Hey everyone- was just messin around while installing my nitrous kit yesterday and since i had to pull the ECU out to run some wires i decided i'd look in the "knock module" port on the ECU.. the module that is in it doesnt look very old- of course it is like air tight in there once you screw those screws down on that seal..

what i'm needing to know is how to tell if the people i bought the car from put an LT4 knock module in it or not since they say they dont know..

The car has 1.6 aluminum roller rockers- but they had the computer reprogrammed by a friend of thiers down there who does corvette and f-body computer programming..

Thanks
