• The ELM327 is a further development of the legendary OBD2 Interpreterchip family ELM320, ELM322 and ELM323. These ELM chips are used as the basis for diagnostic interfaces between a compatible OBD2 / EOBD vehicle and a commercially available PC / laptop.
  • The ELM327 combines all previous ELM chips in a single chip for the first time and also supports the CAN protocols (ISO 15765-4 with 500 kbps and 250 kbps with 11 bit and 29 bit IDs).
  • The ELM327 thus contains the accumulated experiences of tens of thousands of ELM320, ELM322 and ELM323 chips that have been used up to now. This further development underlines the leading role of the manufacturer. To date, no replicas of the ELM320 / 322/323 chips have achieved their performance.
  • For ELM chips, the world’s largest range of OBD software is available.

A modified version is available for use in the Ford area! This supports the HS-CAN and the MS-CAN. This modification, which is also incorporated into the programs, ensures that all control units can be read in our Ford models.


The operator has a small toggle switch, which can be switched to HS-CAN and vice versa if MS-CAN is required.
The following graphic shows perfectly which control units are running in which CAN bus:
