Hks-va028-v2.0

The HKS-VA028-V2.0 is a compact, dual-display digital panel meter designed to monitor DC voltage and current simultaneously. It is widely used in DIY electronics, battery monitoring for vehicles, and solar power systems due to its low cost and high utility. Core Specifications

Build Quality: Reviewers on Amazon have mentioned that the meters are "accurate, durable, and easy to install". However, one user warned against bending the wires too sharply, as PCB flex can cause errors in current measurement. hks-va028-v2.0

  • Symptom: communication errors (no CAN/OBD connection)
  • Use datalogging during initial runs to confirm safe operation across load/speed ranges.
  • Tune incrementally: one parameter at a time, validate, then proceed.
  • If using a third-party tuner, provide full logs and details about V2.0 changes.
  • Revert to stock/backup if abnormal behavior occurs (surging, misfires, limp mode).

    • Step 2 – Spring Selection The V2.0 ships with a 0.8 bar spring. For low-boost applications (<1.0 bar), install no shims. For 1.2–1.5 bar, add the included 0.3mm shim. For racing (>1.8 bar), purchase the HKS VA028-SPRING-HD kit. The HKS-VA028-V2

    Most V2.0 models have small potentiometers on the back to fine-tune voltage and current readings if they seem slightly off. 4. Common Troubleshooting No Display: Symptom: communication errors (no CAN/OBD connection)

    Common Ground: Ensure that the negative of the power supply and the negative of the measurement system share a common ground if they are separate sources.
