OK, euro boost retard is as I concluded and as Brian stated from his test of putting vac and pressure to a euro dist.
Looking at the first graph bellow, the euro retard is not "boost retard".
It is "vacuum-retard". To the tune of about 11 deg's.
Again, at cruse Vaccum-Advance is in control of timing. With acceleration and loss of vacuum, advance is reduced and in effect retarding timing for on boost operation.
Mistry solved. Cool
