Yes, both ways. If you upshift at too low an rpm, it revs briefly. I was real skeptical about ARM when I first got my car, but I am amazed how well it works. I leave it off every now and then to keep up my rev matching skill.

Thanks for clarifying, when I get mine I will keep off most of the time as I am proud of my rev matching skills (and years go by when I drive manual cars)

A poor analogy. Libraries have removed card catalogs, so you don't have a choice. And car manufacturers are removing manual transmissions so you won't have a choice. Rumor has it that the C8 won't have that option. Which kind of begs the question. Why are you still driving a manual? Time and technology changes and autos are amazing tech.

A poor comparison. Autos make driving a car mundane. Great for getting from point A to B. However takes away the actual enjoyment of driving IMO.

Totally agree, really dont need this guy to ask all of us why we are driving a manual. If he can not figure it out he should try driving one and experience the utter joy we all feel.

You'll never notice it on up shifts. However, if you turn it off, you'll notice that you don't Rev match as well as it does on up shifts. Downshifting is where Rev Match shines.

rev match enabled 95% of the time, why wouldnt you? can really save your *** if you mis-shift it and suddenly drop down lower than intended.

you could make an argument for leaving it off during the break-in period, yes.

the rev match will not rev the engine higher than 5200, i believe it said.. something like that. 7th->3rd under normal circumstances is no big deal at all, other than the increased noise.. which of course suits me just fine. its an expensive and awesome car, enjoy it every way you can. someday youll be dead and none of this will matter. therefore, in the meantime.....

=D

On upshifts, Rev Match will hold the rpm at the proper point for your speed if you happen to be extra slow with the shift, whereas the revs would have fallen below the ideal point had Rev Match been off. The revs also seem to fall slightly slower during the upshift when Rev Match is activated, at least to me.

I believe you. I drive a manual. But he said this originally:
not using it is like saying you prefer a rotary phone over a cell phone because that’s how you learned how to make calls. times and technology changes. Active rev match is amazing tech. but hey - everyone loves looking things up in a card catalog at a library over using Google - right? It’s a more engaging way to get information...
To me active rev match takes away the actual enjoyment of switching gears. The engine is always in perfect alignment. You don't even feel it. It may as well be an auto. On the track it serves a useful purpose, but on the street it's another example of too much tech. You don't really need it.

During rev Match there is a noise when you shift gear as if rev match system activates kind of some catching noise , is that normal?

It wouldn't have hurt anything as long as you didn't let the clutch out. Letting the clutch out and getting a mechanical over rev can lunch the engine if the speed differential pushes the rpms into the 7000 or more range.

I use Rev Match all the time. It is far better than heel/toe which I have almost forgotten how to do. I have never had too many or too few revs on a down shift since I started using it.

If I engaged RM, I'd probably STILL blip the throttle on a downshift.

Old habits and all that....

Have mot messed with the rev match yet...

My understanding is that using rev match on downshifts is not a good idea if you are engine braking because the car won't slow down?

Is that true?

Shouldn't matter. You're not applying throttle after the downshifted gear is engaged so engine braking will still happen

OK, so what is the purpose of it then? I know my SRT has it, when driving in manual mode in sport and track modes, and I noticed it kinda makes the car surge a bit when downshifting. It's freaked me out a couple times while parking.

I like the braking that downshifting provides when I make a turn on the street. Not worried about clutch wear as I have never worn out a clutch in 35 yrs of manual trans. I only use rev match for the novelty of it.

I use it 90% of the time including daily driving. I tend to leave it off when in Touring mode when highway cruising just because it seems like overkill. Also switched off if I’m stuck in traffic with constant shifting since as soon as you clutch in it revs up when all I really want to do is coast a bit. I could never heel / toe on the track very well because I was always concentrating too much on my braking technique. Now with rev match there are no more worries about that. Even on the street I come down thru all the gears now just to enjoy the sound and seamless shifts.
