Interesting experience tonight. Took my car back in for 15k service, and in the meantime inquired about the idle drop TSB. I watched them try to flash it for a little over an hour and the software kept coming up with an "unable to communicate with ECU" error. I'm going back in on Monday for them to try and diagnose the issue.
This was their first time trying to flash an FR-S. It could be an issue on their end. I do, though, wonder if it's an issue OFT could have caused -- anyone else done this successfully?

If you can read and flash your ecu with your OFT then all is ok.
If you carn't after the dealer has touched it check the fuse for the 12v supply to the obd port .
OFT tunes do not lock, encrypt change seed keys or change anything to do with flash process.
The dealer gear is either crook or they are "wombats"
