HKS EVC 7 MR Boost Controller

Key Improvements of EVC7-MR

• HKS’s high-end boost controller EVC7 has been upgraded with a newly redesigned stepping motor at its core and is now released as EVC7-MR.
• By redesigning the internal body structure and shaft based on the latest technology, the system delivers more precise and stable boost control.
• The pressure adjustment step has been reduced to half that of the previous model, enabling more advanced pressure control that improves both boost response and stability.
• Compared to the conventional stepping motor, torque has been increased by approximately 5 times. This significant improvement enhances control response under high-boost conditions and allows for more stable boost control. Testing has also shown improved boost pressure stability after interception, making tuning easier and more consistent.
• In addition, the PC-based boost setting software “Easy Writer” remains compatible, allowing for more detailed and precise tuning.

* When using polarized sunglasses, screen visibility may be reduced depending on factors such as the type of lenses, their compatibility, and the viewing angle.

Features

• The display features a 2.4-inch full-color TFT LCD. Its clean display layout, optimized character size, and font ensure excellent visibility even while driving.
• Boost settings are adjusted using a simple rotary dial, allowing for easy operation even when wearing gloves. With four independent boost settings, users can switch configurations according to different driving conditions.(The correction map grid consists of 10 × 10 points.)
• The controller is equipped with the “EVC HIPER-ENGINE II” CPU, carried over from the EVC7.It offers high control processing speed and supports CAN communication.
• Key functions required by high-end users are fully retained, including support for high boost up to 300 kPa, four boost modes, compatibility with throttle position, engine speed, and vehicle speed signal inputs, and a map correction function. This makes the unit an ideal boost controller for heavily tuned vehicles.
