Contact the HV Electronics NZ Telemetry & Specification Archive
Submit sensor calibration errata, CAN-Bus DBC frame updates, or Open-Meteo circuit telemetry feedback to the HV Electronics NZ engineering desk, or connect directly with DTech Motorsport in Tauranga for active retail stock of physical HV Sensors hardware in New Zealand.
1. Physical Hardware Supply & Replacement Sensors in New Zealand
The hvelectronics.co.nz engineering portal is a non-commercial specification archive and calculation workbench; we do not process online shopping carts, hold physical inventory, or dispatch courier parcels. If you require a replacement HV 4-Bar MAP Sensor, HV Fast-Response Air/Coolant NTC Thermistor, HVLC2 Dual Lambda CAN Module, or HV EGT Type-K CAN Amplifier for a New Zealand competition vehicle, active retail stock is supplied by DTech Motorsport (Tauranga, NZ) ↗.
2. Calibration Errata, ECU Preset Contributions & Open JSON APIs
We maintain two public, zero-authentication JSON endpoints under a Creative Commons Attribution 4.0 (CC-BY-4.0) license for motorsport data engineers, telemetry dashboards, and pit-wall tooling:
/api/v1/hv-sensor-calibrations.json— Complete machine-readable transfer functions, voltage-to-pressure tables, NTC resistance curves, connector pinouts, and archived 2018–2022 NZD reference pricing./api/v1/nz-track-air-density.json— Live 30-minute barometric pressure, ambient temperature, relative humidity, Relative Air Density (RAD %), and Density Altitude across all six active MSNZ/FIA circuits in New Zealand.
3. Pre-Flight Troubleshooting Before Submitting a Sensor Issue
Before suspecting a faulty pressure transducer or CAN module on the dyno, verify three physical layer parameters: (1) confirm the ECU 1K/2.2K internal pull-up resistor is switched OFF on 3-wire 0–5V ratiometric MAP/pressure channels and ON for 2-wire NTC thermistors; (2) check that the MAP sensor reads approximately 1.34 V at sea-level atmospheric key-on (100–101.3 kPa absolute); and (3) measure 60 Ω between CAN-High and CAN-Low with power off on 1.0 Mbps trunks.
Archive Reference Scope, Open Datasets & NZ Motorsport Provenance
The HV Electronics NZ technical portal (hvelectronics.co.nz) preserves the engineering datasheets, linear 0–5V transfer functions, Steinhart-Hart NTC thermistor curves, 1.0 Mbps CAN-Bus Big-Endian payload layouts, and historical 2018–2022 NZD reference pricing from the original New Zealand motorsport electronics catalog. All interactive calculators—including the 4-Mode Motorsport EFI Workbench, the 6-Circuit New Zealand Track Air Density (RAD %) board, and the Web Crypto SHA-256 telemetry integrity verifier—are provided free of charge for race engineers, ECU tuners, and motorsport wiring harness builders across Auckland, Waikato, Manawatū, Canterbury, Otago, and Southland.
