Before writing a tuned file into the ECU, it is very important to proceed to a second read. In some cases, the manufacturer may have done an update on the ECU without the customer being aware of it.

The risks in a case like this are important:

  • The car won't be able to communicate via OBD.
  • Writing an obsolete file will cause the car to be useless (impossible to start)
  • ECU recovery will request the manufacturer's help.
  • The car warranty will therefore be nulled.
