Opus ignition

[ADIPaul]

Hi,
Just wondering if anyone can tell me which Lotus models (if any) are fitted with the Lucas OPUS ignition and is it the AB3 module?
If you're not sure which that is, go to my web site and look around for ReOpus links.

Basically all Lotus 9XX 4-cylinders from 1983 through the introduction of the GM GMP4 Engine Management system. Timing of that intro varied in different markets, but it was 1989 in the USA.

The Lucas amp has a GM amp inside of it. Just crack the Lucas case open and there it is complete with GM part numbers.

The distributor mounted trigger module is getting hard to find. If you find a good working one, keep it.

When they fail, many folk are switching to Pertronix since it fits inside the distributor in much the same way and looks the part.

Tim
