Tach signal / knock sensor power increase?

[flaatr@yahoo.com (Euroroc II)]

Interesting technology... the ICM is a thick film alumina substrate all 
chip and wire construction. Non-hermetic package but filled with a type of 
silicone... very tacky but does not flow but protects the die from the 
environment but flexible enough not to put stress on the bond wires.

Interesting.
