2007 599 GTB - CFC231 or CFC301 Gearbox

Does the 2007 599 GTB have a CFC231 or CFC301 Gearbox? My X431 Launch gives me different clutch wear numbers depending on on which one I pick. Would be good to know which one came with the car.

 

SoFast 2 is the CFC231.
SoFast 3 is the CFC301.

All 599's use the CFC301, including the GTO.

 

this is excellent news! My clutch wear % looks a lot better when I select the 301 gearbox! Thank you for your help.

 

% of clutch wear is a computer estimation that can be manipulated. Best to set the PIS, and do the calculation manually.

 

I would love to learn more about this. Do you mind if I start a private conversation on it? I got a X431 Launch that I have been using to help with gremlins.

 

If you must.

 

Actually I found a resource to do this and will share with the community. I do appreciate your willingness to help.

 

The problem with this type of video is that people with no experience tend to not know the basics. He left out one critical part of this process, so following his instructions will create a situation where the car will stall out, and/or not shift at all.

 

Do you mind sharing what critical process he missed so folks on this forum can be informed?

 

Changing the PIS value has no impact on the clutch wear reading.
That's not how the system works

 

On X431 the direct reading of the wear is not always good.
It must be calculated manually from the current close position of clutch bearing and the close position at new.

I never suggested that the PIS value had anything to do with the clutch wear. All I said was set the PIS (which is normally the cause of severe clutch wear), and calculate the clutch wear manually instead of reading the % the computer estimates.

 

Do you mind sharing what step was missed from the PIS setting video?

 

IF you want your F1 to perform properly and run without issues PLEASE do not try to service it based on video. The F1 is a very complicated system and it has a BUNCH of nuances. I have seen this happen in the 360/430 world and it doesn't go well. People think they can do this and it looks like they did. A few months later there is another thread about how the transmission and/or clutch isn't working correctly. From there, they are down the rabbit hole. Meanwhile back with people who used a mechanic who really knows the system, years have gone by and the system works perfectly.

 

How do you become "a mechanic who really knows the system"? I completely agree that having a good mechanic is worth its weight in gold, but I consider myself competent and I really, really enjoy working on my car. In fact, I love it. Do I have to serve an apprenticeship under said mechanic before I can (correctly) service my own clutch and transmission? If it really is a case of "this job absolutely MUST be handled by a Ferrari-trained professional tech", then I would certainly take that under consideration before diving-in. But I would like the option to do this job myself, is that possible? How do I learn?

 

Fair question and thank you for not taking great offense at my comment. A few suggestions on where to start:
1) There are several threads on here that are very technical, read through those and you will soon see who the really knowledgeable people are. Don't get me wrong, for this kind of work I take my car to someone who know the system inside and out. Note: the 360/430 system is similar in function so you can learn from those as well but it is an earlier generation and a single plate clutch so there are some differences.
2) Find a great mechanic and build a relationship. They will answer questions but they aren't there to teach you everything they know, and they won't even try. Use them for some stuff so they make money and they will help.
3) There are a handful of diagnostic tools good enough to do this kind of work but the list is short. Get one and/or have access to one.
4) You will likely need help from someone at Ferrari, that could be FNA or the factory. Some of the codes are not mapped and you can only get the info from the factory so build strong relationships with someone there.
5) The SW is designed to work with the system as built so swapping in alternative parts/materials can cause unpredictable results.
6) Learn all of the sensors that have an input to the F1 system. These are often the culprit in issues but can be hard to diagnose.
7) Don't trust most dealers to do it correctly. I have had several bad experiences and a good/well known independent is a better bet.

That will get you started. I can tell you from experience that a properly set up 360 doesn't need the PIS adjusted more often than maybe every 5-6 years (I had it ~13 years). I have had my 599 for about 4 years and the PIS has never had to be adjusted. Also, most people set the PIS too tight and it causes other shifting issues.

 

Thanks, John. All of that is very good advice and I can see that we think along the same lines. "Technical" is what I do (yep, I'm a nerd...) and learning the F1 system is an interesting new challenge that I am really looking forward to.
