Remapping or chip tuning your KIA involves downloading the memory chips in the Engine Control Unit (ECU) responsible for storing instructions about how your engine runs and changing the information stored there. This memory is the major element in the operation of all digital devices. In the past, auto engines used mechanical methods to make performance-enhancing adjustments, but modern vehicles utilize on-board electronic diagnostic procedures. During remapping, your KIA 's diagnostic technology reads the data stored on the ECU chip and makes changes to improve the vehicle's performance. The data is accessed through the OBD/OBDII port. Remapping can be done on KIA models dating from 2000.
Chip tuning is a similar performance-improvement process designed for pre-2000 models. Both procedures can improve your KIA 's engine performance significantly by enhancing torque and mpg. After chip tuning or remapping, your vehicle has more power and a smoother ride. For pre-2000 KIA models, performance tune-ups are accomplished by chip tuning. This requires removing the ECU to access the memory chip and then reading the data stored on the chip and making changes that will improve KIA's performance, giving you better fuel economy and more power.
