I am looking at installing a digital wur on a 1988 930 track car. It currently is running without an 02 sensor and the timing valve is running at the default value, On Andial fuel enrichment system is handling fuel enrichment at higher bust levels. My question is can the timing valve and related wiring me removed when running a digital wur, or will the fuel head need to be backdated.
