Does the F1 transmission shift at different times when cold?

I posted this in the middle of another topic and it got lost. Does anyone know the answer?


While using the AUTO mode, does the computer make allowances for the engine being cold and then shift earlier while warming up? (360)

thanks, Kevin.

 

No. Only clutch operation is affected by engine temp.

 

Hey Brian, if I may pry, why does Ferrari have the clutch operate differently [worse] in the F1 equipped cars when cold? One of the more frustrating features of the system, in my humble opinion, of course.

Thanks,

I agree. I do not really have a good answer for that one but they do make it slip more when cold.

 

Hi,

hope someone can answer these 3 questions for me. I just purchased my first ferrari 360 modena F1. It has 17,000 miles on it and the service book only has the 5K service done from Ferrari.

1 when should the timing belt service be done? i know they say 30K or 3 years but i only have 17K.

2) was thier any factory recalls on 99 and 00 modena ( clutch) throw back bearings?. Starting off in frist gear is really really jerky. DO you think I have a clutch issue?

 

Your first answer is NOW. The car is almost 7 years old w/o a major--get it done. 3 years OR 30k miles--you obviously have surpassed the 3 year mark..

 

No recalls on clutch or F1 system. Recalls are for safety or emission related equipment or failures.

There were several updates to the T.O. bearing parts and software.


It sounds as though you do have a clutch issue and there are several measures that can be taken to correct it.

 

Slightly off topic (but only slightly).

Been wondering, given that everyone says "skip 2nd gear whilst oil is cold" and having driven a few manual 355's and hence appreciating this comment. What is it like in an F1 355, changing into 2nd when the gear oil is cold? Is it a long shift, does it crunch? etc...just wondering.

Also, does anyone know if F1 (or any other flavour of Semi-Auto) has sensors within the box which synchronise gear teeth/mesh for shift timing? Really easy for a manufacturer to do. Imagine not needing synchromesh (weight/power loss/speed of shift advantage)...just a thought.

 

An F1 has 900 lbs of hydraulic pressure at its disposal to shift the transmission. The trans does not have the ability to say no. Cold, hot it gets put in gear and put in gear now.

The transmission is identical in every way except for the type of shifter that connects to it. Syncros do not rob power and weigh very little. The shift speed is not governed by syncros, it is governed by software.

 

I figured it just rammed it in...makes you wonder...thanks for the answer.

Synchro's weigh something (rotational masses in trans saps some power) and take up space, and although they dont physically slow down the shift, you can shift faster than they can sync which kills them. Surely they are only there to reduce the skill required to change gear manually, and as such in a system where a robot changes gear the robot should be able to time the shift so the teeth engage cleanly.

I would have thought a dog box with helical gears driven by an "intelligent" semi auto system would be better than using a synchro 'box. Given what the F1 system must do to the 2nd gear synchro when cold, just thinking aloud - as you do
