Scuderia CCM question

That light is going to come on regardless. The dash has no way of knowing what rotors are on the car and the dash only calculates rotor wear there is no actual measurment or sensor specifically for rotor wear. Ambient temperature, vehicle speed, braking G force and time between brake application is taken in by the dash and rotor wear is derived from this information. Unless new software is installed in the dash with the Brembo GT kit the warning light will still come on.

 

Lights have a way of burning out......just saying.....

 

On early F430s, 612s, and 599s, at least, there are two settings in the Motronic ECU, one for steel brakes and one for CCMs.

If you go back to steel rotors, your Ferrari shop must define this in the dashboard ECU with the SD3. This will deactivate the algorithm which calculates the wear of CCM rotors. It's very straightforward and takes only a couple of minutes to do.

 

Stef- I knew you could do that with the F430, 612, and 599, which came with both types of brakes, but was not sure they left the capability in the Motronic DME for the cars, like the Scud and all 2008 and later Ferraris, that only came with CCMs.

I can't swear it Taz but I'm pretty much 99% sure this parameter still exists in later F430's and even Scud's as I don't think Ferrari would have made a specific firmware version of the Dashboard ECU for these later cars. The OP can check it out easily with a SD3 : Dashboard - Parameters Menu - Brake Type : STEEL or CERAMIC.

 

Correct.

You need to get the dashboard clocks reflashed to the firmware that was designed for Steel brakes.

There are different versions for steel than Ceramic. This was necessary because on F430's the Steel brakes where standard when first launched. The version for steel brakes doesn't have the ccm algorithm built in.

When you upgrade your 360 or 430 to CCM's many people forget that the ABS computer and the dashboard clocks (technically) should be upgraded too to the new characteristics of the CCM's vs Steel. If you don't the abs kicks in earlier than it needs to and the wear algorithm won't tell you when the ccm's need replacement - the flip side is you won't get a light so you'd have to monitor it yourself. I.e. take off the brake discs and weigh them. They loose weight. The weight itself is printed on the center bell.

 

Interesting. Couldn't you just measure thickness instead of removing to weigh?

 

Stef, Trev- So the info is in the 8 Mb chip in the instrument panel (2 Mb in 360, CS, 575M, 8 Mb in Superamerica, F430) and not in the Motronic ECU? I mistakenly thought it was in the Motronic.

Stef- Do you have your own SD3 or just easy access to one?

Taz, the CCM wear algorithm is definitely stored in the dasboard Ecu flash. As 360trev wrote, swapping between steel and CCM needs a reflash of the NFR Ecu (Node brakes). The main parameter stored in the dasboard Ecu activates the wear algorithm if Ceramic is choosen.

No, I don't have a SD3 but I use my own personal software and dev tools to access the Ecu's it's experimental but many values can be accessed and reversed (have a master in IT and made a memoire in cipher algorithms but that's already many years ago but still helps today ).

 

Stef- That explains why you and Duram have been collaborating. We have worked together on the 575M, but my chemistry and math have not helped much.

you guessed it right Taz. But Duram is a real master in this realm
