Rev Matching

[Barnold]

SO I sat in a Vette the other day and they had paddles that enabled a rev matching system for when you downshift. I know you can do this with you foot, but I would love to have a button that would enable rev matching. Press button downshift computer see what gear you are going in and revs up as you release the clutch. I think that would be a fun option. I know all you old school guys that know how to drive a stick thinks this would be wrong, but a no think system is what I want sometimes.

Let me ask a clarifying question. What you're describing with paddles is probably just a regular auto/DSG-type gearbox, which allows quick downshifts. However, I know 370Z (and maybe the new Vette?) have a system where you still have a regular manual gearbox, however the ECU can revmatch for you. There are no buttons needed, it will do it on the fly as you clutch in and downshift.

In the case of the latter, there's no reason to own an actual manual trans if you're not going to want to revmatch a downshift, especially in a sports car. That in and of itself, is a large part in enjoying it.

That said, when looking at a DSG-type gearbox, I don't mind them at all. I'm a manual trans enthusiast, but not a snobby purist. DSG has its place in the enthusiast circle.

I think the new Vette 7spd manual does have active rev matching. I was so overwhelmed with cars and girls at the auto show I don't remember for sure.

It would be a cool feature but I suspect it wouldn't work well with our huge a$$ flywheel.

Yes, the C7 Stingray has computer controlled active rev matching for the manual transmission equipped. The paddles are wired in but I do not believe the operation of rev matching is dependent on their being used.

I think once our 1.4T engines are modded to 300HP active rev matching would be nice. That would also mean the M32 has been completely rebuilt.

The C7 also has a gear position sensor so it knows exactly what gear you're downshifting into - so it can appropriately rev the engine.

Our cars have no such sensor and rely on RPM / MPH to calculate the current gear.
