CarCoding

Connect your ELM327 adapter and unlock live diagnostics, AI fault analysis, and ECU coding — all in one app.

CarCoding turns your iPhone into a professional car diagnostic tool. Connect any Bluetooth ELM327 OBD2 adapter and access real-time vehicle data, fault code analysis, and ECU coding all in one app.

LIVE DASHBOARD Monitor your engine in real time with animated circular gauges: RPM, Vehicle Speed, Coolant Temperature, Boost Pressure, Throttle Position, Fuel Level, Battery Voltage, Intake Temperature, and Engine Load.

FAULT CODE DIAGNOSTICS Scan and clear DTC (Diagnostic Trouble Code) fault codes directly from your vehicle's ECU. Each code comes with a plain-English explanation, severity level (Critical / Warning / Info), and possible causes so you know exactly what is wrong before visiting a mechanic.

AI MECHANIC (Pro) Chat with our built-in AI-powered Mechanic. Ask about any fault code, get repair cost estimates, urgency ratings, and step-by-step DIY fix instructions. The AI already knows your vehicle model and detected fault codes, no copy-pasting required.

ECU CODING (Pro) Unlock hidden features in your vehicle's ECU. Fold mirrors on lock, enable needle sweep animations, disable speed limiters, and more. Includes dedicated coding profiles for more than 15 popular vehicle brands.

VEHICLE AUTO-DETECTION CarCoding automatically reads your VIN via OBD2 Mode 09 and identifies your vehicle including make, model, year, and engine code. Manual selection is also available for all supported brands.

ADAPTER COMPATIBILITY Works with most Bluetooth Low Energy OBD2 adapters that support the standard ELM327 command set.
