and made many more combinations according to ford and renault pin out diagrams but all fail. I never read succesfull story. does really anyone use els27 with any renault ? I already asked to zmiterm on drive2.ru no answer. I believe els27 may fake ??? I contact russian seller of original els27 he said 75 usd but he did not know about cable modification for renault. He said original els27 will work with renault. I am not sure and waiting to read success story with els27 and renault.

[pakoto]

Clone els27 works with canbus, but NO with MM canbus. Tested by me with cedric. We need to know how ELS27 switch between canbus/mmcanbus (soft-controlled?)

[premultiply]

Simple second virtual COM on USB?

[ohayyam]

I already mail latest ddt4all v.3.4.5 program with mar2018 database to cedric to check ;) download link on drive2.ru site by zmiterm.

My els27 may damage during combination try :)) never connected or it was fake because i tried it without cable mod. It did not work for me.

@cedricp This looks like the protocol description to change the CAN interface for MM-CAN access: https://www.scantool.net/downloads/118/mx_protocol_commands.pdf You have to select a "MS-CAN" preset first an then adjust the baud rate to 500000.

[cedricp]

I saw that, but I don't have the hardware to test it yet.

[premultiply]

I have one here. How can I assist you?

[cedricp]

I created an els27 branch, you can try it... (a dropdown box has beed added in the toolbar to select CAN line)

[premultiply]

First try run (without connected to car X10 ZOE) with els27 branch:

[cedricp]

This error is not related to els27 work, which ECU are you trying to connect ?

[cedricp]

Just committed a fix for this kind of problem.

[premultiply]

Ok, did a test on my car (ZOE) now but switching to "MediumSpeed CAN" does not change anything. All communcation stays on HS-CAN.

Switched to "MediumSpeed CAN" after startup, selected my vehicle from list and pressed scan. All ECUs from HS-CAN where found but nothing from MM-CAN (Navigation/MFD, ...) was found.

[cedricp]

Did you rewire the MS-CAN lines on the OBD connector ? AFAIK, it's not connected to the good pins.

[cedricp]

Just fixed an issue with MS-CAN scan, sorry, can you retry ?

[premultiply]

Yes of course it's rewired. Yep, I will try again in a few minutes.

[premultiply]

Sorry, still only ECUs from HS-CAN. And manual MFD selection still does not get any data.

And many

[premultiply]

There are some more command descriptions in https://www.scantool.net/scantool/downloads/234/stn1100-frpm-preliminary.pdf which are removed from later versions of the documentation.

[cedricp]

That's weird, can you send me your elm log over ?

[cedricp]

You can also try to add a line at the end : elm.py 1192

        if canline == 0:
            if 'brp' in ecu.keys() and ecu['brp'] == "1":  # I suppose that brp=1 means 250kBps CAN
                self.cmd("AT SP 8")
            else:
                self.cmd("AT SP 6")
        else:
            self.cmd("STP 53")
            self.cmd("STPBR 250000") # this line

[premultiply]

No problem. Sent you the log by mail. But there is no STP command inside at all :-(

[cedricp]

Thanks, Have you dowloaded the els27 branch and selected ELS27 dongle at startup ? https://github.com/cedricp/ddt4all/archive/els27.zip

[premultiply]

Mmmmh. I downloaded the changed files only. Maybe I've forgotten something... I will try with full els27.zip again.

[premultiply]

Dry-run els27.zip without car connected still does show any STP commands in log.

[cedricp]

That is really strange... I checked the code several times...

[cedricp]

Ok, just found and fixed the problem... You can retry if you have time

[premultiply]

After several hours of testing I think all ST commands are sent out as raw data because they are filtered https://github.com/cedricp/ddt4all/blob/7b28b65f613559ed1780ed2eb60af8d0cb7f244b/elm.py#L737 so the never reach the ELS27. This is why they never show up in any log...

[cedricp]

Well spotted ! I fixed that issue

[pakoto]

works multimedia canbus using bridges or still pending tests?

[cedricp]

Still waiting for last commit testing ... (els27 branch)

[premultiply]

Software side seems to be ok now. But using the modified els27 on the car disturbed and crashed my radio ECU on MM-CAN. Had to pull the fuse to make it work again.

I am not able to verify that the modified hardware does what it should do.

[pakoto]

ford switch canhigh 6-3 and canlow 14-11: 3 and 11 are mm canbus. renault switch CH 6-13 and CL 14-12: 13 and 12 are mm canbus.

For conversion i think you need to connect mm CH 3-13 and mm CL 11-12. Other combinations connect mm ford canhigh with mm renault canlow and viceversa (3-12 11-13), or worse shortcircuit canbus with mm canbus into car´s OBD (6-13 14-12).

IMHO zmiterm instructions are wrong.

[premultiply]

Yes it seems you are right. The polarity is wrong. I have to change it on my ELS27.

[pakoto]

Remember that obd pinout front view images from internet are mirrored with els27 front view.

I check with multimeter pins using this ELS27 front view

\ .. 8 .. 7 . 6 . 5 . 4 . 3 . 2 . 1 . / . \ 16 15 14 13 12 .11. 10 .9 /

[premultiply]

The pin numbers are always the same for rear or front view ;-)

[pakoto]

@premultiply i need your help with off-topic if you are creator of ZOEdisplay: We are trying to add DPF soot level into dacia-renault DCIs using arduino. ddt2000 database obtain it using:

Send 22242C Receive 62242C0000 Start byte: 4 Bits: 16 Unit: gr Value: (AX+B)/C A=1 B=0 C=100

Do you know how to translate to arduino code using mcp2515 module? need to ask every x secs to ecu?

[premultiply]

@pakoto I don't know how to poll data from ECUs. Never thought about that. All I need to do for ZOEdisplay is listen to the bus.

[pakoto]

i don´t know how it works. When we connect to motor ecu using ddt4all, we can get too much sensor info than using stardard tools like android torque. We are trying to take some parameters and send to arduino lcd.

[cedricp]

It's because each ECM (engine control module) CAN ISO_TP frames are differents. This is why you need an engineer tool like DDT4all to get them. Select an ECU and look at request and data tabs in edition mode to know how frames are built.

[cedricp]

I started a project for Arduino UNO with MCP2515 here : https://gitlab.com/DrQuark/x84_can There are ISO_TP and CAN_RAW sources examples.

[cedricp]

Send 22242C
Receive 62242C0000
Start byte: 4
Bits: 16
Unit: gr

as the wanted value starts at byte 4 (index 3) and it's 16 bits wide (2 bytes) :

char receiv_buffer[] = {0x62, 0x24, 0x2C, 00, 00}; short my_value = (receiv_buffer[3] << 8) | receiv_buffer[4]; float final_value = (float)my_value / 100.f;

should be good

[premultiply]

New modification 3->13 and 11->12. Only one wire needed ;-)

[pakoto]

Yes. I have same mod. Works?

[premultiply]

Yes, hardware does work now! But the ddt4all part is not working correctly.

First problem was: MM-CAN on my ZOE car is 500 kbd not 250 kbd. I fixed it manually in code ("ST PBR 500000") 2nd unsolved problem: But even with that modification only parts of the ECU data is retrieved by ELS27 compared to an modified ELM327 on MM-CAN. But my ELS27 STN117 has FW 3.3.1 and I am not able to update it to lastest FW 4.2.4 (https://www.scantool.net/downloads/updates/stn1170/).

[pakoto]

i can´t update my fw either. Aliexpress ELS27 clone i suppose.

I´ll test with my dacia dokker connecting to medianav and post results.

[pakoto]

minor issue: elm benchmark don´t work with this branch.
