Does anyone know which knock module this is the part number for 16188709 and if it will or will not effect performance when compared to the LT4 module. help

 

It is for a 94-95 caprice with a 4.3l v8. I would not use it if I were you. This engine is a lot lower compression wise so I am sure it wont detect the same spark knock as the LT4km.

 

Following that logic, an LT4 knock module is definetely not OK to use in an OBD1, correct?

Let's see:

Intended for LT4 engine
Intended for DUAL knock sensors
Intended for OBD2 computer

Yet somehow tons of people still use it in 94-95 OBD1 cars, ranging from a Camaro to a 4.3 Caprice.

Beleive it or not, switching from that knock module to a module for that year will not make much of a difference. You can put it on the dyno and compare them side to side if you wish.

 

Does it have any type of effect on tuning?

 

No.
