Reading and interpreting data from a F1 gearbox ECU

Hello,

For a friend who is looking into buying a F430, I tried to read the covered distances per gear from the F1 ECU in order to double check the odometer (showing +/- 17000km).

I have written my own software to read diagnostic info from cars, see http://autos.groups.yahoo.com/group/UniDiag/ and have some experience in reading data from the Alfa Romeo Selespeed ECU, which is more or less equal to the Ferrari F1 ECU as far as I know. For the Alfa Selespeed ECU, I know it is possible to read the kms covered per gear and from what I have found on the net the same should be possible for Ferrari F1.

I managed to connect to the F1 ECU and read data, but interpreting the data is more difficult. I was hoping to find the same info at the same location as with the Alfa Selespeed, but that is not the case.

The data I could read (in hexadecimal format) was:
Local ID = 01, Rcvd data : 02 F1
Local ID = 02, Rcvd data : 01 1E
Local ID = 03, Rcvd data : 03 11
Local ID = 04, Rcvd data : 03 11
Local ID = 05, Rcvd data : 02 04
Local ID = 06, Rcvd data : 00 E6
Local ID = 07, Rcvd data : 01 EF
Local ID = 08, Rcvd data : 0F
Local ID = 09, Rcvd data : 00 00
Local ID = 0B, Rcvd data : 01
Local ID = 10, Rcvd data : 00 00
Local ID = 11, Rcvd data : 00 00
Local ID = 12, Rcvd data : 77
Local ID = 13, Rcvd data : 06
Local ID = 14, Rcvd data : 00
Local ID = 15, Rcvd data : 00
Local ID = 16, Rcvd data : 00
Local ID = 17, Rcvd data : 00
Local ID = 18, Rcvd data : 00
Local ID = 19, Rcvd data : 03 11
Local ID = 20, Rcvd data : 00 87
Local ID = 21, Rcvd data : 00 82
Local ID = 22, Rcvd data : 00 00 A3 5A
Local ID = 23, Rcvd data : 00 00 05 E6
Local ID = 24, Rcvd data : 00 00 53 CE
Local ID = 25, Rcvd data : 00 95
Local ID = 26, Rcvd data : FF 78
Local ID = 27, Rcvd data : 02 98
Local ID = 28, Rcvd data : 00 5F
Local ID = 29, Rcvd data : 02 80
Local ID = 30, Rcvd data : 01 EE
Local ID = 31, Rcvd data : 00 E6
Local ID = 32, Rcvd data : 00 7C
Local ID = 33, Rcvd data : 00 25
Local ID = 34, Rcvd data : 10 1A
Local ID = 35, Rcvd data : 00
Local ID = 36, Rcvd data : FC 74
Local ID = 37, Rcvd data : 00 64
Local ID = 38, Rcvd data : 00 00 00 00
Local ID = 45, Rcvd data : 00 00
Local ID = A0, Rcvd data : 01 C6 00 64 02 E0 00 64 02 F4 00 64 02 E7 02 EE
Local ID = A1, Rcvd data : 02 16 01 05 03 B6 00 EC 03 B6 00 FC 03 B6 03 B6
Local ID = A2, Rcvd data : 00 C6 01 50 01 56 02 21 02 2A 02 C9 02 D2 00 64
Local ID = A3, Rcvd data : 03 2B 02 1F 02 28 02 C7 02 D0 03 B6 03 B6 01 4E
Local ID = A4, Rcvd data : 10 1A 2A 8E 37 86 33 44 25 2C 1B 7B 0C 76 09 2D
Local ID = A5, Rcvd data : 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
Local ID = A6, Rcvd data : 00 00 00 00 00 00 00

Some interesting values in decimal notation are:

Local ID 22,23,24:
hex dec
a35a = 41818
05e6 = 1510
53ce = 21454

Local ID A4:
hex dec
101a = 4122
2a8e = 10894
3786 = 14214
3344 = 13124
252c = 9516
1b78 = 7032
0c76 = 3190
092d = 2349

Looking at the data readout from a F360 F1 ECU and found on this forum: http://www.ferrarichat.com/forum/attachment.php?attachmentid=1078451&d=1264530248read in the thread http://www.ferrarichat.com/forum/showthread.php?t=271781 and comparing this to my data, I think the decimal values shown above are from the
-Pump ON counter
-Pump ON time
-System ON time
-list of the engagement counters per gear

Can anybody confirm this?

My biggest problem however is, that I can not find any data that looks like km counters per gear. Does anybody know where to find this km info? Or what the rest of data means?

Kind regards, Sander.

 

Hello,

According to a Ferrari dealership here, readout of the covered kilometers per gear was only possible for early versions of the F360 F1 gearbox software. For later versions of the F360 and all F430 F1 ECUs, it is not possible to readout the covered km's per gear.
Can anybody confirm this?

Does anybody have a printout of the data that was read from a F430 F1 gearbox? With that info I might be able to understand all data I did read from the ECU.

Kind regards, Sander.
