Ok guys,
So a late model euro cvs turning dizzy only has vac retard? So on boost it is 29 deg btdc right? So my US 87 930 is 26 deg btdc also. It has a dual pot one for vac retard the other side for vac advance. The dizzy will not respond to boost pressure because the signal on both sided of the pot on boost cancel each other. If euro= 29btdc then US 26btdc makes sense to me. Early 930s run less advance on boost, but they also do not have an intercooler. Wish I could get my hands on the factory bulletins covering the late "87" dizzys.
