Designed specifically for advanced engines, the HKS F-CON iS is a sophisticated piggy-back ECU that seamlessly integrates with your vehicle's stock ECU. Installation is a breeze—simply connect it using the vehicle-specific harness without any modifications. This cutting-edge unit builds on the proven features of the previous F-CON SZ model, offering improved fuel and ignition control, while also introducing the ability to collect OBD II diagnostic data. This feature is particularly beneficial when you upgrade your intake or exhaust components or modify boost levels, as it helps fine-tune settings based on stock closed-loop correction values.
