Why should you care about the jump from v1.0 to v2.0? Here are the three main highlights: Optimized Thermal Management

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. or specific pinout instructions for this version

Note: If this identifier appears on a software file (e.g., .bin, .hex, or .pdf), treat it as a proprietary revision; do not attempt to flash or install it without explicit matching hardware and HKS guidance.

When measuring a target source that drops below 4.5V or exceeds 30V, you must use an independent 9V or 12V power supply to run the meter safely.

This compact digital meter is packed with features that make it a versatile tool for monitoring electrical systems:

Verify that the thick red and black lines are wired in series with the return path. If they are wired in parallel across a power source, they will blow the internal shunt instantly.

The V2.0 revision often features a 5-wire setup, split into two main connectors for power and measurement. 1. Power Supply Connector (3-wire, thin)
