If I got a PCM for my car do I still need the knock sensor?

 

your question is vague.
do you mean if you got your computer reprogrammed, would you need a LT-4 knock modual. You can have your knock sensor de-sensatized in your computer if you have someone reprogram it. But I would not recommend dleting it.

Sorry....I know everyone is recommends the LT4 Knock Module. Someone mentioned that because I had the OBD1 conversion from PCM forless I would not need it. Is that correct?

Are you talking about sensor or module?

You always need a sensor and there is not an "LT4" knock sensor. Converting to OBD-I has no bearing on what module you might want.

 

So shoe....I still need the LT4 knock module?????

 

An LT4 Knock Sensor is the same thing as a 96-97 LT1 Knock Sensor. You're talking about the knock module which is located in the PCM.
As for whether you need it or not, it's not a necessity regardless if you had a 94-95 or a 96-97 car. Some people have seen some less knock retard with them, but if you're not getting any knock retard at all, you don't need one.

 

So I should just wait and see then? Will it throw a code is I do get some knock?

 

To add to the confusion...

When you switch from OBD-II to OBD-I, you need to replace the high impedance (96/97) knock sensor with a low impedance (93-95) knock sensor.

 

You gotta be kiddin me Injun.......geeze why doesnt it say that on the PCMforless site? What next? Always something.
