I don't get it...Especially in the C7 Vette. It's a manual, with paddles? Someone please explain?

I think the paddles just switch the rev-matching feature on and off.

You can turn it off.

I think it is a cost cutting thing. The paddles are there on both automatic and manual vehicles. Same between both cars. Weird, but I saw it on a review of the car from ThatDudeInBlue on Youtube.

it's basically matching the revs for you if you use them. I just read yesterday that it helps in traffic to reduce wear and tear on parts.

I dont get what you don't get. Could be the NyQuil talking.

Oh, is that it? I thought it was a manual with the option to paddle shift it...My bad.

So do you only tap it once to activate it or how does it actively work? It allows you to shift without the clutch?

This is the way I understood it. It's meant to help with driving in slow city traffic because constantly shifting between 1st and 2nd gear on the way to the next stoplight blows.

Aaron James > K-Roll-PorscheTamer

yeah, you still have to clutch and shift like normal, rev matching just electronically sets the engine rpm while you clutch in for smoother shifting and clutch engagement. Paddles are just on off switches.

they are on off switches for the rev matching stuff.

You tap your heels three times and say "i wish i could downshift correctly" and itll do it for you.

Oh, it's much simpler than I thought. Thanks. :)

!!! UNKNOWN CONTENT TYPE !!!

This one might be the coolest feature we've heard about yet: only accessible on Corvettes equipped with a manual transmission, ARM assists the driver to shift smoother by matching the engine speed to the next selected gear.

ARM works by monitoring the operation of the shift level and the clutch, and adjusts engine speed to match a calibrated value.

On downshifts, ARM will increase engine speed before the clutch is engaged

On upshifts, ARM will decrease engine speed before the clutch is engaged

The rev match is maintained for a brief period between shifts and is deactivated if the shift is not completed, allowing engine speed to return to idle.

Essentially, you still need to depress the clutch, but the system will manage the throttle for you. An example is blipping the throttle to match the engine and transmission speeds on downshifts.

To turn the feature on or off, simply pull the paddle shifter once.

That is simply mechanical engineering genius right there! I need to see this work in person, too bad I don't know anyone with a Corvette older than 2004!

How's it going by the way!

Right now, I'm taking an interest in Vipers, it's a weird car.

Doesn't the 370Z have this?

Roadster Man > CAcoalminer

If I don't have to blip the gas, I'm going to be able to downshift mighty quick. I am really curious how the car manages to keep up with the driver in all of the auto rev-matching cars. I also wonder if it can handle a 4th-to-2nd shift.

CAcoalminer > K-Roll-PorscheTamer
01/09/2015 at 00:07

It is indeed especially since learning to properly downshift is own of the most difficult parts of driving a manual vehicle. With this feature, you can still enjoy the car while perfecting your technique. Also, it probably makes traffic much less hectic. I haven't watched it but this video may show it in action:

Everything has been going very well. Thank you for asking. The grandkids are all back in school or are getting ready to return to college, so it will definitely be a bit more relaxed around the house. Haha. How was your Christmas and New Years and how have you been overall?

They are indeed. If you ever get the opportunity, try to sit in one, especially an early generation one, because it is one of the smallest cabins I have ever been in. The thing that makes me upset though is that I truly feel like the new car could make much more power than it currently does but that Ferrari is holding them back because it doesn't want it to have more power than them.

The problem of the system not being able to keep up with the driver was the major complaint when the feature first appeared on the Stingray. However, I believe Chevy has updated the software so that the system works much faster now, especially on the Z06.

I'm sure it would as long as you are going 4th to 3rd to 2nd and not just 4th to 2nd.

CAcoalminer > scoob
01/09/2015 at 00:13

Yes. In fact, they created it before Chevy.

The video does indeed show it, but it's over-saturated with music that kinda ruins it, but it does show exactly what I was looking for, thanks!

Well tonight just became a nightmare, as I've realized my 944 needs more work than I thought, and I wasn't really looking forwards to doing so soon. I have to do a timing and balance shaft belt change on my car and even though I've got the internet to guide me, I still don't trust myself alone to do this without supervision. I'm honestly very scared to try this, knowing the potential risks with failure. ;_;

Other than that, I start my next semester on Monday, I'm also terrified of that as well.

One of the tech schools by me had one of the original prototype Vipers on display that you could sit in before Fiat/Chrysler decided that even though they weren't being driven, they were still "unsafe" and crushed them all.

I guess it'd be nice in traffic, but on a track it smells like CHEAT MODE.

Nissan put auto rev-matching on the 370Z, too, IIRC.

CHEATY CHEATY CHEATURZ!!!1! J/K, but part of what makes a manual fun is getting the darn shifts right.

Stef Schrader > K-Roll-PorscheTamer
01/09/2015 at 00:19

OOOOOH.

So, we put the sucker on ourselves, but still took it to a shop afterwards to double-check the tension on all of that. That ended up being FAR less expensive than having them do the whole change, though, so there's that. Plus, that saved me an engine because the sucker was on too tight.

K-Roll-PorscheTamer > Stef Schrader
01/09/2015 at 00:26

That's not the only problem though... ;_;

Stef, I'm scared to do or even try this on my own:

This is my thread on the issue: http://www.944online.com/cgi-bin/yabb2/…

This is all disheartening to me.

Now that dual clutch transmissions exist it's somewhat pointless, but during the days of "clutchless manuals" and SMGs, I always thought it would be cool to have a manual that the car could control.

So you could drive it like a full auto or full manual, let a non-manual driver use the stick shift while the car clutched/revved, or (coolest of all) change gears with paddles while the stick slammed itself through the gates. Guess that last scenario could be bad if someone's hand was in the way, but could be lots of fun.

Don't wanna agree with that, but that is totally what's going on. You just know Dodge could squeeze another 200HP out of that V10, but there is no way FCA would let them build what really would be a legitimate F12 competitor for 1/3rd the price.

Because of Ferrari, the Viper must always be a step or two below being a genuine supercar, and that's a shame. I feel like the Fiat merger simultaneously gave the viper what it needed to cross the gap AND every reason for those in charge to stop it in its tracks. :(

That's an awesome feature!

CAcoalminer > K-Roll-PorscheTamer
01/09/2015 at 09:20

You're welcome.

Oh wow. That does seem like quite a daunting task.

What year are you in school?

I'm still disappointed about that. Such a waste of a perfectly good vehicle.

CAcoalminer > PS9
01/09/2015 at 09:31

It is quite unfortunate. Also, I dislike how Ferrari refuses to help any of its siblings. Take for instance the Alfa Romeo 8C. Ferrari could have provided their engine, suspension, or at least the transmission from the 430 Scuderia to that car but instead made them use subpar Maserati parts. The 8C could have been a truly magnificent machine and it wouldn't have threatened Ferrari because it was limited production. Unfortunately, it is now just known as a pretty car and that's about it.

PS9 > CAcoalminer
01/09/2015 at 12:28

I KNOW! And it made zero sense to be so stingy given that Ferrari doesn't even make that kind of car anymore! UGH Ferrari can be so frustrating sometimes.

...I still want one, though.

Roadster Man > CAcoalminer
01/09/2015 at 12:49

Ahh, I see. Do the newer Porsche 7-speed manuals have this feature too? I remember hearing somewhere that they might end up with it.

I'm sure with the right software they can get it to rev pretty damn quick, but I don't see this thing being able to read my mind that I'm going from 4th to 2nd. Oh well, not like I'm in the market for a ZO6 anyway...

CAcoalminer > Roadster Man
01/09/2015 at 13:29

I don't think Porsche offers it yet but I could be wrong.

They might be able to sense what direction you are moving the shifter and make decisions based off of that. I'm not sure though. This technology is a bit over my head sometimes.

Roadster Man > CAcoalminer
01/09/2015 at 13:32

Yeah I could have sworn that Porsche offers it on their manuals too. Maybe there are switched in each gate of the gearshift, so it knows which gear you're about to go into? Technology is crazy. I am thinking of switching my car's ECU to a MegaSquirt... Just reading the online manual makes my head hurt. I can't imagine the technology that OEM's deal with when they invent this type of thing.

CAcoalminer > Roadster Man
01/09/2015 at 13:58

Interesting and yeah that makes sense. Haha I can imagine. These engineers must be geniuses to come up with this stuff.

K-Roll-PorscheTamer > CAcoalminer
01/09/2015 at 22:25

I'm very worried about trying to tackle this job. I haven't even got a lot of tools to tackle this job.

I'm starting my 2 1/2 year at my school, and I finally have enough credit hours to be considered a sophomore. But I'm very low gpa wise, to the point where if I can't get a cumulative gpa of 2.29 this semester, I'm out. ;_;

I have a lot of pressure this semester, and I feel like no matter how much I try or think I'm trying, it won't be enough.

I'm disappointed most of all in the fact that car was 20 minutes from my house and I never got to see it.

CAcoalminer > K-Roll-PorscheTamer
01/09/2015 at 23:23

Geez. I didn't realize it was that extensive.

I'm sorry to hear that but I'm sure you'll make it. From our conversations, you seem to be quite an articulate young man, so I have confidence in you. Do you have a dream job that you will use your degree for or are you still undecided?

I can remember those days. Even though it is difficult, I urge you to keep giving it your best effort. It might not seem like it now, but it will pay off in the future.

Wow that is even more disappointing.

K-Roll-PorscheTamer > CAcoalminer
01/09/2015 at 23:52

I just want to use my knowledge and hopefully what skills I acquire to put myself someplace where I can work with vehicles, cars. I'd rather be working now than having to put up with so much school work.

CAcoalminer > K-Roll-PorscheTamer
01/10/2015 at 00:05

I can understand that. Are you networking with people to see if you might be able to get a car related internship?

K-Roll-PorscheTamer > CAcoalminer
01/10/2015 at 00:11

I haven't networked much really. God, I don't even have a complete resume yet for internships. I can't multitask effectively between classes, work, and resume. Every time I want to work on resume, school and work get in the way, and when I've finally got the time, I'm dead tired to do anything. :(

I've got family friends that can help me with an awesome internship at TRD, but that's pretty much it. I want to have a chance to try at Ford though, I can't do GM or Chrysler for biased reasons and the fact that they seem boring.

CAcoalminer > K-Roll-PorscheTamer
01/10/2015 at 00:20

I understand. Well, when you have time try putting one together. Your consistent work experience is actually a huge bonus to employers because it proves that you are reliable. In addition, work experience combined with decent grades is much more attractive then someone with excellent grades but little experience.

Well, that doesn't sound too bad.

K-Roll-PorscheTamer > CAcoalminer
01/10/2015 at 00:41

I just need to find the work first. Everything seems to be moving so much faster than I can work out and comprehend, it's almost overwhelming.

CAcoalminer > K-Roll-PorscheTamer
01/10/2015 at 01:10

I'm confident you'll figure it out. Just start slow by looking at job postings of the companies that you're interested in and see if any appeal to you.

K-Roll-PorscheTamer > CAcoalminer
01/10/2015 at 01:45

I guess it's more about finding A job, rather than finding the one you want right now huh.

CAcoalminer > K-Roll-PorscheTamer
01/10/2015 at 01:53

Not necessarily. You definitely could luck out and find a job that you absolutely love right away. However, variety is never a bad thing. Like I told my kids and now my grandkids, you don't know that you don't like something unless you try it. Therefore, taking a job now, even if it isn't ideal, may provide you with connections to a job that you make love or, at the very least, broaden your perspectives.

K-Roll-PorscheTamer > CAcoalminer
01/10/2015 at 02:04

You bring up a very true and excellent point, I won't know what job I like until I try it.

CAcoalminer > K-Roll-PorscheTamer
01/10/2015 at 02:15

Exactly.
