Differences between KESS and KESS V2 Master

Yesterday, a customer inquired me what is the difference between KESS OBD Tuning Kit and  kess v2. Indeed, these two tools are very similar no matter in their names or functions. But they are different in car models they support and the way they program ECU chips.

1.KESS V2 Master is a polished version of KESS OBD Tuning Kit. As we all know,  kess v2 only program via OBD2 port, but KESS V2 also support programming via boot mode.

2.KESS V2 is able to work with both cars and bikes, while KESS simply does not support bikes. Besides, KESS V2 can work with more brnads of cars and newer ECU chips than that KESS.
