Modificación del performance en el motor de corsa evolution 1.8 CC a través de la reprogramación de cartografías de inyección.

Abstract

The present research project focused on the analysis and development of a reprogrammable control unit implementation in a Chevrolet Corsa 1.8 cc vehicle. The project followed systematic patterns to achieve its objectives and employed a qualitative methodology for bibliographic research to identify the most effective method for performance enhancement. The selected approach involved reprogramming the injection maps without the need for internal engine modifications. The reprogrammable control unit facilitated the connection and calibration of automotive sensors and actuators involved in fuel dosing, as they were compatible with the new control unit. This allowed for the configuration of operating parameters based on voltage and signal ranges, ensuring optimal performance of the engine. Quantitative methodology was employed to gather preliminary torque and power data, which were then compared using statistical graphs. The programming process involved modifying specific parameters during ignition and fuel supply, resulting in an initial startup map that introduced enrichment values for the air-fuel mixture. The stoichiometric ratio was adjusted within a range of 16.2-17.2 to 1, based on temperature, revolutions per minute, and ambient conditions. The final results were obtained through the implementation of the Haltech Sprint 500 system, resulting in an impressive 11% increase in torque and power.
