F-CON iS can control the latest advanced engines. Just connect to a stock ECU with a vehicle specified harness without modification. HKS "F-CON iS" is a piggy-back ECU for fuel and ignition management as well as new features.
Functions for fuel and ignition controls are inherited from the previous model F-CON SZ. In addition to it, function to collect OBD II diagnosis data was added for correction of setting due to stock close-loop correction values when intake/exhaust parts are upgraded or boost level setting is changed.
