Hi Al,
I fail to see how installing another CAS will 'dramatically' reduce=20
risk of all ECM causes.

  We have already said we have no history of failure of the CAS, how can=20=

installing another CAS (with no history of failure), 'dramatically'=20
reduce the risk of failure?

And how can installing another CAS have any influence on "the risk of=20
all ECM causes" ?

I also have great respect for redundant systems, but I cannot see your=20=

logic in this one. It is the 'dramatic reduction' that troubles me.  =20

It's not just crank angle sensor that is the risk item. Going to
redundancy with the CAS will dramatically reduce risk of all ECM
causes. Like this connector risk. I'm not always proponent of
redundancy, but with my limited info on this item, I=A0SUSPECT it's
significant, positive step.</x-tad-bigger></fontfamily>
