Every ecu has a sticker on the side with various bits of information. The string we are concerned with is a string that fits this format: LLN-LNN, where L is a letter, and N is a number. The first 3 characters will tell you the ecu family, and the last 3 characters will tell you if the ecu is manual or automatic. Generally, ecu's which are manual will have a range of characters starting with -A00 and going to -A49. Autmatic ecu's will be greater than or equal to -A50.
