Only *some* CIS-E is knock sensing.  For example, the 1985-87 4000 4-cyl
MG engine has CIS-E and is knock sensing; but the 5-cyl 4000q and
Coupe GTs of the same era with the KX and JT engines are also CIS-E, but
not knock sensing.

I don't think so.  The pin-outs of the two ECUs are not compatible.
