OK, I have Learn EMS Mode working, ECU now linked to SCU.
I have Got Tuning Mode working and Read mode working. Downloaded XXXX-saws-read-0.tnr file and sent to SAWS tunung
Got back XXXX -tuner.tnr file from SAWS and copied it to same location as the read file. That is both old and new files are in the same place as instructions.
Log back in to Pscan / BMW mode / Extras / Tuning / Saws / Write and it said file XXXX-tuner.tnr file can not be found.
Where is it looking? XXXX bits are same in original and tuned file.
