I just got my lt4 knock module in the mail from Jason Cromer. Ordered it more than a month ago..................but anyway. Should the lt4 knock module look exactly like the stock knock module that came in my 94 Z28? I bought this car used and the headers were already on it so I don't know if the previous owner already put one in. ------------> Brad

 

Yep, they look pretty much the same. It should have the part number on it though. You can just compare the part numbers. They should be different.

 

Alright cool, your right the numbers are different. Has anyone actually noticed a difference from adding one of these? Do I need to reset the computer or something? ----------------> Brad

 

The LT4 km was my first mod actually and i noticed the car seemed to pull better at low speeds in higher gears. I would usually take corners in second and the car could pull right off the corner much better. I never had my scanmaster when i had the stock KM so i don't know how much knock i was getting.
