Version 2.2 — a whole new look with Themes, deeper diagnostics, smarter tire-pressure warnings, faster time to dashboard, and new climate signals A new look - The entire app is redesigned with translucent Liquid Glass panels over a soft aurora backdrop — Dashboard, History, Inspect, Settings, and every diagnostic tool - NEW: Themes picker — choose a palette that recolors the whole app, each with its own Light and Dark variants, or turn the aurora off entirely Inspect & diagnostics - NEW: Enhanced DTC Scan sweeps the entire diagnostic bus, names every module that responds, and reads each one's fault codes — reaching body, chassis, and airbag modules a standard OBD-II scan never sees - NEW: ICCU Information tool reads your charging controller's part numbers, software version, build date, and serial number - NEW: Connection Report — an in-depth view of the app-to-vehicle link: adapter details, polling stats, per-module coverage, and an events timeline - Export results to CSV from DTC scans, the Connection Report, and any History session Tires - Warning colors now derive from your vehicle's door-placard pressures, with separate front and rear targets — fully customizable in the new Settings → Tires - NEW: Temperature compensation, so hot tires after a drive no longer trip a false warning - Pressures update 4x more often, and a sleeping sensor shows its last-known reading instead of a blank value Climate - The four vent and floor outlet temperatures now appear on the Dashboard, in CarPlay, and in History charts - NEW: Driver Position setting mirrors vent layouts for right-hand-drive vehicles CarPlay - Climate and Tires chips are now tappable — color-coded vent temperatures, and pressure/temperature pages that remember your choice - NEW: SoC Range Colors — set your own red/orange/green thresholds for the state-of-charge gauge, in CarPlay and on the Dashboard - The solid-red Brake Light style is back, and the Precondition chip is renamed "Battery Warmer" Faster and steadier - Time to dashboard cut by almost half — your first values appear within about a second of polling start - "Vehicle On" detection reworked: sessions end promptly after shutoff, and adapter hiccups no longer end a session mid-drive - Faster polling on OBDLink adapters, and smoother multi-frame handling on vehicles with very fast ECUs Charging - NEW: AC Draw panel and chart show wall-side voltage, current, and power while AC charging — the gap to pack power is your charger's conversion loss - Fixed a phantom "DC Fast" session at AC plug-in; the 12V battery now shows charge/discharge direction by color Vehicle coverage & languages - Korea-built IONIQ 9 now identified correctly; Standard Range packs no longer show two phantom 0° modules; cell-voltage grids show every cell on the Kia EV9 - Dozens of translation fixes across all nine languages, including proper battery terminology in seven of them
