Both of these work on my 2013 "stage 2" FRS.
They don't know who originally tuned the car so unfortunately we can't just contact the tuner and figure out if they locked it.
I know on some DSMs and the EVO 8 (and 9?) it is common for tuners to lock the ECUs and there are some tools to unlock them. Does that exist for the FRS?
I know one option is to just overwrite the tune with a new one, but we would really like to have the current tune which works in case we screw it up.
Any ideas? Thanks

If its forced induction and you cannot read ecu with oft or tactrix, it very likely its an ecutek tuned car. Unfortunatly it also possible its brzedit but less likely.
If you know somone with an ecutek cable they can do a Query Ecu for you and it will tell you if its ecutek tuned as it will tell you if ecutek licience present in ecu.
If it says no licience then it brzedit.
Also most ecutek tunes will have multiple maps. Switched via cruise control, start xar the with cruse control off, puul cruise stalk towards you for a couple of seconds if tacometer jumps to 1000,2000,300,4000 then its ecutek tuned.
If its ecutek or brzedit you wont be able to read out rhe current tune or alter current tune, all you could do is write a complete new tune to car. This is evwn if you have brzedit or ecutek cables. Both systems the tune and ecu is locked.
To unlock you need to flash back a stock tune with the correct tune system.
If its ecutek you might as well stick with ecutek as the licience in ecu is worth $300, and its a good system for forced induction.
