ELM327 OBD2 Adapter: The Clone Wars

Most “Dr. Prius won’t connect” issues come down to low-quality ELM327 clones. Hybrid-specific apps often require features (like switching ECU headers) that generic apps don’t. Browse the tested adapters below — and use search to quickly find a model.

Dr. Prius OBD2 clone adapter comparison
PS: Most adapters are Android-only. iOS users typically need BLE-compatible adapters. (See notes inside each card.)
Tools/apps used for testing
  • ELM327 Identifier
  • Elm327 OBD Terminal
  • Dr. Prius App
  • Hybrid Assistant App
  • Torque App
Quick guidance
  • If it “works in Torque” it still may fail in Dr. Prius.
  • Avoid mystery “Mini ELM327” listings with inconsistent internals.
  • Prefer known BLE adapters for iOS.
