The other thing is, just because you can't hear it pinging doesn't mean that
it isn't.

It would depend on the internal condition of your engine. Being a '92, I
would
imagine that the compression has risen a little over these years so using
89 would be questionable.
I use 92 octane with the '96 MP PCM and have never tried 89 in it. My
engine
is low mileage for a '97. I did have had one pinging experience (going up
small
inclines) with mine but narrowed the cause to a 'suspect' no brand tank of
gas.
Putting in a bottle of octane booster got rid of the pinging.
