Look like about 23 percent Image Unavailable, Please Login

And yes ev08 is for 2008

I just found that thread also. The interesting part is that I recall my mechanic saying my clutch was actually just shy of 19% (he rounded up to 20 when he wrote the PPI report up). If you use the incorrect 7mm wear formula that is referred to as wrong in that thread my clutch is right around 19%. As I don’t think I burned 4% of clutch in less than 300 miles of normal street driving (no track, launch control or reversing up a hill) so my mechanic must have one of the computers with the wrong calculation of 7mm vs 5.6mm (or the calculation is right for an 08/09 and we have been using numbers from the 05 thru 07 cars).

Now that I have a way to track the wear, I’ll start a spreadsheet and keep an eye on how it goes as I put mileage on the car.

Cheers,
Corey

 

maybe I can't see the formula correctly due to it not being clear ....but I got 20.06 with the numbers you posted. Is 23 percent correct?
Could you list the thread that discuss this?

Thanks,

 

The formula is. Difference of both position divided by 5.8 times 100

Oh...ok it was hard to read..i used 15.6 as the denominator.....but still got 53.96
3.13 divided by 5.8 x 100 = 53.965

 

18.425 - 17.119 =1.306

1.306/5.6 equals .2251...*100= 23.3percent

My prior posts used 5.8 should be 5.6

One more thing. just thinking... The 5.6mm quoted in the other thread was from Maserati. Are we sure the 430 is the same? maybe 7mm is right and the x431 uses the right calculation for ferrari but is wrong for Maserati?

 

OK...there was the confusion. I used the pick you posted and not the numbers from CoryNJ.

...sorry.

Thanks!

 

From the SD printouts I have seen for a f430.. 5.6 looks like the number it uses for that vehicle

Can you do everything included in a service schedule with a x431? 430 that is. Can you flush the F1-system also?

 

I found a screenshot of the original PPI on Feb 28th. It was even better than I remembered at 18.07% and the numbers do add up to using 5.6 as the max wear number. So I started another thread about "Avoiding Clutch Wear" because I'm obviously driving the car wrong. Hopefully I'll get some good tips here and going forward monitor my clutch wear myself.

Cheers,
Corey

 

You are correct if it works as described... I will give it a try. What is $330 and where do I buy it?

 

Hey guys, I just received my AP200 from Amazon earlier today, and I started playing with it on my 2006 F430 F1. First off, the report generated from the software does seem to provide the clutch wear index in %:

Let's just there were a lot of other things flagged, but it's not clear what's historical (I had some issues with a low battery):

The stuff in the green circle is concerning. Can I assume that my F1 accumulator is having issues? My independent shop recently checked out the F1 system (plus flush, etc.) and didn't find an issue.

 

Are you seeing / feeling any issues ?

lot of those seem voltage related ..low battery in start


If everything seems ok .print the complete list and see if there is any freeze frame for each ..print that then.check / charge / replace battery and then wipe codes out .. drive a bit ..close open too etc and then check again

Not sure if the ap200 have freeze frame capabilities

Hey Dominick, thanks for the quick response. I did have a low battery state ~1y ago, but that was resolved. What prompted the recent trip to the independent shop re: the F1 system was that when I tried to start the car ~2 mos. ago, absolutely nothing happened (to be clear the car was clearly on and I tested the headlights, which seemed to work just fine). There was, however, a light for the F1 system (the weird engine cover looking thing), but nothing on the screen. I did a battery disconnect and reconnected (perhaps too soon), and tried starting again, and seemingly every error message re: the F1 that was possible flashed across the screen. So I disconnected again, waited for a good minute or so, and reconnected and the error messages disappeared and the car started right up. I took the car straight to the shop from there, but over the ~20 mile drive, there were absolutely no hiccups. The mechanic did a lot of diagnostics and did note that the F1 computer had become disconnected from the main ECU(s) at some point. Beyond that, he couldn't find anything. His comment on the phone, spoken in a thick Italian accent, was that "...she's like a woman. Some times she loves you; sometimes she hates you." ;-)

 

Oh, and the battery was tested, and it's fine.

 

Ok all that makes sense .. I would clear all the errors with the ap200 after printing and see what come back .. then report back ..we can go from there

Thanks again! Will do

 

Also btw did you follow the battery reset procedure when you discontinued the battery ...in the manual ..resets the system properly.. by now it may have happened anyway ..but that is something that should be followed when you disconnect the battery

Rereading your pass error ..it light and no start ..could have been the rear latch not recognizing it was closed and giving you the light with no start condition

Hi Dominick, I did do the reset process when the car did start up prior to taking it to the shop (in part because I wanted to make sure nothing screwy happened before I got on the highway), and I'm certain there were other resets done as part diagnostic process. Re: the rear hatch, is was actually the warning light (which I believe pertains to the F1 system), not the engine compartment lid open graphic in the multi-function display. That said, I had to read up on the warning light, as it really looks like it should be about the lid.

 

I just received one in the mail and tried it on my 2003 360 Spider.

There are 2 gearbox options. Marelli Semi Automatic Gearbox System CFC231 and F1 Gearbox System 201 (There is a First and Second edition. Only the Second edition worked)

The Marelli system didn't work. Says N/A for all live data.

The F1 Gearbox System did work, but it doesn't give a clutch percentage readout. I found an article that said to use these two parameters to determine clutch wear:

1. Self-calibrated closed clutch position
2. New closed clutch position

You take #2 divide it by #1 times 100. That told me my clutch is worn 69%. That sounds about right as my mechanics computer showed 63% about 2,000 miles ago.

 

Calculation of clutch wear percentage for Ferrari 360/430:
Autocalibrated closed clutch position - NEW closed clutch position / Clutch thickness (8.5mm for 360, 5.6mm for 430) *100 = % wear on clutch

Guys wear calc was discussed in detail from post 49 .. just scroll back
