My car doesn't seem to like to rev match Downshift in M (manual mode)..
It rev matches downshifts in S+ mods but not in any manual mode regardless of S, S+ or M..

in S+ it rev matches on downshifts loud and clear. Anyone else?

I'll try M at lunch and see if I still have the blips. I do have a tune that makes nice aggressive blips in S+. None in C, a bit lighter in S, and full on in S+. Have not tried M yet. I will reply later on this.

You have two choices if you want a rev matched downshift in manual mode. 1) Drive the car harder and be on the brakes hard when you request the down shift. 2) Apply a little bit of throttle while down shifting (ex. you are cruising at highway speeds and want to pass).

Mine rev matches consistently if the needed matching engine RPM is high enough. The threshold (i.e., the matching RPM needed) seems to get lower as you go up in aggressiveness from C to M.

For example, in C, for the rev match to kick in, the matching RPM might need to be 4k before it'll blip. When in S+, it might only be 3k. If the matching RPM is low, say like 2k, it generally doesn't bother.

And as dika said, hard braking (at least in S/S+) will trigger rev-match downshifts. My guess is that, in auto mode, it can better "prime" the transmission to make the downshift because it's predicting when that will happen as opposed to trying to react as fast as possible to your manual shift.
