The HKS-VA028-V2.0 is a dual-display digital panel meter designed for real-time monitoring of DC voltage and current. It is widely used in DIY electronics, solar power systems, and automotive diagnostics due to its compact size and integrated shunt (for the 10A model). 🛠️ Key Technical Specifications Voltage Range: 0 to 100V DC.
Current Range: 0 to 10A DC (typically includes a built-in shunt).
Operating Voltage: 4V to 30V DC (required to power the meter itself).
Display: 0.28" dual LED; typically red for voltage and blue/green for current. Accuracy: Approximately ±1%. Refresh Rate: ~300ms to 500ms. 🔌 Wiring and Pinout
The device usually features a 5-wire configuration divided into two harnesses: hks-va028-v2.0
The HKS-VA028-V2.0 is an aftermarket external wastegate actuator (often referred to as a "wastegate" or "gate") manufactured by HKS, one of Japan’s most venerable tuning houses. Its primary function is to regulate the boost pressure produced by a turbocharger. Unlike factory internal wastegates, which are often welded to the turbine housing, HKS’s external design allows for more precise, creep-free boost control.
The “VA028” designation refers to a specific model within HKS’s Standard Wastegate Series. The “V2.0” indicates this is the second generation, featuring critical design improvements over the original VA028.

Operating Instructions
Maintenance and Troubleshooting
Owners of the original HKS VA028 often reported two minor but irritating flaws: boost creep at high RPM and diaphragm fatigue after years of track abuse. HKS R&D listened.
The VA028-V2.0 introduces three revolutionary changes: Introduction Welcome to the user guide for the
Reinforced Silicone Diaphragm: The V2.0 employs a multi-ply, heat-shielded diaphragm that resists cracking from EGTs (Exhaust Gas Temperatures) exceeding 950°C. This directly addresses the failure points found in first-gen units and generic copies.
Optimized Valve Guide Geometry: The stem guide bushing now uses a self-lubricating bronze alloy, reducing lateral valve binding—a common cause of inconsistent boost oscillation.
New Spring Retainer Design: The V2.0 ships with a revised upper spring seat that allows for easier preload adjustment without specialized tools. Tuners report that incremental boost changes are now far more predictable.
The VA028 creates a map using nodes. You define points (e.g., 1000 RPM, 3000 RPM, 6000 RPM).
