Kess clone write to dcm3.7 error

[nick93]

Hi, I just bought a kess clone 5.017 (red pcb) and had sucesfully read (backup) my original file from obd port.
When I try to write anything (obd port), even the original file, the data led flashes for a few seconds and then I get the error " an error occurred during the writing" at 0%


My setup:
KSuite_2.23_NO-CHECKSUM-CKS_Disabled
i20 2013 crdi 1.1 dcm3.7
HW: U700B120_DELIV_1
SW: 7H77_PBAA01_D12

is there any solution? other portocol? maybe alter firmware to sd card? faulty cable? try other KSuite ? other laptop ?

Thaaaaaaaaaaanks

kess will not let you flash this ecu..... open ecu and read with ktag... clone works with no problem... you have to solder some bridges.. will post a picture of the diagram later.

Thaaaanks, I have just ordered a clone ktag. Any pictures-help will be much appreciated.

Hello
PCMFlash can read/write this one. Module 54 i think. Also, maybe KTAG EU clone but not sure. Otherwise only original ktag, kess etc..

did you have good voltage during write? I have seen clons doing wierd stuff if voltage fluctuate too much or low under 12,5 V.
Put the car on charger and it shud work, if read was good write shod not be a problem.

Car is running after that? You didn't brick the ECU?

I have ordered this ktag https://www.aliexpress.com/item/4000085836501.html
Where can I find the EU? Is it possible to rework my clone to work as genuine and make the flash?

also tried with voltage >13 get the same error and then the protocol doesnt support this ECU

Car is running fine. I think that the write process didnt start at all. it stays at 0% and the led blinks for 5sec and then error.

Clone will never work as OEM so you must be really careful if you're using clone tools. There are a lot of cases of bricking ecu's...

[heteromies]

Kess 5.030 support many DCM3.7 OBD.

[Smart66]

Although kess works fine with many ECU's, there isn't any guarantee that it will always work well...

[nick93]

So clone Ktag (red) V7.020 has any chance to flash this ecu ?

[br556hre]

I checked last night with ksuite 2.80 updates on 7.020 red eu clone ksuite 2.25 knows more different DCM3.7 versions..
I'v been looking for info about antara 135kW and now its new (before it was same protocol for all antara dcm3.7, now it has new protocol 520 i think..)

might be worth trying..

[nick93]

Do you mean I should try the Antara protocol?

[br556hre]

I used 2.80 kSuite recently to read DCM3.7AP as Opel/GM Antara 135kW and it read it correctly even it throw crc error after reading.. I did not try write it over OBD until I get full backup with KTAG.

kSuite for KESSV2 has at least two protocols for OBD and few more for KTAG. There is one new protocol for 135kW version, cant remember protocol number (610 or 520 or something like that).

When you open it (DCM3.7AP) versions might look different, and rainbow cables need different connection order than older versions. You have it in KTAG help.

[nick93]

Ok, I will give it a try with different protocols.


Anyone have tried or recommend for this ecu
ECUF (Alex flasher) with clone Tactrix ?
