Patent Images
1. An engine control system for providing electronic control signals to an engine comprising:
- one or more sensors for producing input signals in response to engine operating conditions;
one or more control apparatus responsive to the electronic control signals and operative to control engine operating conditions;
an electronic control unit operative to produce the electronic control signals in response to the input signals based on a set of defined relationships, and comprising a memory, the memory comprising;
a working storage area operative to store the set of defined relationships during operation of the electronic control unit, and a second storage area operative to store the set of defined relationships when the electronic control unit loses power;
a user controller permitting viewing and modifying the set of defined relationships;
wherein the electronic control unit and the user controller enable selective rewriting of the set of defined relationships in real-time without interrupting control operation.
