Hello I have a BMW E36 series saloon version and I would like someone to help with the following question. I know that there is a laptop program that reads and/or changes the ECU values and information, and there is a proper cable to connect the laptop to my car. I donít know where can I find or acquire freely this program, and the cables/connectors scheme so I can do them myself. I donít know either where is on my car, the connector that allows this kind on connections. Can anyone help me with this? Thanks a lot in advance!
