Question LT4KM on a 93?

i was reading the 93 specific information and it said something about the 93's not being able to use the LT4KM. Why is this?
TIA

Believe the 93 still used a ECM. They switched to PCM in 94. I may be wrong.

The 1993 does not use a replaceable knock module.

Before you desensitize the 93 Knock module with the resistors try logging some runs. The 93's knock module are not as sensitive as the 94+ ones. So, before you jump on the knock sensor bandwagon get some datalogs!
