Ktag firmware 7.026 vs Ktag firmware 7.020

ECU programmers: Ktag 7.026 vs Ktag 7.020, what’s the difference and which is better?


Ktag 7.026 vs Ktag 7.020 clone:


Ktag firmware 7.026 have MCU for change

Ktag firmware 7.020 not reset CFG


Ktag 7.026 TOKENS 30 in 1 MCU

Ktag 7.020 UNLIMITED

So, Ktag 7.020 should be better for ECU programming.


(09/01/2017) Ktag 7.020 programmer 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.


  1. more languages available English, Italian, Portuguese, French, Deutsch, Spanish)


  1. better wiring description (in words not pictures).

Ktag v7.020 review:


Ktag work very well!

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

Tested 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.

In these day I must read a Toyota with nec, when I read post results.

Ktag haven’t token, I read more than 30 ecu and work the same.


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 7.020is 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.

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 canreadmy 2013 Opel Insignia EDC17C59


I’ve got two versions of ktag 7.020, one with green PCB and the other with blue PCB. No much difference when using both.

Kess V2 5.017 No Wake Up Error

Usually, you have Wake Up Error with old Kess V2, esp. Kess firmware 3.099. But now, new kess v2 programmers hardly ever pop up “Wake Up Error” when reading kess software number.


Kess v2 without Wake Up Error:

Kess v2 5.017 (so far, no)


Kess with Wake Up Error:

Kess v2 4.036 (sometimes)

Kess with Wake Up Error:



Here is an awesome write-up of “Wake Up Error” solutions:


- Here are the files for Kess SD or TF card. Just reformat your card and copy the files onto it.



- Sometimes wake up error doesn't mean your tool has problem, i use Kess original. when the ECU was tuned and locked. it will show wake up error too ...

Please be specific what car, ECU you working with. its difficult to tell whats wrong here ...



- Maybe conflict in drivers if you have other tools on your pc, try to remove other drivers,and reinstall only kess drivers, have work for me one time



- Firstly try installing genuine software 2.20 will be fine, once installed then un-install it! Use your software (no point going past 2.08/2.11) if it still gives wake error try removing battery in vehicle for 30 mins and try again, or in 'tools' slow the read speed down to minimum! if still no joy just take it out and do it on the bench!

Ktag read Mercedes W211 Delphi DCM 3.2 in BOOT mode

Do you konw Kess v2 master is possible to read Mercedes W211 the 2008 year with ECU Delphi DCM 3.2?

Perhaps not. Ktag should be a better choice to read Siemens/Delphi in BOOT mode.


ECU programming tools i have:Kess V2 + Ktag clone (buy as a kit,saved a lot)



I tried it on my Ford Kuga from 2010OK

i can read the ECU (just choosing the "Identification" option on the KSuite. The Ksuits shows me the info about the ECU, ok.

I tried it it on a Mercedes E220 W211 CDI 125kw (170 HP): Failed

the Kees V2 said to me: "Wake Up Error".

I have read about this error and there are solutions about "Format the TF Card" inside or similar.


Note: This Kess V2 comes from a good and reliable seller, so maybe the problem is that this ECU cannot be read by OBd2

It is a second hand car, maybe the ecu it is already reprogrammed or similar.

This is the car list that i have:

ktag-kess-read-w211-delphi-dcm-3.2 (1)

I tried picking in another W211 models, but not works. Same error.


use this cable:

ktag-kess-read-w211-delphi-dcm-3.2 (2)

Read almost all the posts related to this topic. Now i confirmed problem is not kess. i have simens/delphi ecu, not edc16.


my engine bay:The car is from 2008... Facelift

ktag-kess-read-w211-delphi-dcm-3.2 (3) ktag-kess-read-w211-delphi-dcm-3.2 (4)

This is the Right side :

ktag-kess-read-w211-delphi-dcm-3.2 (5)

The left side (viewing from driver):

ktag-kess-read-w211-delphi-dcm-3.2 (6)

The ECU is located under the A/C Filter. At the Left of the Hood.

See pictures:

ktag-kess-read-w211-delphi-dcm-3.2 (7)

It is a DELPHI like what i was told:

ktag-kess-read-w211-delphi-dcm-3.2 (8) ktag-kess-read-w211-delphi-dcm-3.2 (9)

Engine sticker:

ktag-kess-read-w211-delphi-dcm-3.2 (10)

Siemens/Delphi can be done by Ktag programmer in boot mode.

It’sdelphi dcm 3.2 ecu.Need BDM adapter an make a bridge for two pins.


This is what i found, about delphi dcm 3.2 ecu with a BDM100 programmer
