PPC, I read a bit on the HKS S-AFR, sounds nice but i don´t think it would work with our cars, it does not support flap sensors.
The HKS Super AFR is the very first airflow meter correctional device in the industry with a built in CPU. The advantage of having a built in CPU is that instead of making corrections to the airflow meter voltage, the characteristics of the airflow meter is inputted in the CPU so it can calculate the most accurate amount of air flow. Since the correction will be made to this specific intake volume, the correction ratio of fuel will be precise and proportionally correct.
The Super AFR is compatible with virtually any fuel-injected Import or Domestic, 12Volt, 2-12cylinder vehicle that utilizes a hot wire, Karmen Vortex, or pressure sensor. The internal CPU allows it to be versatile and be utilized on many of the newer type airflow meters. Also incorporated in the Super AFR is the ability of idle air/fuel ratio corrections as modification progress and require further specific tuning levels. The response function, similar to the one in the VPC, allows for adjustments to the fuel settings upon throttle inputs to improve driveability and performance.
The EIDS function is automatically programmed with the data from the initial self-learning calibration and is automatically activated to correct sudden imbalances in air/ratios from discharge valves upon deceleration.
