Launch BRZ with no ECU tune ?
 

Does anybody know if its possible? I seen videos on youtube that people launch the BRZ but almost all of them they have some type of tune (maps) to pick launch control.. Im new to launch control and car tune....

No need for launch control at stock power to be honest.

Slight pointless as Ka-t 240 said the auto would maybe be cool to have launch control but there's really no power so it would just move a meter and bog down would be boring
My opinion

Your right foot is launch control.

Rev at around 4.5k rpm and engage 1st gear as quickly as you can. Mileage (before new clutch) may vary.

Do you know how to do a burnout? If so, then you just have to find the sweet spot RPM to drop the clutch and go with maximum acceleration and lowest wheel spin! C'mon playa!

Don't let the revs drop below 4750, don't allow excessive wheelspin. You'll need to be slipping the clutch a bit to keep the engine from bogging down and falling into the torque dip. It's very hard on your clutch.
