what is the difference in resistance reading between the lt1 and lt4 knock module. cant you use your lt1km then just solder a resistor in the line?? ive seen it done with tpi engines when they swap from maf to sd and was just curios because im gonna be buying a lt4km soon.

thanks

This belongs on "LT1 Engine Tech".... but to answer your question..... the knock module is a chip with a fairly complex filter circuit on it, to filter out noise signatures/patterns/frequencies that are known NOT to represent engine knock. The chances of picking a resistor that would allow the LT1 module to assume the charcteristics of the LT4 circuit would appear to be unlikely.

What are you trying to accomplish? The knock module is a $25 item, that is prepackaged to fit into the socket in the PCM.

Are you getting a lot of KR now? I never noticed that the LT4 KM made any difference.

Do a board search and get the value of the resistor at Radio Shack and put it inline from your knock sender unit on the pass. side of the block,by the starter.

thats what i was refering to.thanks. i was just wondering if it was possible with these.anyone ever done it before?
