Why you want reset it...?
Hello, i need to reset obd counter on EDC16u1 ECU. I red that kess can do this. But i not cerntain which version also if it can be done over obd.
Is there some good clone tool that can reset counter over OBD port without needing to solder it to ECU and do it over BDM?

Because i am tuning my car myself learning about it in the process After 88 successful flashes i cant write it over OBD with mpps anymore. So i am suspecting counter.
Read eeprom and post it here

88 my own versions and surplus was there when i bought the car.
In attachment full read from today.
For eeprom you must read with BDM

I dont have hardware for this. Thats why i ask in start of this topic about which hardware would be able to do this over OBD?
cheapest way should be a eeprom programmer / solder station...
open ecu and read eeprom...

Actually i have a bench table with needles. I bought it for clone galleto but it dint work in the end. Could you be more specific what hardware exactly becuase i have apsolutely no knowledge what sort of programmer should i buy. I dont mind buying some clone hardware for just this one case.
Bump? I realy need help here. What clone hardware should i buy that is able to read BDM or zero counter over obd?
Hi
to read it on table you can use lots of programmers like UPA, Carprog, Xprog etc.. i do have Kess but never tried to read only eeprom data with it, coz its more secure to read it with the eeprom removed from board. i tried lots of times reading onboard with clip adapter for carprog but many time reading are wrong. so most secure way is to remove eeprom first then read it. Here you a picture where eeprom on edc16u1 should be. Eeprom type is ST 95320wp

Hi
Avdi can do it thru OBD but not safe because it edit Ram before persisting in eeprom.

Maybe old vagdashcan tool too. Never tested.

If you read eeprom manually, you can edit following addresses (edc16):
programming attempts: $41
Successfull attempts: $42
Flash tool code: $43-$48
Vmax (x100): $48E-$48F, $4CE-$4CF
But I'm not sure if you need update checksums.
Please keep me informed if you test a tool that can update thru obd2 plug.
