Show original supplier description
The APEXi AFC Neo (401-A917) is a versatile piggyback engine tuner that allows for precise air-fuel ratio adjustments. It functions by modifying the airflow meter signal, and on certain vehicles, the pressure sensor signal, enabling a tuner to increase or decrease fuel delivery at up to 16 distinct points. This capability is crucial for optimizing engine performance and efficiency. This unit also incorporates VTEC control specifically for Honda and Acura applications, adding another layer of tunability for enthusiasts of those brands. While it is designed with universal fit in mind, adaptation to specific vehicles may require custom work or professional installation. Heeltoe Auto advises consulting with them if you are unsure about compatibility with your vehicle. It is important to note that this item is discontinued and no longer available as new. The AFC Neo is a "universal fit" product, meaning it is not manufactured for any specific car model. Adaptation to different vehicles requires custom installation or modifications. Heeltoe Auto cannot guarantee this part will work for every vehicle and recommends contacting them for advice if you have any doubts.
