F1 overhaul thread; clutch, pump, throwout, flywheel, 360 pump etc.

They had no problem using the SD on it. I verified every signal into the TCU related to entering self learn and they were fine. I am tempted to try a self learn now, in the name of science, but will probably let sleeping dogs lie and enjoy a working F1 system. There certainly seems to be a division in cars that self learn triggers in and cars that the owners just can't trigger it.

 

It worked great for a while (sat idle allot due to work) but two glitches came up but are resolved.

Problem #1 really pissed me off. I had Ferrari calibrate the F1 system after all the work detailed in this thread. It was OK for a while but what I discovered when I started having gear engagement problems was pretty sloppy. They installed a longer bolt with the bolt threads facing downward, it probably had a tiny amount of clearance but once the motor mounts settled it started hitting the cross member. I turned the bolt around and huge clearance was gained. How F'in sloppy can you get for the price they charge.

Problem #2 was developing as problem #1 was worsening just by dumb coincidence. The pulse generator was failing and failed all together which made the problem easier to zero in on. A new one was ordered from Ricambi and was installed today, When I pulled the old one a hairline crack was very visible on the face of the sensor. It doesn't show up much in a pic but it is there once you see it.
The car behaves very well and is back in action. The more I learn about how the F1 system works on our cars the more inspired I am to move past the SD dependency.

The F1 impact from the failing/failed pulse generator is that when it fails the TCU locks you into 1st/2nd/N/R and a flashing trans light.

Yes, the speed sensor mounted on the driver side of the transmission.

 

I thought I would share the latest work. After about 8k on this clutch I did a few years ago (and the F1 system working very nicely other than the failed pulse generator) I started getting the worn clutch alert and noticed a few slips so I knew it was time for a new clutch, but why so soon?

****A bit of relevant background: When I had the original fault(s) that resulted in the new F1 components and new clutch one of the problems was the clutch disk being contaminated with trans fluid. It wasn't slipping or worn unevenly but it wasn't in good shape, this was the second clutch that the car had seen and was installed before I owned it. I replaced the clutch disk with a relined one and resurfaced the flywheel. The pressure plate was flat and had no odd wear patterns. I used the OEM Ferrari triple seals and O rings.

I got it up on the lift and took it apart and found that the clutch disk was worn very unevenly with the side facing the flywheel having aggressive wear and the side facing the pressure plate wearing normally, however the flywheel is fine but the pressure plate is dished. I guess the disk flexed because of that creating an opposite wear pattern. Odd, but the flywheel is fine and the pressure plate is certainly not. So the pressure plate dished since the new clutch went in, which is a known failure of these clutches. Typically the triple seals leak, the disk gets contaminated and slips, and the heating warps the plate. There was some fluid leakage and it was coming from around the triple seals which were intact and undamaged, but the disk doesn't seem to be contaminated like it was last time. This time I ordered the Viton triple seals from Superperformance instead of using the OEM ones which have leaked twice on me. I have a new clutch disk, pressure plate, and all the seals and O rings on order and will get it buttoned back up when they arrive, then go get it calibrated.

The new clutch/seals going in and the end result have got to be the smoothest experience yet with the car! Everything just slid into place with no difficulty, the viton seals were a joy compared to OEM. The stock seals remind me of that ring left on a soda bottle after you take the top off, the viton ones installed with no drama and fit in their grooves much more snugly. I performed the self calibrations before taking it for a short drive to make sure it was OK to drive to the shop for a proper SD calibration. The clutch engagement and shift behavior of this car has never been this awesome in all the time I have owned it, engagement is like magic and it is so good I almost don't want to let anyone change a thing in calibration. I know I HAVE to so that the clutch wear can be reset to 100% so everything continues to play together well......

 

I took the car in today to Loudoun County Exotics in Sterling VA and had them do a post install and reset of the clutch wear data and everything went perfectly. The car is shifting perfectly and the data looked good. These guys are a great resource and quite reasonably priced as these things go. What really impressed me about them is that they had no problem with me watching over their shoulder and seeing how each step went. I am not interested in the couches and coffee of a waiting room, I want to see what they are doing and how. I got another good up close look at the Leonardo system and how it plays with the 355F1 and learned quite a bit.
