The HKS VA028 V2.0 is not just a resistor trick; it is a sophisticated, standalone piggyback fuel controller designed in the golden era of tuning. While modern ECU flashes have largely replaced it, this unit remains a favorite for older platforms (like the MR2, Supra, and RX-7) where OBDII flashing isn't an option or where a standalone ECU is overkill.
4V to 30V DC (required to power the meter itself).
The is a specific model of a Mini Digital Voltmeter Ammeter commonly used for precision electrical monitoring in automotive, solar, and DIY electronic projects. It is a "Panel Amp" meter that provides real-time dual displays for voltage and current. 1. Technical Specifications While specific datasheets can vary by manufacturer, the HKS-VA028-v2.0 hks-va028-v2.0
Connect the thin red and black wires directly to your isolated 12V supply.
Key implication: expect interaction with vehicle systems, engine sensors, actuators, or firmware flashing tools—so electrical, mechanical, and software compatibility matters. The HKS VA028 V2
The meter comes with a standard wiring harness (usually 5 wires) that makes installation straightforward. The terminal colors are designed to match standard automotive or electrical wiring practices, allowing for a "plug-and-play" experience for experienced technicians. 4. Wide Application Range
The HKS-VA028-V2.0 is a 0.28-inch LED digital panel meter that combines a DC voltmeter and an ammeter into one unit. It is often referred to in the market simply as a "10A/100V Dual Digital Meter." The "V2.0" designation usually implies an updated design for better stability or screen brightness. The is a specific model of a Mini
Dual 0.28-inch LED displays, usually color-coded (Red for voltage, Blue for current). Refresh Rate: Approximately 300ms to 500ms per update. Accuracy: Generally rated at 1% (±1 digit) . Performance Highlights
