I've actually been working through this and it can flash it your correct but the current version doesn't close out the ECU right and doesn't update the EEPROM correctly (with Full Write Mode). I have to do a (Diff Write) to get it to work. Only way i can support writing to the ECU. But the Blue cables sometimes suck... so ive started using an openport 1.3U with great luck.
Do you have enough knowledge to dig through the nef source code and help fix it?
