What is the exact difference between kess v2 slave or master?
Is it better to buy original or clone are good?
It all depends.
Kess v2 good clone can only be used for older ecus but now also work with newer ones and with a slave you will have to trust the master for your maps as if you have a master you can write your own or choose from where you get them.
Kess v2 master:
If you have a master version, you can work directly in the program you have to write in the vehicle (tuning, egr off, ....) and rewrite directly.
Kess v2 slave:
If you are a slave version (which depends on a master (who modifies), you read the program (encrypted by genie), you send it to the master, he does what you do (paid money) and he re-sends it for you to write on the ecu machine.
It is expensive for the slave version user who depends on a master.
Kess v2 slave in master: kess v2 clone floods the market that's why there are many genuine kess slave for sale, besides most slaves can't do boot mode the advantages of using original kess v2 and converting it is you have a genuine original kess hardware, so the chances of hardware failure is less if you can fit genuine nxp chip, then great, otherwise you will convert to chinese NXP with chinese firmware
advantages is that the converted drive does the initial mode, and in some cases it has more protocols, you already told yourself you want more freedom, and probably better tuning files!

The last one: Kess V2
KESS V2 is an ECU programming tool that is perfect for OBD usage, while KTag is perfect for Jtag, BDM and all Boot application (tricore and ST10).
With KESS V2 you program directly through the vehicle's OBD port, while with Ktag you
need to unmount the ECU and open it, after that you can do the read/write operation.
Many ECUs have the advantage of being able to read and write from the OBD port (so KESS V2 is perfect) but there are many ECUs that need to unmount from the car and open and this is the case for all ECUs that need to be programmed with the protocols Jtag, BDM and Boot, so KTAG is required.
