Total noob mode on, and also I am drawing blanks when trying to search for something on this. I have the following Marelli dash cluster on my Fiat Grande Punto (info from Multi ECU Scan):

ISO code: 32 83 20 04 AE
Drawing number: 51803094
Hardware version: 51011090002
Hardware number: 01
Software version: 04000008315
Software number: 0500

Otherwise I have no clue about the architecture of the thing, CPU, flash / eeporm. I want to know what possibilities I have to reprogram this thing (folks that read the other things I write might know why). And the bin for it, if it exists, would be really much appreciated.
