Think my car is in KM?

Find one of those measured miles (mile markers) on the interstate or highway and check the odometer. You were probably having so much fun driving her, you lost count of how far you went.

You cannot change between miles and kilometers and, usually, neither can your dealer unless it is FAI.

 

Yup, that has been known to happen. Try again with a mile marker and see what you get. 5280' vs 3280.8' is quite a difference (.621 conversion factor). FAI can fix that.

They repaired my cluster in my 575 are are the best, if not the only ones capable of these repairs for Ferrari electronics

 

I took mine out with the GPS and measured the speed. Then took a trip from a start point in my US car and then in the 360. My distances matched so US. IF more in the FCar then in KM.

 

Curt- Ferrari speedometers usually read fast, but the odometers are pretty accurate, as you discovered.

 

Wells if your odometer is in kilometers then CONGRATULATIONS your car has less than 20k miles
(Btw it is pretty easy to do it with an app like google maps, waze etc to verify it)

Just the cluster. If you look for the colored tachometer threads, there are instructions for removing the instrument panel.

 

What is the 8th character in your VIN? "A" or "B"? Maybe your car is a Euro and the odometer was not changed to miles...

 

I bought a new Opel (a German car) Manta in 1972 from the Buick dealer. Really liked that car BTW.

The first time I took it on a trip I checked the gas mileage, and was surprised (shocked - dismayed) to find it was something like 14 mpg (don't remember the details - so long ago). Then I noticed that the odometer said I had done about 150 miles on the trip - and I had done the trip often and it was something like 220 miles.

So I did the mile marker test and found that 10 real miles only registered about 6 miles on the odometer.

I figured there was some incorrect gear in the system from a kilometer system and never gave it another thought.

 

Most OBD2 diagnostic scanners and programs can access the odometer function and change between the two and even change the mileage itself. Some manufactures let you change between miles and kilometers via the cars entertainment system without tools. Porsche and Mercedes or even Ford in example.

 

Not true on Ferraris, or most cars. If that were true, every used car dealer could change the mileage at will.

 

In 1996 it became mandatory for all cars sold in the U.S. and Canada to have OB-II. The right program you can do anything computer related on the car. Its even easier today to roll back a digital odometer, then an analog from the old days. With the right program you can even start most cars today without the key!

 

Ferrari you'd need their SD2 software to mess with an F355 or 360. SD3 for the newer stuff. Dealers don't like doing it for several reasons.

 

Not true on the Ferraris or most cars we are discussing. OBDII on a Ferrari only gives you access to engine codes mandated by EPA/DOT and will not get you into the instrument panel on any Ferrari or into many other systems (F1, shocks, etc) to make changes that require specialized tools like SD2s and SD3s. Even the SD2 and SD3 will not allow you to change mileage on a Ferrari. Do you really think manufacturers are going to put cars out there where a $15 OBDII tool allows you to change the mileage on a car? Stop trying to pass out bad information.

And we know all about the mandatory fitting of OBDII to all US cars sold after 1 January 1996. That necessitated the change from Motronic 2.7 to Motronic 5.2. Apparently you do not know what that law mandated and what it did not. The purpose was to allow checks of emissions related systems through a common connector.

 

The tool to read the codes can't. But do to OBDII every manufacture has to run software to run every system of the car and send the codes to OBDII. OBDII is the front end, if you have the programmer even a laptop running Ferrari SD2 or SD3 you are now in the through to the back end and can change multiple stuff. Clocking odometers is big business and with digital its even easier today. Its why some manufactures put odometers in the gear case.

 

Just stop telling owners here you can change things on their Ferrari with an OBDII reader when they cannot. Even an SD2 and SD3 cannot change mileage on a Ferrari. All your double talk does not change the fact that you were trying to pass off bad info. Codes for late model Ferraris do go through the OBDII interface, but it takes specialized tools to work with those codes and effect changes.

 

Any OBII scanner can read the codes. The actual Ferrari SD2 can reprogram anything in the ECU, so can the newer SD3. Hence they are around $20k to buy. You replace the ECU, you can reprogram the old mileage into the new unit. The flaw, people can easily change the mileage on the current unit without putting in a new one.

 

The mileage is not in the ECU, it is in a chip in the instrument panel. You have lost all credibility. If you know nothing about Ferrari maintenance, why are you giving advice?
