*SPECIAL ORDER
Application
- CIVIC TYPE R FK8 (2017, 2018, 2019, 2020)
■Product Series Features
- Plug-and-play installation connects directly to the FK8's sensor harness using a dedicated coupler - no wiring changes needed.
- Unlike a basic boost controller, Power Editor R uses vehicle speed, throttle position and RPM for gear-specific boost mapping that adapts to your driving.
- Preloaded with optimized boost maps for instant performance gains right after installation.
- Free Easy Writer software enables custom tuning to match your exact mods and driving conditions.
■Vehicle Specific Kit Features
- Introducing the "Power Editor R" - a new boost upgrade kit for the FK8 Civic Type R .
- It utilizes more sensor inputs than the standard Power Editor for seamless power delivery across the entire RPM range.
- The kit includes two preset maps:
- Map A: For stock airbox
- Map B: For cold air intake
Note: Must remove HKS AFR (if installed). HKS AFR is a product that comes with the cold air intake (not the stock AFR sensor).
- Easily switch between maps using the included harness.
Note: Switch sold separately. - The system can be easily returned to stock settings - simply use the included return connector to restore stock operation.
Note: Vehicle will not start with HKS Cold air intake setup without proper fuel tuning. - Installation involves intercepting four sensor channels:
・ Ch1: Boost pressure ・ Ch2: Intake manifold pressure
・ Ch3: Air flow ・ Ch4: Throttle position
・ Cam angle sensor (RPM signal)
・ Vehicle speed input (optional)
