Have you checked the prices for the controller and the ISV (Idle Stab Valve)?

In my experience with my '84 the timing control worked perfectly
well, though I presume it wasted a little gas.  And the newer system
is a good deal more complicated.

But to put one in, you have to connect ten wires to the controller
circuit from various places including the power steering pressure
switch.  You need to take air from after the AFM and before the
throttle (easiest way probably to use a 2.1l rubber intake elbow) to
go to the ISV and connect it into the intake manifold so the output
air can go there.  Bypass idle stab from the 1.9 system by plugging
the two plugs together and you've finished.  The ISV is
rubber-mounted on top of the manifold, and the controller and its
socket and wiring are forward of the right taillight assembly,
reachable by removing it.  No law I know says either one has to be
right there, though I note that the controller unit is mounted in a
fairly cool place

This is the condensed version, obviously.

Yours,
David
