As I understand there is no way of unlocking the ECU pass if one is set unless you start form scratch .
I have G4 for R34 GTT and unfortunately things didn't work out between my and the tuner so want to know what are my options.
I think none unless I start from scartch and do street maping.
Hello, you are correct there is no back door to break the password even at link head office sorry you will need to start from scratch
This is probably the way for tuner to lock in the begginers . Do you see this done at many places?
Some tuners lock the ECU to supposedly protect their IP. In reality from what I see, the majority of tuners who lock their maps do it because they have no clue what they're doing and don't want others to see their maps. The only time I ever locked a map was when I was pretty confident the customer was going to 'have a play' after I'd finished. this just protected me from them blowing the engine up and coming back to blame me. If they asked for the password I would provide it but that gave me the opportunity to tell them that if they wanted to make changes, don't blame me if things turn ugly.
Had a follow-up question and thought to use this thread.
I have little experience with ecu reflash but the concept is the files are encrypted and using a software they can be read.
Now by encrypted I am not sure if this means there is no definition file so unless ones spends time to work out what each hex value means etc then sort of it is a gebbrish langauge or encrypyted.
or it is simply encrypted and needs a key and I wonder how companies discover this. is the key stored on some module and they find it etc
now to my question, can the same approach not be applied and read the map from Link. I would say surely if we can read manufacture maps which are not intended to be tampred with and are protected then Link should be sort of the same.
something like kess or ktag if it supports the link chip
in brief, bmw will spend way more that link to protect their ecu so if bmw can be read then could same principle be applied to link
