2016 Ford Focus - Tuners & Analyzers

Performance Tuners and Analyzers

One of the simplest and most efficient options to add performance and improve fuel economy to your vehicle is by using an engine tuner. Plug-and-play tuners are designed to be used on nearly any vehicle equipped with an OBD-II port. Depending on the type of tuner being used, they can be used to adjust throttle response, transmission shift timing, check diagnostic trouble codes, and adjust ECU (engine control unit) tuning. Advanced tuners may even come with display screens with a wide range of adjustable engine parameters, such as engine timing or boost. Find the right tuner to unlock the performance in your vehicle at O'Reilly Auto Parts.

Performance Analyzers

Analyzers allow you to see how your engine is performing, and may also allow you to read or clear diagnostic trouble codes. Analyzers are often also known as diagnostic tools, scan tools, or engine programmers. Most analyzers use the OBD-II port under the dash to access the computer, but some models connect directly to the vehicle's wiring harness to program each vehicle system. While most analyzers allow you to see live engine data, many units will also allow you to reprogram, or flash, the ECU tuning and other modules attached to the engine to aid in diagnosing or increasing performance.
