I don't know of anyone that's cracked the FRS ECM just yet
It's been cracked for a while now. There are a few programs out there now. The car may be N/A, but you're still dealing with 12.5:1 compression, port injection, and direct injection. That may complicate tuning, but since I've never tuned I really can't say for sure.

Save your money and spend it on Autox lessons because G-ride (or whatever his real name is) took me out in his stock BRZ and made me grin just with skills ( but he practices pretty much every weekend on closed courses and I don't grin much)

A stock BRZ tune is fine but a stock driver is **** is the point I'm making so don't waste money on a pointless tune no matter what the inter webs says until 2 one hundreds of a second is costing you a win
I appreciate it Supposedly though, there's an issue with the stock tune. Something about misfire/detonation when shifting in the higher gears in the upper rpm range. However, I haven't seen that brought up in a while.
