SEQUENT FAST is a new calibration/configuration method for SEQUENT systems that is faster and easier to use. It enables the installer to make a new configuration with the stationary vehicle1, in a few minutes. The installation is simpler too, being generally unnecessary to connect the rpm, TPS and lambda oxygen sensor signal. The components used by SEQUENT FAST are the same already used for the standard SEQUENT. The SEQUENT FAST programme on PC is new, easier to use and completely separate from the standard SEQUENT, even as regards the database. The guided personalised process is shorter and easier.
