hello
problem with elm 327 interface
not communicate with Bosch and Marelli engine control
communicates with all others but without engine??
after 3.2 update

Which ECU model?

Do you mean that it worked in older versions and it doesn't work now?

yes .. it worked in the old version
Perhaps a coincidence...... but now does not work with any engine control unit
but it's fine on all other control units .. instrumentation, service,abs,airbag...........ECU but not
