Hello, I was wondering if driving with rev match "all the time" is good or bad for the car? I drive 100% of the time with rev match on because I love how the car sounds while down shifting.

 

Its just personal preference won't hurt a thing!

 

It's good for the car! Less wear on the clutch and syncro's! The whole drive train has less stress instead of a jerking load when you downshift. Not to mention one reason it's used when racing, which is to avoid undesired jerky engine braking by the rear wheels that could cause loss of traction in a turn. I use it all the time not for the noise but so I can drive smoothly and bypass the additional overdrives when coming off the highway etc. For example if traveling in 7th at 75 mph and entering an exit ramp where you'll need 4th as you slow down, just go directly to 4th, the trans gate springs make that easy. Perfect rpm match! I always used heel/toe with all my other standard shift vehicles (which I had in almost all of my DD's) and was pretty good at higher rpm, just blip the throttle. But at lower rpm's hard to modulate the throttle to get a good rpm match. Rev match does it perfectly every time!
Realize some think they have 7 speeds so want to use all of them like an old 4 speed! However the top 3 gears are overdrive and the engine has a lot of low speed torque. No need to row thru all the gears up and down. To each his own!
One thing I found is I had to stop a practice I often used when skipping gears. If going from say 5th to 3rd for example, I would depress the clutch and with it depressed first put the shift level in 4th before going to 3rd where I would engage the clutch. Spooled up the gear clusters. They warn NOT to do that with rev match, it confuses the computer! In fact it was said it could cause damage. Still have to occasionally catch myself!
I also use Rev Match all the time.

 

Mine is on all the time! Really helps with upshifting! And the sound on downshifts is music to my ears!

 

would not recommend it in rush hour traffic.

If your rpms are too low when rev-matching kick in on a downshift, it'll cause the car to "leap" forward a bit, whch is not something you want to do in heavy traffic.

 

Depends on whether you think you can do a better job of rev matching than the computer...

 

It does have a nice sound while driving, but like heel and toeing it has its place. I don't think that in heavy traffic, ie; stop and go, I would be using it. I agree with aj98 in that the lower speed down shift can become a bit jerky.
Also, for those wanting better gas mileage it would be a bit wasteful. But that is nit picking...what's a little gas for the sake of good sound?

 

Hey guys, thanks for all the replies!

 

Yup. I NEVER use it as I learned how to heel and toe a long time ago and simply "blip" the throttle myself when downshifting.

Nanny features are one thing. Being unnecessarily coddled is quite another

 

 

Been driving standard shift vehicles as my DD for over 50 years. In my 4 Vettes and even my trucks between Vettes (and prior my 7 speed Dodge Colt Turbo, 260Z, CJ5 Jeep, modified Corvairs etc) was pretty good at heel-toe (or in the Vettes toe side of foot) at higher rpm but at low rpm, just cursing would often not get it perfectly. For example in town today going from ~50 mph in 5th and making a right turn went directly from ~1500 rpm to ~3000 in 3rd with hardly any braking. Modulating the “blip” to get a perfect match at those rpm’s with the side of the foot is difficult, rev match does it perfectly every time! Didn’t feel coddled! To each his own!

 

I heel toe in my Genesis coupe all the time, but when it come to the C7, the rev match just does a really good job. I turn it on all the time. The only time I leave it off is when I'm warming up the car. Also when coasting to a stop, I now put it in neutral. I have the habit in my other car to shake the stick left and right to make sure I'm in neutral, but that causes the rev match to spin the motor. And with the shifter being so good, I can be sure it's in neutral.
