HKS AIC Si

Additional Injector Controller

HKS AIC - Additional Injector Controller The HKS AIC III is a stand alone digital fuel enrichment device that is designed to supply, upon demand, the supplemental fuel needed by forced induction vehicles as tuning levels are increased. The AIC is an ideal option for vehicles that require additional fuel, but have factory fuel systems that offer limited expandability.

Supplemental fuel is integrated via additional injectors mounted in the intake stream or on the intake manifold. Useable on factory turbocharged applications or aftermarket turbocharged applications, from 3 to 8 cylinders, the AIC can control up to eight additional injectors for maximal precision fuel enrichment.

Offering the most comprehensive adjustments available, the AIC utilizes two independent fuel curves: boost pressure and RPM. The boost-dependant fuel curve, can be calibrated up to 2.5 Kg/cm of boost in 0.01 kg/cm increments and the RPM-dependant fuel curve has the calibration range from 1,000 RPM to 12,000 RPM in 100rpm increments. Each fuel curve is independent of each other, yet work simultaneously as the two curves overlap, subsequently offering the sum of the two enrichment values at that given condition.

With the multi-color backlit LCD display screen, real-time monitoring of the rpm, boost and injector duty cycle are in plan view for quick reference and adjustments.

An incorporated GCC function, similar to that of the plug-in GCC unit for the VPC and F-CON, allows for minute adjustments at 5 separate points of both the boost and RPM fuel curves. MAP adjustments for tailoring the transition point of the boost and rpm based curves ensure a smooth fuel delivery as the RPM curve supplements the boost curve at higher rpm levels.

A built-in simulation mode will allow the user to perform a diagnostic test run to simulate and monitor injector duty cycle per the inputted parameters. Because the AIC operates the injectors by controlling the current, it can control both high and low resistor injectors.

All these features make the HKS AIC III the most flexible and precise additional injector controller on the market. Vehicle specific AIC pipe kits and universal kits are available to aid in injector mounting.
