Hks evc 4 setup

The EVC V is a user-friendly, full-featured digital electronic boost controller that utilizes a precision "closed-loop" boost regulating stepping motor.

Stepping motors are used because they can handle higher boost levels and are quicker to react to various conditions, thus offering quicker boost response and higher stable boost levels throughout each gear. The HKS EVC V can correct the signal to the wastegate several times each second, thus allowing a more rapid boost rise without overboosting. A built-in "Fuzzy Logic" program will learn the base boost curve and optimizes it for maximum response and stable boost.

The boost pressure may not go up to KPa because of the specification of the wastegate spring or the capacity of the turbine or the engine.

If the boost pressure is increased more than the normal, the vehicle's boost-cut is activated by the fail-safe system. In that case, use a boost cut cancel device such as FCD. But settings using a fuel increasing device is required to prevent engine knocking, detonation, etc, that may result in engine damage.

A lower gear driving and a high gear driving has a different driving load; therefore, the boost pressure level is different. Please set the boost pressure with EVC at a high gear such as 4th. Check the piping and exhaust bypass switch setting. If the stock max boost setting and initial boost setting are the same, the boost pressure cannot be controlled since EVC cannot recognize the boost characteristics properly.

Check the initial setting values using Easywriter. Both the meter and EVC must take the pressure from the same place. If the difference of the EVC and meter is within the 10kPa, it should be within the tolerance range. To prevent the oil from entering into the valve unit, the air filter is required.

And, if dirt built up is noticed, change the filter. Depending on the certain specification of vehicle, turbine or actuator characteristics, the boost pressure sometimes drops at a high RPM. EVC can control the boost pressure drop to same extent, but upgrading other parts such as an actuator may be required. Surging tends to occur with the recent turbocharged vehicle models.

Map function prevents surging; however, surging cannot be stopped completely. Upgrading other parts may be required. It could happen because of the certain specification of vehicle, turbine or actuator characteristics and etc.

Then you might replace or modify parts to fix it. The screen is the most visible when looking from the front. The screen could unclear pale because of the angle.

Please adjust the angle of the monitor for a best view. The "Data Lock" function may be on. Turn off the data lock. Follow the instruction in the manual to do so. Check the exhaust bypass selection switch is matched with vehicle type. Also, check the short-circuit, wire disconnection, miss-wiring, etc.

Set the MAP function. It will display signals in the MAP function with Map axis. The signals set as the map axis should be displayed. This can control the boost pressure more precisely.
