So I bought my 2015 FRS a few months ago and recently learned that it has an Ecutek tune on it, however, I want to go with OFT, and now when I try to flash an OFT tune it refuses to let me.
Is there a way to flashback to the OEM tune without an Ecutek dongle since one didn't come with the car?
The OFT gives me the 10010 Error when trying to write data however I know it can see the ECU because it is still able to display live data readouts so I don't believe that the connection/ key position is the problem.

If anyone has any advice on what to do please let me know. I have emailed OFT but their customer service is very slow and I wanted to see if there was an easy solution that I may be missing.
