Rev Match On or Off

[ctechauto]

To be fair, heel-toe on the streets (normal driving for the most part), you're going to have to practice A LOT to avoid mashing the brake harder than anticipated to heel-toe.

I'm sure if you tried exactly what you're doing on the track, you'd probably do it right and consisently right since you're going to be naturally braking heavier/more than the street.

That last bit does make sense and probably why it stands out more to me.

Bro who are these people that are slamming from neutral to second gear without rev matching it

my god.

@Spart brought math to an opinion fight
Neutral → gear while rolling isn’t “free” — the synchro is literally what makes it possible without grinding. It’s in the name, synchronizer.

Laughs and bickering aside, this is as a good discussion because it brought together a few different perspectives and now we can align. I definitely learned something and the explanation of underlying reasons helps me to better understand my car.

anywho
Size 13 wide here and I can’t heel toe to save my life. I watched that video of homeboy in the NSX and I’ve tried it similar to that before but I end up mashing the brake pedal more than the gas. There is no room for my feet to move. It seems like with practice that transition could get smoother but I don’t feel like I can actually do a successful down shift to build my confidence to keep trying. The I saw I wasn’t the only one and my will left the chat.

Does the Acuity pedal modification make this transition easier for anyone who has similarly sized hobbit feet? Or do I just need to git gud?

Not against auto-rev but I agree with the sentiment I got a manual to be engaged in driving — though I def see the times where maybe you just ain’t about it! So it’s a convenient feature to have, at the very least.

Are U trying with the right side of your foot are are U one of the folks that twists their leg? Never seen it done that way in person but if that’s how you’ve been trying. Maybe try the edge of your foot?

This.

Rev-matching does absolutely nothing for the synchronizer.

Double-clutching is what takes load off the synchronizer.

The more you post, the more it's clear that you don't understand how any of this works, yet you're happy to post things like this:

U don’t know what you’re talking about

shut the fuck up about it

you people are psychotic.

Some Honda people can be so full of shit

I am one size down from you.

You need to learn it in steps rather than all at once. It starts with learning to brake with the ball of your foot rather than your whole foot. It's hard to slide your foot on the brake pedal while applying pressure, so you need to start with your foot placement correct to begin with. You need the right side of your foot to be hanging off the brake and hovering over the edge of the throttle, and you need to do it consistently.

Once you get used to doing that, practice rolling your foot and blipping while parked.

Once you get used to doing that, practice it while you're moving but don't actually shift. Just blip in neutral and get a feel for keeping brake pressure consistent.

Once you get used to doing that, try actually downshifting.

I have a much more detailed post on all of this that I would recommend here: https://www.civicxi.com/forum/threads/how-to-heel-toe-with-big-feet.57620/page-2#post-984644

I did not become a heel-toe god overnight, it took a lot of practice until I got to the point where I felt comfortable doing it at track speed. Quite rewarding though. I gave a fellow track-rat buddy of mine a ride in my GT350 one time, and he commented that he didn't know those cars came with automatic rev-matching. (Narrator: the GT350 does not, in fact, have automatic rev-matching.)

Regarding pedal spacers, I have never used one. I would think that when using the method where you bridge the pedals, as long as your feet are wide enough to do this (and yours definitely are) that they could be a detriment because they often raise the height of the throttle.

I don’t. That’s why I asked people that knew. It sounded like straight bullshit from the very beginning just going off of my experience. A rev matched shift does not stress a synchro

but instead of regurgitating bs. I asked two men that have seen more transmissions than any of us combined.

rev match the shift and it’s fine. U can cherry pick my comments all U want. I don’t care. And homie can hit us with 20 equations that represent nothing but the speed of the car or input shaft or whatever the fuck that was a few pages ago. It means nothing.

All I see is one cat who doesn’t know what double clutching is. Cuz when you’re in neutral. And clutch in. And give it gas to rev match into second gear while you’re moving. That’s literally a freaking double clutch. Which relieves stress off the synchro when rev matches correctly. This is basically the premise and operation one performs when needing to double clutch into gear while coasting in neutral.

and another cat who hates to be wrong and throw math into the mix to…. Do what exactly? I don’t know what he actually accomplished with that except have three forum members text me and tell me how dumb he is after they did their own research.

I was the bigger person first. I said I was wrong for doing it because the two gentlemen I spoke with made me realize. In my native language. How unsafe that was. And how it eats my brakes

but I’m not gonna sit here and pretend the shit y’all are spewing is correct.

but that’s it. I feel like I’ve made my point to the best of my ability. Regrettably I don’t own a vocabulary that will allow me to explain this in such a way that will allow me to continue this in English. Not anymore at least. Y’all have no idea what y’all are talking about. And I will not go back and forth on this anymore.

so I will continue to be the bigger person one last time. I’m done with this topic. Stick the fork in the socket yourself if you want bro. It literally does not affect me if y’all know how a synchro actually operates.

peace be with you. And the other guy

Gmail indeed……

A rev matched shift does not stress a synchro

This is completely untrue and reflects a deep lack of understanding about how manual transmissions work.

You rev match with the clutch pushed in, and while the clutch is pushed in the engine cannot increase the speed of the input shaft. Ergo, downshifting with rev matching does not take any load off the synchro compared to downshifting without rev matching. The synchro does the exact same amount of work.

What WILL decrease the amount of work the synchro does is double-clutching. You clutch in, shift to neutral, clutch out, rev match, clutch in again, select the lower gear, and clutch out. Because you blipped in neutral with the clutch out, you have spun up the input shaft and thus the synchro has less work to do.

You really need to sit this thread out.

That's literally not a double-clutch. That's a single clutch.

If you did that on an unsynchronized transmission, you would grind the hell out of that gear.

Perhaps you should edit Wikipedia and let the entire rest of the world know that they've been double-clutching wrong:

I double clutch when I hit the clutch twice

Guysssss @Spart @apl360

Alright I think this is getting derailed by terminology.

What folks are basically arguing is: “rev matching takes load off the synchro” and that blipping in neutral is basically double clutching.

Correction:

• Blipping/rev matching with the clutch IN doesn’t reduce synchro work — the engine is disconnected from the trans input shaft, so you’re only changing engine RPM.
• Double clutching can reduce synchro work because you blip in neutral with the clutch OUT, which actually spins the input shaft closer to target before selecting the gear.

Rev match = smoother clutch/drivetrain engagement.

Double clutch = less work for synchros.

Can we move on now lol… AI exists no need for more disparaging remarks. Or ill replace both your tire stem caps with tiny dicks

Not the AI response! Next you'll be asked for a 4 page dissertation on what rev matching is and how it works!

Alright I think this is getting derailed by terminology.

What it's getting derailed by is the fact that people show up with bad information and no motivation to learn anything new.

I'm not arguing to argue, I'm arguing because some young guy could show up to this thread, lurking and not posting, and read something like this:

I’ve literally done it like this for over 30 years.

And think "wow, this guy must be full of knowledge!"

The problem is, many people are incapable of judging the facts for themselves despite X decades of experience. They learn something a certain way and virtually nothing will ever move them off that belief. Typically the only thing that can shake them of a long-held belief is when someone they consider to be a trusted expert on the subject tells them something different.

The common thread in their life is that they have an authority-based knowledge system. Many people's entire head canon solely consists of the "argument from authority" logical fallacy.

They are not evaluating facts, they are not reasoning from first principles, there is just what they've been told.

These people are especially useless on internet forums because they just show up and repeat the same bad info we've all heard ad nauseum. And because they operate on an authority-based belief system, when they show up to a forum with a thousand people using it, the number of people on that forum that they'll allow to challenge their beliefs is always zero.

What are the odds that they have more correct information in their head than a thousand other people? That number is also zero.

And for what it's worth, I can also use this same logical fallacy to make my argument:

I’ve literally done it like this for over 30 years.

I don't do that type of thing because the facts can speak for themselves to anyone willing to evaluate them.

When someone gets defensive and starts citing their own education level or experience or their friend's education level or experience, that's how you know they've run out of facts. It's a losing argument.
