How to Flash Chevrolet Cruze Simtec 76 ECU with Kess V2

Today I was flashing the engine control unit on the Chevrolet Cruze A J300 2012Y 1.8L AT.
The car arrived with errors after the service, where they changed the rear lambda, put a trick, checked the wiring, cut the cat, etc:
The owner of the car is already tired of all this, so it was decided to flash the calibration under E2.
What I actually did)) Siemens Simtec 76.1 control unit :
For the firmware, we will use the KESS V2 Master V4.036 programmer :

Launch KSuite :
Select the Chevrolet Cruze with the specified control unit:
We fall into this menu:
To begin, let’s make the identification of the ecu, choose the ID :
Kess v2 displays ecu information
HW: 10123891AM
VIN nr .:
SW ver .:
Spare: 25182010
Engine: F1G3
HW Ver .: SIMTEC76
SW upg .: J8IB20A4.DR
Now we will read the ecu, select READING :
In this case, the ecu is read ~ 5min, its correct size is 1Mb, it contains caliber. Send the file for calibration, or buy the edited firmware file. Next we will record, choose WRITING :
Then select the desired file:
We write the edited calibers:
Recording takes about 1min. Now we will remove errors that could appear during the recording process, choose TOOL :
In the new submenu, press DEL ERRORS :
We agree with all that the system offers us. We see that the task is successfully completed:
We start the car, we do not observe extra errors on the back lambda, that’s good.
All good.

Which tool to read VAG BOSCH EDC15P+ ECU on bench

Question before entering:
I have some trouble with my spare EDC15P+ ECUs.  I have now invested in a MPPS V21 because of its booting capabilities!  But No matter what i do, MPPS keeps saying “Booting of ECU failed” or it freezes during connection establishment. I have tried this om 3 different ECU’s with bad flash and 2 PC’s.
The procedure i use:
Generic -> Micro Boot -> EDC15P -> Pin 24 to ground and Power On -> Remove ground from Pin 24 -> Select ECU ID
Happens every time and it’s driving me nuts. I have bought MPPS for the sole purpose of recovering bad ECU’s, so i really hope that some of you maybe can help me with this.
Expert solutions:

Solution 1: with MPPS

With MPPS V21, you need luck. V21 maybe too new to this ecu.
Check with multimeter pin140 to pin44 and pin104 to pin24.
I bought MPPS HW12 china clone, software v16 for hardware 12. For a long time ago I had a similar problem with VW Sharan , I do not remember exactly how I was reinstall the firmware on it.  But finally it works. Here are some pictures:

Solution 2:

MPPS V13 no problem on this ecu
I try read with kess v2 and mpps v21 edc15p+ and I get error, but with mpps v13 no problem to reading this ecu on table.
So i finally got my spare ECU’s working again. I ordered a MPPS v13 ecu flasher, and that one was able to bootflash all the ECU’s.

Solution 3:

Kess v2 master read EDC15P+ on bench on issues
Testing edc15p+ of a Seat Ibiza

Solution 4: 

Fgtech Galletto V54 on bench Writing vw EDC 15 P+ no problem
VW pasat 1.9 PD writing edc 15p+ 115 mph up to 130mph and egr off.

Volvo EDC15C11 Read and Write by Kess Ktag or MPPS

Here are optional solutions of Volvo V70 EDC15C11 ECU read and write using different ECU programmers, incl. Kess V2, Ktag, MPPS cable, FgTech Galletto 4 V54.
Car: Volvo V70 D5 2004 163hp
Ecu: I think the car has either a EDC15C2 or EDC15C11 ecu. (K-suite states EDC15C2)
Option 1: You can use Fgtech Galletto V54
Rread/write work only in bootmode at this car.
volvo s60 D5 163 hp euro 3 with edc 15c11.
Option 2: Ktag can do it
You can use me 7 boot edc15 ecu
I’ve done it with many volvo edc15c11 with kess pinned from obd to Ecu and ground pin 24!
Option 3: Kess v2 makes it
Some Volvo EDC15C11 just refuses to be read with a ktag tool. KessV2 bootmode always solved me this problem – wake up error
Reasons were that my power supply was playing up so used an old atx computer supply.
I’ve managed to do it by a kess v2 as well
For those wanting to read/write and ecu containing the AM29F400, AM29F800 chip with kess v2 just follow theses steps.
Connect ecu to the appropriate pins.
Put it into boot mode by grounding pin 24.
Open ksuite and in protocol menu select boot St… Once in there select Bosch MED 7 29F400. The protocol 114 and is the same for for 29f800 as well.
Just proceed to read and write as normal.
But beware the ksuite doesn’t do checksum this way so be sure to check your files.
Hopefully this can help a few ppl
Btw, you can write this with kess. never used ktag but should be the same tbh
never used i/0 terminal.
Option 4: MPPS cable works good via boot mode
Is the ECU going into “Boot mode”? if its not going into boot mode then you have no other option but to remove the eeprom and put into an external programmer. TBH its not that bad.
Have you got MPPS? Mpps is by far the best for boot mode and recovery and will do all 29f*** series under “EDC15 generic mode” but you must be able to get ecu into boot mode.
Another important note:
To tune the EDC15c11 you only need the 512kb file!!!! Also going through generic mode on mpps, kess, ktag with edc15c11 you must make sure cheksums are done as the software will not correct them!”
Have fun!

KESS V2 5.017 Review: 100% Write Toyota Yaris 2NZ-FE 2007

Have something about KESS V2 5.017 i wanna share with all.


About my package KESS V2 v5.017:

I spent $199 on it (src: http://www.obdii365.com/wholesale/v5017-truck-car-kess-v2-ecu-tool.html)

It’s a china clone with a green board. I put it here


About KESS V2 5.017 software:


Kess 5.017 came with Ksuite 2.23 software (a CD), saying Windows XP is the best operation to run on. And i did.


I opened KSuite 2.23 (E:), ran “ksuite_222_v2” exe.

Ran the setup application

Then Next, Next… to install

I accepted Microsoft Visual C++ 2005 License Terms, and setup in English

Finished installation!


Then, i can run the software to setup ksuite language

Important!!! replaced all files in C:/Ksuite 2.23 with E:/Ksuite 2.23

Then, i installed software for USB device and checked in Computer management


Here is all i did for kess 5.017 installation.


Then i can use it for ECU tuning.


About Kess V2 V5.017 master clone tuning experience:


My car is 2007 Toyota Vitz (P9x), with ECU: 2NZ-FE


Kess V5.017 working with 2007 Toyota Vitz (P9x)



Began to write Toyota Yaris 2NZ-FE






So, Kess v2 fw 5.017 has written my Yaris 2NZ-FE successfully


Here is something i have confirmed. Maybe helpful to someone.


  1. it’s working with original database on Win7 Win8 (not only XP)
    2. Fully activated: all protocols available: EDC17 / k-line / DSG / DQ200 DQ250 DQ500 Gearbox / ST10 …., no gray buttons!!!!
  2. 3. can work with the 2016 model;
  3. i compared it with kess 4.03: kess 5.017 adds 140+ vehicle types; can support car/truck/tractor/bikes (version kess v2 v4.036 supports cars only)


It’s nice when it works.


Why should you buy KTAG 7.020 and KESS V2 together?

Here is the NEWEST & BEST ECU tuning tool bundle: Ktag 7.020 + Kess V2 5.017 + ECM TITANIUM V1.61. This kit works good at ECU tuning/programming and ECU remap.


ECU programmers for sale:

KTAG V7.02 $199 + KESS V2 V5.017 $199 + ECM TITANIUM V1.61 $22.99 = $420.99
A bundle (Ktag, Kess, ECM)= $357. $62..99 saved!


WHY you need buy Ktag + Kess + ECM together?


KESS V2 is a ECU programming tool that is perfect for OBD use, while KTag is perfect for Jtag, BDM and all the Boot application (tricore and ST10).

With KESS V2 you programming directly through the OBD port of the vehicle, while with Ktag you need to take apart the ECU and open it, after you can make the read/write operation.

Many ECU has the advantage that can be read and write from OBD port (so KESS V2 is perfect), but there are lot ECU that need to disassemble from the car and open and this is the case for all the ECU that need to be programmed with Jtag, BDM and Boot protocols, so KTAG is needed.


WHY you should buy the NEWEST bundle: Ktag 7.020 + Kess V2 5.017?


KTAG firmware 7.020:

works better, faster and more stable than old versions

  1. adds 100+ ECU types & supports new car models e.g. Toyota 76FXXX, PSA 17.4.4, Ford E83, VW 17.5.5 (1766), Mercedes-Benz 276 ECU, Toyota 76F, etc.
  2. more languages available English, Italian, Portuguese, French, Deutsch, Spanish)
  3. better wiring description (in words not pictures).


Kess v2 firmware 5.017:

Compared to KESS V4.036, the KESS 5.017 has been improved a lot:

  1. 100% working
    2. No tokens limited
    3. with original database
    4. Windows 7 & Windows 8 supporting, not only Windows XP
    5. supports more cars & bikes & trucks unlimited tokens, fully activated

So, with Ktag v7.020 + Kess V2 v5.017, you can read and write ECU without token limitation for OBD, Jtag, BDM and Boot use for the new models and protocols. But it cannot be used for Tricore; you need go to MPPS V21 cables.


WHY you need ECM TITANIUM V1.61?


Crack, No need activation and key


ECM TITANIUM V1.61 crack allows you to accurately and easily, autonomous and completely safe to interpret the files on Windows XP or Windows 7 in Italian/ English/ Portuguese/ German/ French/ Spanish, that are contained inside the motor controller. Through the use of Driver which true “contents” pose for reading the files contained in the control units, you can easily find the data stored in the file maps and the main rev limiter to increase the engine power, or simply the consumer to optimize.


18475 Driver:

The outstanding component of this product are its drivers the latest Generation. They offer a well-structured and functional powerful interface to create and manage projects in terms of the machined in ECM Titanium files. After the file contained in the memory of the control unit has been read, it is enough to load it. Then the software starts a search to check the presence of compatible drivers both in our personal as well as in the online database. Thanks to the studies of our developers, allows the software about to act directly on the main areas: control of air-fuel ratio, engine torque, injection system, Rail, Turbo and many other options are available.


Checksum work 100% fine:

It is a bit sequence that is used for checking the completeness of the data. Every time you interact with a single bit, interpreted and automatically corrects ECM Titanium the control sequence. Therefore, a successful course is guaranteed, no matter whether you work in real time or whether you need to send a file to your slave.


Ktag 7.020 Kess 5.017 review:


Ktag v7.020 review:


I try with edc16c31 smart 451, read write in bdm ok with ktag, read write ok in obd with kess.


I tested with a lot of edc17 in these day and read and write without problem.


I made a video with a edc17c50 bmw 120d f21 with gpt, read and write ok.
I have a fiat edc17c69 virgin (without software inside), this I can’t read.


My Ktag 7.020 is able to read and write EDC17C69


7.020 version runs faster and more stable.


Ktag 7.02 good working. no problem.


Ktag master 7.020 displays diagrams via words, not pictures. It’s better to understand0


I tried to read Bosch edc17c69 gpt Fiat 500X and not working, with ktag ori read and write ok.


I read a lot of edc17 and few edc17 with gpt and all read and write ok maybe there is a bug in sw/fw from alientech.
virtual reading is = servidor ALIen.
virtual reading id ecu , and download firmware.
Not real soft.
uds vag =


I compared 7.020 with my old 7.003. KTAG fw 7.020 adds 100+ ECU types and supports new car models e.g. Toyota 76FXXX, PSA 17.4.4, Ford E83, VW 17.5.5 (1766), Mercedes-Benz 276 ECU, Toyota 76F, etc. It should be a good budget i think.


The clone Ktag 7.020 can read my 2013 Opel Insignia EDC17C59
