1. A method for controlling an internal combustion engine in a motor vehicle having at least one microprocessor, comprising the steps of:
- storing at least two data records in a first memory device, each of the data records having an identifier, including a coded bit pattern for marking an identity of a data record, stored in a same predetermined relative location within each of the data records; and
controlling the internal combustion engine as a function of the data records.

18. A method for storing and retrieving data records, for controlling an internal combustion engine comprising the steps of:
-
storing at least two data records in a first memory device, each of the data records having an identifier, including a coded bit pattern for marking an identity of a data record, stored in a same predetermined relative location within the data records, each of the data records further having at least one engine control variable stored therein; storing a selection value in a second memory device; comparing the selection value to the identifier stored in at least one of the data records; retrieving the at least one of the data records when the selection value matches the identifier stored in the at least one of the data records; and controlling the internal combustion engine as a function of the retrieved at least one of the data records. - View Dependent Claims (19, 20, 21, 22, 23, 24)

25. A method for controlling an internal combustion engine in a motor vehicle having at least one microprocessor, comprising the steps of:
-
storing at least two data records in a first memory device, each data record occupying a distinct and contiguous set of memory locations; storing an identifier in a same predetermined relative memory location of each data record; storing a selection value in a second memory device; selecting a matching data record using the selection value and the identifier stored in the predetermined relative memory location of each data record; and controlling the internal combustion engine as a function of the selected matching data record. - View Dependent Claims (26)

27. A device for controlling an internal combustion engine in a motor vehicle comprising:
-
at least one microprocessor; a first memory device for storing at least two data records, each data record occupying a distinct and contiguous set of memory locations and containing a same predetermined relative memory location for storing an identifier; a second memory device for storing a selection value; the at least one microprocessor being adapted to select a matching data record using the selection value and the identifier stored in the predetermined relative memory location of each data record, and to control the internal combustion engine as a function of the selected matching data record. - View Dependent Claims (28, 29, 30)
