Performance Chips and Programmers
The performance chip (also known as power programmer and performance programmer) works as a replacement for an ECU (Engine Control Unit) chip that holds an engine's lookup tables. The aforementioned tables found in the performance chip contain values that translate to higher fuel rates during certain driving conditions. For example, the new lookup tables may supply more fuel while at full throttle and at every engine speed. The spark timing may also be altered as a result of this. Since manufacturers of performance chip makers are not as focused on issues like reliability, mileage and emissions controls as the car-makers are, they tend to utilize more aggressive settings in the fuel maps of their performance chips.
