Hello
2011 L322 with 4.4 tdv8. Tried to put stage 1 tune to my ecu. Computer lagged and and i had to start again. When it completed i tried ecu in car but car wont start now... I restored backup which i made earlier but it does not help. I can read and write ecu with ktag. But when i try to read fault codes fault code reader it just says unable to read fault codes. But still i can see version information etc with fault code reader.

And yes i checked all the pins of ecu. All other ecus gives fault code about connection to engine ecu.

Can i buy just some random edc17cp11 ecu or does it have to be from 4.4 tdv8 range rover?

 

Did you ever sort this ??? I have a similar problem,

 

I restored backup and it sorted it.

Tune was damaged or faulty. I got new tune from supplier and it worked.
