CarScan vs OpenBimmer

CarScan reads your car's fault codes through an OBD-II adapter and explains them in plain words — no dictionary of abbreviations, no "see your dealer". WHAT IT DOES • Polls the control modules and shows which answered and which stayed silent. • Reads fault codes and decodes them: not just «P0171», but what usually stands behind it and what is cheaper to check first. • Shows live data: RPM, speed, temperature, pressure, engine load. Remembers the lowest and highest value of the trip. • Records a trip to a file — for the intermittent fault that never shows up at the garage. • Shows inspection readiness and on-board monitoring test results. • Resets the service interval — where the car allows it. • Builds a report for the mechanic in plain text: forward it or print it. • Demo mode: walk through every screen on a made-up car before buying an adapter. HONEST ABOUT THE LIMITS An OBD-II adapter is required and bought separately. Any of four kinds will do: Bluetooth, Bluetooth BLE, Wi-Fi or USB. A service reset is not possible on every car and not with every adapter: it needs talking to modules directly, and cheap ELM327 clones cannot do it. The app checks whether your adapter can, and says so plainly instead of trying blindly. If a module stayed silent, we write exactly that — «did not answer». It is not the same as «no faults». WHAT STAYS WITH YOU Trip recordings, communication logs and parameter snapshots are kept on the phone only and never leave it by themselves. ACCESS The app is free for the first few days, so you can see that it talks to your particular car. After that a licence is required. LANGUAGES Russian and English, switchable inside the app. SUPPORT Write to us from inside the app, on the Support tab — the answer arrives there. Privacy policy: https://carscan.app/privacy/

OpenBimmer turns a Bluetooth LE OBD adapter into a live dashboard, data logger and diagnostics tool. It is built for BMW turbo engines (N54, N55, B58, S55, N13, S58, S63) and works with any car that has an OBD-II port. LIVE GAUGES - Boost against target, ignition timing, intake, coolant and oil temperature, lambda and AFR, fuel rail pressure, load and more - Peak hold, min and max for every value and a shift light that follows your engine's redline - Choose what every gauge shows DATA LOGS - Record pulls with up to 34 channels - Scrub through them on a multi-channel chart - Export CSV for datazap or a spreadsheet DIAGNOSE - Read stored, pending and permanent engine fault codes with descriptions - Clear codes, check readiness monitors, read the VIN and battery voltage PERFORMANCE TIMER - 0-100 km/h, 100-200 km/h, 0-60 mph, 60-130 mph, 1/8 and 1/4 mile - GPS or OBD speed, history and best times FREE, OPEN SOURCE, PRIVATE - No account, no ads, no tracking. Your data stays on your phone. - Source code: github.com/openbimmer/openbimmer (MIT license) WHAT YOU NEED An ELM327-compatible Bluetooth LE adapter, for example Vgate iCar Pro BLE, Veepeak OBDCheck BLE, vLinker BLE or OBDLink CX. No adapter yet? The built-in demo adapter lets you try everything. OpenBimmer reads standardised OBD-II data and never writes software to your car. Never use the app while driving.
