So I have two questions about this "LT4 Knock Module"

1. Dealers have never heard of it and the part numbers ive seen dont exist on performance websites. Where can i buy this thing?

2. I also heard through the grapevine that it wont work on a 1993. Is this true? The PCM looks the same as the ones in the photos of installation of it but who knows until i buy it and try putting it in.

 

P/N: 16214681, any dealership. Thay might have to order it if it's not in stock. Got mines from Sam Taylor $32 shipped. 93s don't have provision for a KM on the PCM.

 

1)Dealers are idiots :P

2)no wil not work on a '93

 

well **** me. i want a new PCM then cause i still think im lacking performance from my computer. maybe that check engine light is for something else?

 

A scan of it will tell you why your SES light is coming on. Try getting a performance chip for it.

 

One benefit of the computer in the 1993, is that you can retrieve the trouble codes yourself without a scanner.
