Should I have a Kess V2 China clone or EU clone?

Q: How to know my Kess V2 is a China clone or an EU clone? What’s the difference?

A: It’s simple; just look purple PCB, then you can be 100% sure its build EU clone. China have green or red PCB.
But remember, full reworked green Kess V2from China also works well. And it is low budget clone for start business.

Kess v2 EU purple PCB and China green/red PCB can be found here:

http://blog.obdexpress.co.uk/2017/09/27/kess-v2-5-017-china-clone-vs-kess-v2-eu-clone/

It’s a good write-up of Kess V2 PCB.

But you have to know- no matter what the colour of the pcb is ist sa pcb
the main thing is good quality parts thats is all thats needed
a china kess/ktag fgtech or any other board if reworked will work exactly as it should

eu made/pcb is a gimmick in most sellers (would like to see proof otherwise)
all the eu boards i have seen have been china made pcb’s some reworked some not even changed but sold as eu made.
the purple eu made kess and ktags can someone proove where in the eu they are made?
poland maybe or germany etc but as i said before makes no diference whatsoever if the parts are good quality then the pcb’s are all the same

they all use the same project to make the pcb’s

Kess V2 firmware 4.036 supports Trucks read/write?

My Kess V2 firmware 4.036 fails to read truck ECUs. Why? And how to rework?

I bought a KESS V2 CLONE, runs on cars and motorcycles, but the protocols are disabled TRUCK. LISTEN TO BE CHANGING NXP and change the firmware to operate in trucks. Could anyone help?

I LEAVE MY DATA KESS.

FW version: 4.036

Serial number: K10033818

Customer Code: C7514

Group Code: C7514

Reply: I guess you bought the wrong type. There are are many kinds of Kess 4.036.

Some cannot support trucks at all.

You should have a small part of kess supports lots of trucks and motorcycles (called truck version)

See this...

Kess V2 4.036 Truck List:

                          

If you dont want to buy a new kess v2 programming tool. You can change the firmware to  v3.099 with a new nxp LPC2478, new serial and new update with trucks.
Also your china PCB must be preapred to handle the 24v

Personally, You are not advised to do so because of high risk and I hold no responsibilty.

   6. supports more cars & bikes & trucks fully activated

Kess v2 master or slave? original or clone?

It all depends. Kess v2 good clone used be ok for older ecus only, but now also work great with newer ones. and with a slave you will have to rely on the master for your maps whaere as if you have a master you can write your own or choose where you get them from.

Kess V2 or Ktag?

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.

How to solve Ktag Kess V2 NO 12V

Hallo zusammen und dankt allen für Ihre Antworten. Herr, ich sammle Arbeitslösungen oder KTAG oder Kess V2 NO 12V. Hoffe , es hilft jemand aus.
 

Teil 1: Kann nicht erhalten 12v oder Ausgabe von Kess V2
Ich benutze eine Wechselspannung an meine Kess V2 Adapter zu verbinden. Der Verkäufer Darstellung es. es sich 12v und 1A.

Wenn ich meine Kess verwende ich bin, die die nächsten Schritte folgen.

1) Verbinden des Adapters an Kess Einheit 
2) Verbinden des Netzteils mit dem Adapter 
3) Verbinden des USB - Kabels an Kess Einheit und der Computer und die Software TUn

Mein Kess lesen ECU durch OBD-Schnittstelle. Ich las einen Seat Leon 1.9 B.times.E perfekt. Es ist andere EDC16 ECU.

Die Ksuite zeigt es 12,16V-12,30V aller Zeiten hat während seiner lesen Versuch.

Getestet habe ich meine Stromversorgung und gibt 12 Volt

Gelöst!

Teil 2: KTAG NO 12V

Haben Sie einen KTAG Clone seit ein paar Monaten. hat etwa 10 Ecu mit ihm, kein Problem! Seit heute habe ich habe keine 12 Volt auf roten Drähte. Normalerweise Wenn ich lese, klicken Sie 12v Erscheint auf rot und orange Drähte. Nur noch eine Orange. Wenn ich rot verbinden und Orange zusammen funktioniert alles wie normal.

Herr ist das Board mit fehlerhafter Komponente (n)

Changed diese Komponente und es funktionierte.

 

Teil 3: KTAG Kess V2 arbeitet gut mit 12V

KTAG Kess V2 mit den besten Komponenten funktioniert gut

Beachten Sie, dass Red PCB Version funktioniert besser als Blue & Green Versionen

How to rework Ktag 6.070 for Tricore BOOT

Ktag should be able to program with Jtag, BDM and Boot protocols.

However, I have no luck with Ktag 6.070 for Tricore BOOT;

My way is to rework the board
Before rework:Everything working fine (BDM, Kline etc.) except Tricore boot
Connection OK, ID OK , begin reading ok , then jump when reading and finish with “error reading” (between 20% and 44%)
I try with SID807EVO , EDC17C54 and MED17.5.2, same error.

I use Kess V2.11 & Trasdata, same thing

Solved!

The problem is crystal not murata

for fix or change crystal or add capacitors 22pf
crystal murata does not need capacitors

ECU EDC17c54 in Bootmode OK and write OK, Crafter 120hp drive faster , everything is ok

Ps. When searching info on the web, i found some said their Ktag from http://www.obdexpress.co.uk/wholesale/ktag-ecu-k-tag-programming-tool-master-unlimited-token.html perfect for Jtag, BDM and all the Boot application (tricore and ST10). i’ll try next time.

How to unlock/read/write Simos PCR2.1 with Fgtech Ktag Kess

Rviews on  how to unlock, read and writeSimos PCR2.1 from VW Golf VI 1.6tdi.

i have past last week trying many thinks on pcr2.1 and bench flashing .

everything written below is tested and confirmed working by me on 4 ecus /cars ,only on chinese clone not reworked unit : fgtech v54 , ktag 6.070 , kess v2 4.0.36 , ksuite up to 2.15

pcr 2.1 need to be as you know unlocked before writing .

I prefer ksuite to work on this ecu (kess or ktag) , ksuite seem to be more stable than fgtech on pcr but work too : i get error with fgtech on one pcr2.1 , i don’t know why , and no problem with ksuite .

Same day i try another pcr with fgtech and no problem , the one fgtech don’t want to work with work flawlessly with ksuite and car run ok .

So if you have both tools , prefer ksuite seem to be more stable .

After you get you ecu unlocked in boot mode , with fgtech just remove boot and left pin connection , and read or write on bench .

On ksuite tools , you can’t read or write with ktag , only unlock . (alientech need to work on it…)

with kess it’s ok , BUT , you can’t use the tricore module !

The problem is that the harness is plugged in the tricore module . so you have to build your own bench cable : just get a obd female plug on a scrapyard , and wire +12 gnd and can h/l (kline is not used but you can wire it it will make a universal bench cable) .

The trick to get communication error free on both fgtech and kess cable is to use a strong external psu .

when the tool id or read or write the ecu , the ecu will perform a kind of reset , and the big cap inside the ecu will go charging , causing a drop in voltage if your psu isn’t strong enough to handle it . THAT WILL CAUSE THE COMM ERROR . That’s the only thing you have to take care .

when i made test with many little psu (like one you get with your tools) i have seen 7 volts drop some time , so the ecu is shutting down and no comm .

you can use computer atx psu modded to work on bench (green wire plugged on ground to power on ) i think anything that can provide +12v 2A will be ok . i didn’t need more than 12v just a stable 12V . 14v unstable will not be ok lol

that’s why on the car you have no problem , car battery can handle the cap charging current .

There is no immo caused comm error on this ecu , psu is the problem !!

so in conclusion : good psu and obd home made bench cable , remove tricore module on kess v2= 100% tested bench flashing solution for pcr2.1 .

Many many many thanks to gzk of his contribution to the awesome write-up.

Is Ktag 7.026 better than Ktag 7.020?

Is it worth buying a new tool just for this upgrade?

See how do people think of this?

Discussion at http://mhhauto.com/

1

This 7.026 update is all ready available from EU. “Problem ” is resetting. NXP need replace when time to reset tokens, after 30 writing. That can do few times if have good skills and good tools for this.

2

when you turn 1 job down you will think l should off upgraded , alot more gpt connections on newer ecu,s

3

7.026 is the one with 3 NXP mcu’s . everyone with 30 writings. i use it allow. all working ok and i think by the time i will use all 90 writings a new tool will come.

4

if you need Denso Nec NBD family the only tool doing this 100% is my 7.026. 7.020 will NOT MAKE DENSO NEC NBD even 15%. there may be 1 or 2 of the ecus it can do but that’s it. and no one aside from us can offer you 7.026 as its socketed solution. anyone who tells you 7.020 can make denso nec nbd 100% is just gonna take your money

5

I have ktag 7.026. Tool is OK.
Although it requires a good coffee machine… my reworked ktag 6.070 is MUCH faster

6

Ktag firmware 7.026 have MCU for change

Ktag firmware 7.020 not reset CFG

7

Ktag 7.026 TOKENS 30 in 1 MCU

Ktag 7.020 UNLIMITED

8

This ktag has some nice features like toyota denso or VAG GPT edc17c74

9

some EU seller claims that he has version without tokens limit.

10
Ktag 7.026 Russian clone has fixed firmware with token count stopped.
I use kess and ktag. No any headache. No heating to unlock, no nxp changing.
11
For kess v2, As i know, for 5+ firmware, protocol files crypted individually for each original.
You can’t update different devices with same files.

Since Kess V2 4.036 a lot of protection added.
For ktag, i think, the same.
Take care before spend 2000+

In summary, there are good and bad reviews of ktag 7.026. Hint for you, do not rush into new versions. Time will tell you good or not. Before this, go for Ktag firmware 7.020.
