## Description

Engine Link turns your iPhone into a powerful OBD-II vehicle diagnostics tool. It connects to OBD-II ECUs via Wi‑Fi or BLE (LELink, Carista, Viecar, etc.), supports custom PID libraries, and lets you read and clear fault codes while monitoring real-time engine data with customizable gauges.

Features include DTC/ CEL reading and reset, data graphing, MPG real-time widget, HUD mode for night driving, multiple ECU support, preloaded GM/Ford PID libraries, and the ability to add your own libraries. It offers no subscriptions or in-app purchases and supports advanced PID formulas for enthusiasts and professionals alike.

## Review summary

Engine Link offers powerful custom-PID diagnostics and highly configurable dashboards, with good vehicle/app versatility and affordable pricing. However, users repeatedly face connectivity problems, inconsistent adapter compatibility, and regressions after updates that can disable gauges or codes. Code coverage is incomplete, missing several sensor-specific readings, and the UI feels dated. Overall, it’s valuable for advanced users who need multi-parameter dashboards when it connects, but reliability and consistency across devices and updates vary.

### Pros

- Supports custom PID files, allowing advanced diagnostics beyond standard OBD-II codes.
- Highly customizable dashboards with multiple gauges, enabling monitoring of many parameters at once (e.g., multiple dashboards with numerous dials).
- Broad hardware/vehicle compatibility and strong value for money.
- Long track record of reliability across many vehicles and iOS devices.
- Helpful developer/expert support to set up PIDs and troubleshoot.

### Cons

- Frequent connectivity issues and instability; often won't connect or reads nothing.
- Inconsistent compatibility with certain adapters (e.g., some MX+ or Wi‑Fi dongles not supported).
- Update-related regressions where gauges stop working or the app fails to connect after updates.
- Limited/missing codes; relies on generic OBD-II codes and misses several sensor-specific readings (e.g., P0327, ABS, yaw).
- Dated, unintuitive UI; clunky navigation and layout.
