Actually not tabetha. The Focus was the first (with others following quickly after) that use the data highway signal (digital) for all the engine dials. EOBD/SCP in the case of the Mk1/1.5 Focus. There is a legacy pulse signal for speed (radio & cruise control), but even that is conditioned through the PCM.

That's why anyone doing a standalone ECU (MS, Omex, etc) HAS to retain the PCM to drive the standard instrument cluster.

Walters00007 did you mean the ST170 pod (Mk1.5) or the ST225 pod (Mk2).
