Why to buy Kess v2 and Ktag 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 (Ktag 2.13) 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 to buy Galletto 4 and kess v2 together?

Galletto 4 work with truck, including Benz truck, read and write ECU via both BDM and OBD; KESS not works with truck, read and write ECU via only OBD, not BDM.
