HKS EVC 4 PRO Boost Controller

Used Boost Controller by HKS.
Includes the controller, solenoid and wiring harness. You will need to purchase a few lengths of piping to run back and forth to your wastegate/actuator and minor mounting hardware.
A direct quote from HKS "The most sophisticated microprocessor and
adjustment valve available. The EVC IV provides immediate push button selection of preset levels of boost pressure, plus a return to
actuator controlled boost by switching the unit off. All boost
selections and adjustments are accessible form the cockpit of the
vehicle, which gives the driver the ability to change boost pressures
"on the fly." Aided by "fuzzy logic," the EVC IV also has the ability
to learn your vehicles boost curve to reduce as much turbo lag as
possible without over-boosting." end quote. The solenoid is mounted on the engine side of the fire-wall and connected to your turbo waste-gate. The solenoid is connected by the harness to the control unit which is mounted close to your driving position.
