Are you saying the injector impedence changed in 93 or that is what must have happened IF the modules had been eliminated?

It's been low on the list, but I will have to email them at some point.

If the modules changed and aren't interchangeable, I'd guess it's because the injector impedance changed.

Interesting. Could be. I know with the megasquirt the power key becomes basically a programmable input. Maybe it's just based on wiring differences in the switch circuitry.
