F1?

According to the links Michael has posted, they state the system does rev match. Seems like this topic is fairly complex.

 

Dave
If people would just do a google search you will find alot more links saying the same thing.
I could post more links but whats the point.

 

Here's what the article says:

There is more. Down shifting is done in the traditional fashion with a double declutch with an automatic blip of the V8 engine in between at neutral to match the incoming gear’s rotational speed with the rest of the transmission just like an expert heel and toe. Makes you look so good every time without fail.

This is 100% pure bs. It goes on to say that the 355F1 has launch control. If it does I never figured out how to use it. Maybe mine was defective because it didn't rev match or have launch control. Or maybe the factory trained mechanics on the board and the ones who worked on my car were wrong about how it operates? Oooooor maybe some people here are just being weird about this.

 

Makes the most sense.

 

Interesting read. Thanks for posting the article. Beautiful F1 used in the test.

 

Maybe you should read the article again...where does it say it has launch control?
What it does say is that the launch can be tricky for wheel spin depending on how much gas you give it.

 

"Random guys"?
Could you be any more deliberately disrespectful?

I guess so, considering you then go on to horribly misrepresent everything we've just spent several pages trying to clarify.

Are you a journalist, by chance?

 

Don't know whether to find it disrespectful or amusing.

Find me a properly maintained F1, original and running perfectly that doesn't blip and we'll be talking. Ownership experience and in-depth engineering analysis I respect. Mere opinions need to be fundamented. Namecalling doesn't get us anywhere. Proof does. I can provide proof that mine is working 200% right and blips everytime as it is supposed to. Can you prove it doesn't?

Best regards,

Nuno.

 

This thread not only applies to 355's , 348's rev match too on downshifts , but its not just a blip , its a full on match , just like a 360.

My throttle blips on my 3 pedal when I execute the perfect heel and toe. Bloody amazing

 

Please do, it would be enlightening.

 

I'm talking about the f1 in my f348f f1ff

You are wrong. It's not possible. You must be hearing things.

 

Are you telling me i dont know my car , i'm not hearing things . Who are you to tell me ? Why are you even participating in this discussion , you dont have. a f348f f1ff . The fjv valve opens the phy solenoid and activates the sdj resulting in a perfect counter active rev active rpm dismatch.

Even more important , is my f348f f1ff worth more than the manual clutch 348's ?

John, I believe Steve was being ironic. That's exactly the kind of reaction we get when people say our F1s don't blip.

Cheers,

Nuno.

 

They blip ? That happens to me too when i eat spicy food .

Morning All! (even though it's evening here)

I just remembered that a good friend of mine recently gave me several boxes of old motoring magazines (he has a collection which goes back around 35 years), all in "only read once" condition.

Anyway, I happen to have a Motor Magazine from 1998, which happens to have an article on the 355F1.

Read away (I haven't included the 1st page due to file size which was just introductory anyway), but the highlights in relation to this thread are the discussion of the max performance start (which could be considered to be the forerunner to proper modern "launch control" but there's no way I'm going to use those words on here), and the following quote:

"...But it's a game with real mechanical feel and precision, from the perfectly timed blips on downchanges, to the slight lift-off the throttle needed during upchanges in lower gears for the ultimate in smoothness...."

Actually, the word "blip" is used twice in relation to downshifts

355 F1 use. A few place in the video you can hear it, particularly 5.0

Nice one Dave.

 

Thanks steve that was a good read
Did you read the links that i added in posts #148 and #150

 

Thanks to both Dave and Steve for setting the record straight.

That's the end of it, imho. I know that Dave and Steve, like myself, if they had encountered any information stating that the F1 doesn't blip and they were wrong, they'd be the first ones to admit it. I myself had to reconsider on one or two occasions strong beliefs I had prior to digging information up, and I did so gladly. That's how I learn.

On the other hand, when you're right, you're right. As a consequence, when you're right, proof always emerges abundantly, as in this case.

Kind regards,

Nuno.

 

I have. Thank you Michael. The evidence is mounting, and it's all one way.

You are right, Nuno. Although it would be hard to dismiss what my ears were already telling me, I would have accepted it if it turned out I was definitely wrong.

I'm expecting soon that some of that legendary humility will be on display from the posters who ridiculed us for simply posting what we have observed, but it has become awfully quiet around here compared to a couple of days ago...

 

Since I am a mechanical engineer and just overall technically curious, I really wish I knew EXACTLY what the system is doing - from a ECU, technically stand point. It would sure be nice to monitor all inputs and outputs at the time the downshift lever is pulled.....

 

Watched this about 10 times at the 5 minute mark and didn't hear anything resembling rev matching or throttle blipping being completed by the car. The revs go up, but that's what will always happen when you switch to a lower gear in any car with any transmission. He might be using his foot to match revs but this video doesn't in any way indicate that the car is magically blipping the throttle with some unknown source.

As for the PDF articles posted, here's what it says:
First it checks to see if both car speed and engine speed are right to make the gearchange. lt will not permit a change that over-revs or makes the engine labour.
Second, it evaluates engine torque. This point here is to avoid slippage and possible overrvving when the clutch is opened.
Third, it disengages the clutch.
Fourth, it takes a look at what the engine is doing and provides rev and torque targets before making the shift.
Fifth, it double checks that the change is complete.
Sixth, it engages the clutch.

Step four is where the 'blip' would happen. What this says is that it merely checks to see where the revs will be when the clutch is re-engaged, I presume to make sure that it won't shoot up to something like 12k and grenade the engine.

No but I find it humorous that you accuse me of being a journalist when I'm quoting the words from a factory trained Ferrari mechanic who has probably worked on hundreds of 355s, and you refute his input by posting quotes from a magazine article written by a journalist

I'm not trying to be ****** here but after seeing the responses I understand now why people like Rifledriver quit the forum or get banned for "being mean" every 2 months. I put over 42k miles on my 355F1 over 8 years and it never once blipped the throttle. If you have your foot in it and downshift, the revs will shoot up a few hundred RPM when the clutch is disengaged but that was described pretty eloquently in post #30. When I bought my car, the salesman at Ferrari of Denver told me it doesn't rev match. The factory trained mechanics that took care of my car who have decades of experience working on these told me the same. Another factory trained mechanic who is extremely generous with his free advice on the board is saying the same thing. But apparently a magazine article that says the 355F1 system actually rev matches "makes this more complicated"... The level of misinformation in this forum is pretty staggering, which is the only reason I bother getting involved in these little chats, as frustrating as they are.

I kind of remember reading something a few years back that it has something to do with the TPS the rpm and the ECU.Thats why i posted why does an F1 car have a different TPS.
