Mode 6 is ignored by the EC2 in the versions compatible = with=20 the EM2.  They have the manifold pressure ignition control that = advances=20 timing at low MAP and retards it during boost.  

So Todd,=20 can you confirm that you were using the chips that came with your EM-2 = when you=20 detonated your engine?  If so, the timing retard alone would appear = to not=20 be enough to stop the damage.
