Q: Has anyone managed to write the following ecu by obd using china kess v2 v4.036 tgat has been reworked. Using a original file from alien tech
A: Yes, it writes without issues. But still don’t get so confident with VR. Better boot it up than you can do it by obd . Stay on safe side. Thats why mpps ori will not offer VR as it is always rullet. Many other ori tool have problems with VR as they don’t match.

A: Kind of dangerous, no matter with which tool.
I do not recommend you to write with Kess clone, Ktag smoothly

i did a seat leon fr and passat with this type ecu
you have to ID the ecu, download an original file, tune it, then write via obd
Q: Can you post your wires good position for all users?
A: This is correct wiring for tricore adapter cable,
pin 1 = brown
pin 2 = purple
pin 3 = not connected
pin 4 = blue
pin 5 = 2x red
pin 6 = not connected
pin 7 = white
pin 8 = not connected
pin 9 = orange
pin 10 = grey
pin 11 = 2x black
pin 12 = not connected
pin 13 = not connected
pin 14 = yellow

I found pin 1, pin 2, pin 14 and pin 15 to be wrong on chinese clone cable and this seems to be the case with a lot of them after researching.
