Is BlueTooth ELM327 good?
There are problems with Chinese BlueTooth ELM327 clones. It is true that the ELM is only as good as it’s user. Genuine ELM is well made and can communicate through all OBD II protocols and is only limited by its user’s wisdom to use all ELM options. Different case is with Chinese clones – there are nice labels on those devices “Supports all OBD II protocols”, but real life is different. Newer Chinese devices are different from what they used to be. They used to copy ELM chips, but now they made a new device with their own firmware for chips inside the device, added some major protocols and called it ELM327. Those devices do not support necessary commands for ELM configuration and some of them even does not support necessary protocols. Chinese devices are working with some diagnostic software like Scanmaster ELM or Torque PRO on many car models, but 2.7 CRD Jeep ECU and TCM data transfer is much more complex and newer clones are not supporting them. This is the reason why our diagnostic software does not work with many Chinese ELM327 devices. Older Chinese USB clones seem to be working well with our software, problem is with many newer devices. We cannot do anything about this. With problematic ELM327 device you will get answers: Fake ELM.
