Ktag and Kess v2 ecu programming review

Bought a bundle of Ktag and kess v2 last week.

And the kit arrived today. Shipped from China.
Attempting to use the ecu programmers this weekend.
Installed all appropriate software.

I run it on Windows xp

Edit: i successfully tested on some ECUs using the ktag and kess. Used without network connection.

Chinese pcb but high quality, i have this kess and ktag pcb in my old clones ( kess v2 fw: v4.036 and ktag fw: v6.070 and work well without any fault, also work with 24v)

 

kess and ktag tested in old ecus, works perfect (Sim 32, edc15p+, me7.5, me7.5.10, me7.5.30, Edc17c54, etc)

New Protocols Ecu Tested:

Ktag, Ford fiesta 1.6Ecu Siemens EMS2211 Tricore
Reading OK (very fast)
Writing OK
Cheksum correction OK

  
Kess, Toyota Hilux 2.5 D4D Engine, DENSO 175822-887ID OK
WRITING OK
CHEKSUM CORRECTION OK

  Kess write in 2 minutes.

Ktag, Toyota Hilux 2.5 D4D DENSO 175822-887 (needs luck)Reading ok
Wrinting ok
Backup ok
Cheksum Correction ok

    

Kess, Vw Amarok 2.0 163cv OBDII WritingID Ok
Cheksum OK
Writing ok

In short, KESS V2 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. And that is why i bought Ktag and kess v2 together.

Checksum Family Manual for ECM Titanium v1.61

What is Checksum?
Checksum is the security algorithm with which are encoded files stored inside the engine control units; if the modified files you are tuning, it wasn’t signed with the correct Checksum algorithm, and the ECU will be blocked.

It is very important to know whether the device used for program the tuned file to the ECU already running CheckSum or not; Some ECU tuning tools, like Kess V2 and Ktag, are developed to calculate the CheckSum and you don’t need to buy the same Checksum family also for ECM Titanium.

Why you need Checksum Family?
To correct the Checksum of modified file using the new ECM Titanium, you must have the Checksum Family for that particular ECU.

What will happen if you don’t choose the right Checksum family?
Once you have selected the Driver for tuning the original file, the software will notify you if the ECM DataBase contains the Checksum family needed for signing the modified file. If you haven’t the right Checksum family software will shows the following message:
Checksum algorithm not available - a file with no checksum changes will be created

If the message appeared, the software will return to the main window and the CheckSum Family box, in the Selected Driver panel, will be colored in red and will present the number of CheckSum Family to download.

Where is the CheckSum Families?
To find out which CheckSum Families are in your ECM Titanium, you just
go in the main software window,
choose the menu Tools,
choose Checksum,
then click on Available Checksum

a new window will open with the list of Available Checksum Families:

available families that are stored on the USB dongle are colored green
ALL checksum families available in this cracked ECM TITANIUM 1.61
Note:
Some free versions or uncracked version on the web cannot offer all checksum families available

those in red are not present

How to download a new Checksum family from Internet?
You don’t connect to the Internet to download a new Checksum family on your own. All checksum families are available in ECM TITANIUM 1.61 at http://www.obdexpress.co.uk/

[tip] Read BMW F-series EDC17C41 using KTAG clone

Here are some tips of “reading error” for you when reading EDC17C41 DDE8 520d F10 ecu with Ktag clone, offered by experienced users.

TRY OWN YOUR OWN RISKS!!

Tip 1 - replace oscilator near the nxp processor on ktag board

Tip 2 - need boot and 2 rainbow cable yellow and orange and you have placed the yellow and orange on the wrong spot

1.GREEN-CAN L
2.ORANGE-VKEY
3.YELLOW-K LINE
4.ORANGE-VKEY
5. RED-VECU
6.BLACK-GND
7.BLACK-GND
8.PURPLE-VPP
9.RED-VECU
10.WHITE-CAN H

Tip 3- to rework ktag hardware is necessary with good component, buy too necessary good power supply

Tip 4 - ECU tuning tools for reading BMW F-series EDC17C41
Ktag v6.070 --> YES
Need rework hardware to read EDC17C41 as tips above say
KTM100 v7.003--> YES
BMW ecu EDC17C41 is newly added in KTM100 fw: v7.003

FGTech--> Risky to try!
ECU EDC17 C41 - TC1797 Internal Flash

Kess V2--> NO!!
Kess v2 can’t read and write this type of ECU (EDC17C41), ECUs on the same car model in different areas are sometimes encrypted in different ways, and therefore the tool cannot always work on the same car model.

NOTE:
WE’RE NOT RESPONSIBLE FOR ALL YOU WILL TRY.
GOOD LUCK.
