Which ECU model?

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

[mario nazzareno]

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
