Re: car computer

Does any one have a web site contains the circuit diagram for the electronic boards used in the different cars. Also is there is any site talking about automative electronics design.

Re: car computer

Vicent Yang,
although some information might be available through the diagnostic interface (OBD-II interface), you run into problems interpreting the stuff sent on it since no automobile manufacturer will give you the meaning of the sent data.
Sorry for the bad news,
