Part 1: Kess V2 5.017 Red PCB rework experience

Bought a Kess V2 5.017 china clone, but no luck.
I can try to read but writing is sometimes danger.
power supply for akku. When I write flash, the ecu need a lot of power.


Searched a lot… thought i should rework the inner board.


Then i did something…







Murata filters:

NFE61PT472C1H9L (connect ground for all of them)



1uF – 35V

220uF – 10V

10uF – 16V tantalum
