GM knock sensor thread Options

[lagos]

is that an ATS TB inlet? looks nice. i ordered one last week!

Yup, I ordered that and the GM Knock Sensor Conversion for Doc to install. Along with the healthy dose of goodies that he's putting in the car.......should be really niiiiiiice.

i woudlnt recomend using the GM knock sensor. it dosnt work correctly for our cars and ats should stop selling it imho. keep the stock sensor.

Whether the sensor resonates at 5.7k or 6.3k or whatever shouldn't matter much as long as the filter is setup correctly.

belive it or not, i have done audio engineering for a living . i dont think there is a narrow band filter inside the ecu that is filtering on a software level. i think its all done on a hardware level by using a narrow band microphone (knock sensor). as you know, anything thats narrow band, means that it is tuned to that one frequency and setup to cancel everything else out. if it was all done in the ecu, then you would just use a 20-20hkz wide band sensor.

but, even if there is some type of software filtering going on, youll alwasy get better performance out of a microphine (kock sensor) that peaks at 5.7k then one that peaks at 6.3k on a spectrum analizer (if 5.7k is the frequency your trying to listen for) .


edit: we can do this all day long.... having said that, this ended up turning into a cool tech thread
