KESS V2 not works with k-line or does not work well

Problem:
Feedback from some KESS V2 user: Car ECU Programmer KESS V2 not works with some k-line or does not work well.
Solution:
The 9613 chip is Chinese standard, not international standard, so the technical parameter is not compatible, and neither is the chip from Malaysia Thailand and Taiwan. Advice users buy the America-made 9613 chip to replace it.
In the near future, Chinese factory will use Chinese 9637 to replace 9613, and this error will gradually disappear.
