Which one
Start with your phone and your car.
The right adapter depends on two things: what you will use it with, and whether you need every module or just the engine.
02 — iPhone
If you have an iPhone or iPad
iOS does not support classic Bluetooth: a normal ELM327 Bluetooth will not work. Look for Wi-Fi or Bluetooth LE (4.0).

Common questions
What people ask us most.
Does a Bluetooth ELM327 work with an iPhone?
No. iOS does not support classic Bluetooth for these devices. On iPhone you need a Wi-Fi or Bluetooth LE adapter and an app that supports it, such as Car Scanner.
Is there a genuine ELM327 v1.5?
No. The original maker only released versions 1.0 to 1.4b and 2.0 to 2.3. "v1.5" is a clone number: the version is just what the firmware reports. What matters is the chip; the PIC18F25K80, found in the best-rated clones, is in every generic ELM327 sold by Satkit, whether it reports v1.5 or v2.1.
What do I need to use FORScan on a Ford or Mazda?
An adapter with access to the MS-CAN network: a modified ELM327 with an HS/MS-CAN switch, or one that switches by itself such as the ELS27. To program modules, USB is best.
Does it work with any car?
For reading engine faults, almost any car with an OBD2 port: in Europe, petrol cars from about 2001 and diesels from about 2004. Other modules depend on the brand, the app and the adapter.
