Q: Any success with edc17c46?

A: kess v2 fw 4.036 with update board work 100% on this ecu

tested from me friday.  all ok

you will search only file ori, mod and write

 

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.

 

Q: How safe is to do with kess?

A: Kind of dangerous, no matter with which tool.

I do not recommend you to write with Kess clone, Ktag smoothly

 

Q: It is safer to open the ECU and read in BOOT mode?

A: Trad it in boot mode read it fine but getting boot error when writing on boot mode

 

Q: What about protocol 399, id only and write back mod file via obd

A: this works fine with Kess fw 4.036

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

pin 15 = green

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.
