I have collected 14 different sensors for testing and have only found
the DR number or in the case of a Quad 4 10456209 number.

The last 4 digits are the date code.  Usually the year and day of
manufacture (Julian Calendar).  I have profiled the sensors by getting a
1/4 NPT pipe coupling and screwing one sensor in one end and another
sensor in the other end. I set up with 2  DR562      sensors. I applied
a sine wave from a HP 3324A to one sensor and looked at the output of
the other sensor with a Nicolet 440 scope. with 1 VPP amplitude I sweep
the frequencies from  1Khz to 50 Khz The highest amplitude was always at
6 Khz. Of the 14=20

sensors I tested they all responded the same. I concluded that the
sensors are not all that different and could be interchanged.I then
tested 9 external det modules from AASS,HKD,HKR,BLN,ANBZ ect.  The
output is 10 volt until between 4 Khz and 12 Khz the output would go low
. Again 6 Khz was the sweet spot.    =20

	Hi All,

	=20

	I went to the junk yard to gather parts and pulled several knock
sensors off of Chevy Suburbans with 350 CID engines.

	=20

	When I got back to the house with them and cleaned them up, none
have the GM numbers that are listed as being for 350s.  In fact, all the
sensors have a number that starts with DR-699-#### where the # is a
number.  In addition, all of them have different numbers for the last 4
numbers (####).  =20

	=20

	Can anyone out there tell me what these numbers are for?  Do you
have a cross reference to the GM part #'s.

	=20

	Thanks for the help.

	=20

	Dave
