No clutch on downshift. All by ECU.

You must have a 2014 car that hasn't been re-flashed.

I know what you mean, I have a 997 and the 991 feels like a Cadillac. However the 991 is just as tricky at the limit, if not more so because it can catch you unaware. Once you figure out how the car goes you will love it

also, for those shifting down with higher rpm's... as far as I understand and from the carrera cup weekends I did in the car, if you're running the bias -1.4 which i believe is 45/55 then you don't want a lot of rpm on downshifts... shift down later
far cry from the drama and mechanical symphony that was a 997 in a big braking zone, but i guess progress is progress

Is -1.4 the "preferred" bias? I know there is no magic number. What do most competitive guys run??
Seems like my dash says either .7 or -.7 I will need to look this am.

Dry normal circuit maybe yes. I was a 2.2 guy on the 997 which was about 50/50. Ultimately use whatever you like. Your engineer should be able to help you depending on your braking trace and the circuit.

Agreed in general. I always use 50/50 baseline in the 997 and adjust from there based on track conditions. 991 bias split I based from I forgot. But the 991 brakes are so much better !
