    It will only affect it if the ecu you use checks for a knock sensor, because if it does then the ecu will throw a code for it and won't activate VTEC

    therefore making an ls-v swap useless...either hook in a knock sensor or a chipped ecu eliminates the knock sensor

    Vtec will still activate. However, your timing will be retarded by the ecu and redline will be lower by about 500 rpm's or so... Try running the wire for the knock sensor to a good ground. Sometimes this method makes the ecu think the knock sensor is there and is in working order but, sometimes it'll just get rid of the check engine light and still retard the timing. It all just depends on how your ecu is feeling at the time lol.
