4agze timing

[jondee86]

Referring to this diagram from the document linked above, you can see
that the GZE igniter has a module for decoding the ECU signal that tells
the igniter which coil to fire. The 4AGZE uses only two transistors because
it has only four cylinders.



I have never heard of anyone using the GZE ECU and igniter to drive COP's.
This pic is said to be an early 2-wire Toyota COP from a "Tundra" in the
USA market. There are probably others, but I have no idea if any of them
are going to fit on your engine.



Since there is little or no performance advantage from using COP's, it may
be better to just continue with 2-pole wasted spark coil packs ?
