Let me first start off with - I dont have a date just yet!
But EcuTek - a UK based company has has been working on the BRZ Ecu for over 8 months now!
Like their other Subaru products they plan on doing Speed Density, map switching, advanced launch control , etc etc.
Some of these features will prove to be critically important when putting a turbo on!
I was just sent updated Pro ECU software from them and here is a little screen shot
Hope everyone has a nice weekend.
