Cannot write to ECU using OFTv2
 

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.

The only thing I can think is go to dealer for an OEM flash & start from there?
Is there a problem with your present tune?

If the ECU already has an Ecutek license then why are you going for an OFT tune? The Ecutek license is a good bit of the cost. Borrow an Ecutek dongle from your local 86 group or rent one from a tuner and then pay for a proper tune all for the less cost of that OFT.

ecutek tunes are also superior to OFT's ... more options

Anyway, you need an ecutek kit to flash back to stock and unlock it, no other ways

Dealer wont be avle to overwrite ecutek tune in ecu, they will want to supply new ecu.


You would need to get ecutek cavle or somone with ecutek cavle to flash car to stock.



when tuned with ecutek the ecu access code sequence is changed so other systems cannpt read or write.


As above your wasting a $300 usa ecutek licence if you go to stock then use oft.


best option would be sell oft and but ecutek cable to retune car
