360 Problem with upshifting from 1st to 2nd gear

Did you run a relearn ?

 

just to be sure .. which function did you use and what diag tool do you have ?

 

So you are using the gear box relearn under the "special functions" under gearbox menu ?

While doing relearn does it go thru all the gears and finish successfully

How about contacting the person who did your CS controller upgrade.

 

Try bleeding clutch again from both top(near frame) and block (near clutch)

Did you record the clutch configuration data and P.I.S data from your old TCU, and input those parameters into the new TCU? If not..do that then redo the self learn.

 

Did you perform a clutch configuration and input the original new clutch value into the new TCU? Keep in mind that the new clutch position should be between 14.2-14.8 and that the PIS on the Stradale will be much more sensitive. If the PIS is to tight the clutch will drag and you cannot get into second if the input shaft speed is not where the TCU wants it to be. I would suggest you configure your new clutch position to your current clutch value even though you will lose your clutch wear. You can manually calculate that later.
Then adjust your PIS correctly. 4.2 works pretty good as a starting point for the Stradale. Most people set the PIS to tight thinking it saves clutch wear, it does not.
I suspect your PIS is to tight for the aggressive Stradale software and it is waiting for the input shaft speed to slow down and when that doesn't happen it goes to 3rd as the input and output shaft speeds are close enough top mesh. common issue.

 

The CS TCU updates I have performed for several clients have come with a set up in the TCU. It is not what the current car wants and I have had to change the clutch setting and PIS to what the current car wanted. Sounds like that is what you need to do. I am sure you can work it out with setting changes to get the TCU the parameters it needs to function well. I haven't had one not work yet. My provider even sent one that another client was struggling with and I was able to dial it in on a car I had. That still won't let it function for the other client because his car likely wants to see something different. It just confirmed the TCU was not an issue.

As I was told, you basically have a copy of a CS TCU with all of the data/parameters that car was using. Your car will want its own data/parameters to function well. Self learn will not get it all, that just lets it learn where the shift forks want to be for the hydraulic actuator. Put in the clutch as a new clutch and see what happens. You will loose clutch wear but I make notes in the file as to what the clutch wear was before and make the client aware of this.

 

If you set it up as a new clutch, it will learn where everything is and it may not be 18.53. It will set the clutch wear back to zero or very close to zero when you do this. If you adjust PIS afterwards it might make the clutch wear move. This will give you the best performance.

 

Wade: What is considered normal procedure.?
Clutch replaced as in OP's situation-Immediately before driving set new clutch position and PIS.? or a bit of clutch applications [short drives] set new clutch and pis..?
There has been a few who have clarified this but its all not the same.
Thanks for sharing your expertise with all of us.!

 

According to Ferrari ..bedding in a clutch before setting it up is preferred

Working with a few people replacing clutches here ..that is what we did

Cycle Test function on SD2 has been a very valuable diagnostic tool. If your machine has that test try it.

 

I set it up when I am finished and drive it to bed it in. I want optimum set up from the start and I may do another set up after the bedding in if it needs it. Usually it will be good after the initial set up and bedding.
