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.

the stock (toyota sensor) might tend to blow at times...so you want to put a different frequency sensor in so it blows less ? correct ?

No, thats not what ( some / few / many ) people are saying. When excessive knock happens, how long will the sensor last? All motors get knock, even when everything is running perfectly. Only in this case, the knock is like 4 counts / second (microphones pick up background sounds). When you get 50+ knocks / sec - something is wrong.

The stock sensor is known to be more fragile then most and fail after a few cases of excessive knock. The real question here is whether the GM knock sensor is listening for the correct frquency. Knock sensors listen for specific frequencies to determine knock - otherwise valve or injector tick would through off the system. Does the GM sensor listen for the same frequencies as the stock sensor?

From my experience, I believe so.
