I think it is with the synchro rev. Mine is annoying that way revs when I don't want it to. People think I want to race when I am downshifting thing revs for no reason other than to waste gas. I had it off for a while and enjoyed the car a little more. The idea is great, but the program needs modification should not rev match when I am slowing or want to use the clutch to help brake.

The whole idea of SRM is to help when downshifting going into a corner, when you are slowing down. It's intended so you don't use the engine to help slow you down. That's what the brakes are for.

Huh? Rev matching while downshifting isn't a new thing. The SRM just uses a computer to assist you in doing so. Down shifting before a turn is used specifically (in racing at least) to assist the brakes in slowing down and allow you to be in the correct gear coming out of the turn at maximum acceleration.

It has nothing to do with braking really. Yes there is a slight engine brake effect, but the reason that you blip the throttle is to synchronize the gears for a quicker smoother change (racing gearboxes often don't have synchro's). Engine braking happens but it is actually not desirable as it messes up your brake balance. I've taken to downshifting a lot later and at lower RPM than I used to for that reason.
