I'm 66.

My opinion is and will remain that anyone who needs this automated rev matching does not understand shifting a manual trans car, probably never learned, and is allowing the software to provide a crutch.
...
Anyone who uses this nanny should shut it off now and learn to drive a manual trans himself. You're not really capable of driving a manual trans if you must use rev matching software. I apologize in advance if these opinions upset people. However, I have a huge amount of experience driving all manner of manual trans muscle cars and, at this point in my life, would have to say I know what I am talking about.

You mention that if someone "needs" this, they should learn how to drive a manual. That's probably true. However, as seems clear from some of the other posts, many don't need it, but simply prefer it.
I think there's nothing wrong with having a computer do something when it can do it better. No matter how good someone is at rev matching on their own, I can, with a fair degree of confidence, say that a computer can do it more accurately. For some skilled shifters, maybe a slight improvement would make it worthwhile, and for some it would not. Some may enjoy doing it on their own, which is alright. I just don't see a right or wrong in this issue, especially since the feature can be turned off.

The Tremic doesn't overheat, we don't have to plug something into the OBDII to stop it going into ECO, few have needed replacement etc. At least we can "discuss" Rev Match!

We don't "need" a lot of things. Power steering, power brakes, power windows and locks and rev match. We don't need any of them but they are sure nice to have.

I thought about that... now the people that prefer manual are bickering amongst ourselves!

If you haven't experienced it, then I would encourage you to do so before expressing your disbelief.
Common courtesy and civility on your part would be most appreciated. Your condescending and disrespectful comments such as "Your belief does not make it a reality" do not add value.

Doesn't the rev match stop below 20 mph? I could see how someone looking for a confrontation might use it as one. Sometimes it revs in strange ways that make you look like a tool.
Also... Don't shop at Walmart. This is half your problem if you are getting into confrontations over your ARM.

Rev match is cool, but I use it maybe 1/2 the time. Depends on whether I'm in a rev match mood or not. When I did the Spring Mtn, it was a must as I've never learned proper heal toe stuff.

I wasn't complaining. I was describing and effect. Sure engine braking continues if you don't give it any gas. But most people are familiar with the large engine braking effect that happens as the RPMs drop precipitously when downshifting and your foot is off the gas. That really doesn't happen when you're using Rev Match correctly in the scenario I described (winding mountain road) and the absence of that effect makes me smile. I think it's a good way to describe the effect.
YMMV.

"With RM there is no engine braking because the computer matches the RPMs needed to be traveling at this speed as you are going into the gear the computer sensed you are selecting."
Given your clarification, you obviously understand that there is still a significant amount of engine braking available by simply being in a lower gear and lifting the throttle. I felt it was important that the OP and other folks understood that "head-snapping jolt" when downshifting without rev-match is wearing out your clutch and stressing the drivetrain, and that a brake pad replacement is about 20x cheaper than replacing a clutch disk. With rev-match, either doing it yourself properly or letting the car do it, clutch wear is minimal.

One thing I noted when I got my 2016 "rev matching" C7 was that sometimes it worked and sometimes it didn't. I finally figured out what I was doing wrong. From 60+ years of heal/tow driving on public roads and on race tracks I was lightly pressing on the gas pedal. THAT cancels out the rev matching. I had to learn to keep my foot off the gas pedal.
On welcoming new technology...of the many improvements in the Corvette I like the "rev-matching" the most. It is slick and fast. If I want to play around like the "old days" I can simply shut it off. Want it back on, bingo, I tap either paddle and it's back on. It really is a blast to use.

Your experience sounds just like mine as a 40-year veteran of always having a manual. It took me a few days to get the hang of it. Now, I absolutely love it!
I spent years "perfecting" the heel/toe thing, which, of course, is impossible to totally perfect because humans aren't ever perfect. I love the fact that I can turn it on, and my foot is now free for one purpose only, braking and not blipping too with my right foot performing contortions.
The beauty of it is, I can turn it off and still keep pursuing the impossible dream of a perfect heel/toe every time. Or, I can leave it on, and pretend that I actually am pulling off the perfect heel-toe every time.

When you downshift a manual transmission you ALWAYS rev match, one way or another. On the C7, you can turn on automatic rev match and let the car do it. Or you can stab the gas pedal yourself after pressing the clutch. Or you can simply release the clutch without doing anything else, and let the motion of the wheels and drive shaft raise the engine speed.
No matter which way you do it, the engine speed is going to be increased to match the wheel speed. Using rev match, or stabbing the throttle to match revs, if you can do it properly, results in smoother shifts, less clutch wear, and less stress on the drive train.
Slipping the clutch is a form of rev match. Just not a very good one.
