Fuel control system development apparatus
First Claim
1. Apparatus for use in developing and testing a control system for an internal combustion automobile engine, the system utilizing electromechanical devices attached to a carburetor mounted on the engine, sensors for sensing various engine operating parameters and electrical circuitry including a programmable memory having a plurality of addresses for controlling operation of the devices in response to inputs from the sensors, the apparatus comprising:
- a housing locatable about the automobile in a location where it can be visually observed by an operator of the automobile, the electrical circuitry being installed in the housing;
a wiring harness for interconnecting the sensors and the electromechanical devices with the electrical circuitry;
means for selectably accessing an address in the memory, different addresses in the memory containing information relating to different aspects of the system;
means for changing the information stored in a selected memory address and thereby the operating characteristics of the system;
means for visually displaying the contents stored in a selected address so an operator of the system can visually verify the information stored therein; and
means for visually monitoring operation of the system while the engine is running thereby to determine system performance during road tests, performance of the system thus being observable under actual driving conditions.

Abstract
Apparatus for use in developing and testing a control system for an internal combustion automobile engine. A housing is located in the automobile where it can be visually observed by an operator of the automobile. Electrical circuitry is installed in the housing. A wiring harness interconnects sensors and electromechanical devices with the circuitry. A programmable memory has a plurality of addresses which are selectably accessible, different addresses in the memory containing information relating to different aspects of the system. Information stored in a selected memory address is changeable thereby changing the operating characteristics of the system. The contents stored in a selected address are visually displayed so an operator can visually verify the information stored therein. Operation of the system while the engine is running is visually monitored to determine system performance during road tests, performance of the system thus being observable under actual driving conditions.
