programming LS2 flat response knock sensor for 01 5.7 I'm working on putting a LY6 6.0 into my 01 T/A and want to use the LS2 style flat response knock sensors that bolt onto the block in OE knock locations.
What programming trickery needs to be done in order for the 01 5.7 T/A pcm svc#12270411 to be able to recognize and properly utilize the newer style knock sensors.

The stock LS knock sensors are resonant sensors and the LS2 knock sensors are flat response sensors.
How do you make the LS1 pcm select and recognize the different style of sensor?
After that shouldn't it be a matter of loading the knock tables from a LY6 6.0 truck into the LS pcm? Or is it not as simple as cutting and pasting from one tune to another.

In EFI Live you can change the type of knock sensors you have in table (B1402). I have always used EFI Live when I did it. I dont remember seeing the table in HPT. I will look tonight and see if HPT has the table.
Every time I've tried to change the sensor type with an LS1 PCM it never seems to work correctly no matter what. Even though the option is there in EFILive I have to question whether it actually does anything or not.

I have put LS2's in several camaro's and the used the ls2's knock sensors on all of them. The knock sensors defiantly worked on all of them. Were you messing with LS1A or LS1B pcm's? All mine were LS1B (99-02)

I used adapter harness for the knock sensors, I don't remember re-pinning the PCM but I may have being I had he harness out and usually re-did the injector plugs.

you must also have the correct settings for the knock sensors...
Well you got half of it right, the correct settings are required. Now what are the correct settings is the question seeing as how there isn't a calibration out there that matches up. Been there done that, tried everything and nothing was consistent. Between false knock and not registering real knock I couldn't find the fine line which tells me there is more to it then what's in any of the editors.
