HDi Multi Function Boost Controller (MFBC)
Direct Control. Predictable Boost. Total Confidence.
The HDi MFBC uses a true Open-Loop boost / HDi-Intelligent Closed Loop Control system (ICLC), giving you direct command of the wastegate solenoid. Unlike generic closed-loop controllers that is hard to set up / constantly chase target boost and cause spikes or oscillation, the MFBC delivers smooth, repeatable boost every pull.
Open-Loop Boost Control /(ICLC), (Why It’s Better)
You control the solenoid duty cycle (DU value) directly
Boost response is linear and predictable
No ECU learning, no boost hunting, no sudden overshoot
Ideal for high-load, racing, and off-road applications
Once set, boost stays exactly where you tuned it—even under hard acceleration and sustained load.
Real-Time Boost Monitoring
A built-in 65 psi pressure sensor continuously reads intake manifold pressure and displays it live on the screen. This allows accurate tuning and instant feedback without external gauges.
High-Pressure Solenoid Control
The MFBC drives a 120 psi HDi high-speed solenoid, providing fast and precise wastegate control. This ensures:
Faster spool
Stable peak boost
Reduced boost creep
Dual Boost Modes
Switch instantly between Low (L) and High (H) boost modes with a single button:
Low boost for traction, daily driving, or endurance runs
High boost for track, dyno, or competition use
Each mode stores its own settings—no re-tuning needed.
Simple, Safe Adjustment
Boost is set by:
Applying full throttle in 3rd gear
Adjusting duty cycle (DU)
Testing and fine-tuning
No laptops. No software. No hidden tables.
Just mechanical logic backed by electronics.
Clear Digital Display
The screen shows:
Boost pressure (PSI or Bar)
Engine RPM
System status
Everything you need. Nothing you don’t.
