HKS EVC4 -ELECTRONIC VALVE CONTROLLER
Tested and in working order
This item includes the controller unit, solenoid, and wire harness.
The EVC IV can be used on both internal and external wastegate type turbochargers.
The EVC IV is not capable of reaching boost levels lower than stock (OEM) levels.
The EVC IV will maintain it\'s programming even if the vehicle\'s battery is disconnected or the head unit is unplugged.
The serial numbers must match on the controller and the stepping motor in order for the unit to function properly.
The EVC IV is a sensitive electronic component and must be handled with extreme care. Miswiring or shock will damage the unit. Do not place near extreme heat, water, or areas prone to dirt and dust. Most factory turbocharged vehicles come equipped with a secondary boost limiting system (fuel-cut system or pop-off valve) to safeguard against wastegate failure. Due to this, the EVC IV alone will not be able to raise the boost pressure beyond the point of the factory limit. If this condition occurs, consult your HKS distributor for information regarding products that can assist in this situation (HKS Fuel Cut Defencer, HKS Vein Pressure Converter, HKS Programmed Fuel Computer, etc.). If the vehicle has a fuel cut defense system such as the HKS FCD, make certain that the vehicle\'s boost pressure is not raised excessively, as this will lead to engine and/or turbocharger damage. HKS will not warranty any damage caused be excessive boost levels. Make sure the vehicle has a proper fuel management system that can handle higher boost pressures than stock (OEM) levels. HKS will not warranty damage caused by improper fuel management (lean air/fuel ratio). The EVC IV cannot control boost pressure above the maximum efficiency point of the turbocharger. Boost pressure drop at high rpm may notbe totally eliminated. The EVC IV will not be able to compensate for pressure loss due to turbocharger sizing. Boost creep or boost spikes due to inadequate wastegate flow capacity, lean air/fuel ratio, poor compressor design, or excessive backpressure may not be fully alleviated. Increasing the boost pressure will also increase the intake air temperature. If the intake air pressure exceeds 220 degrees Fahrenheit (100 deg. Celsius), performance increases may be minimal and detonation may occur. For best performance and to safeguard against detonation, always use the highest octane gasoline available (92-octane minimum). Do not rely on the factory boost meter (if equipped) when adjusting the maximum boost pressure. Install an HKS auxiliary boost pressure meter to monitor manifold boost pressure levels. The utilization of an HKS exhaust gas temperature (EGT) meter is recommended to monitor engine conditions (rich or lean air/fuel ratios). Mount the EVC IV control unit and harness away from high-power two-way radios, mobile phones, and their respective antenna cables to prevent malfunction of the EVC IV unit.
