I have swapped an 0411 in my wife's 97 zr2 S-10 4.3. The motor is stock and I have been logging a lot of knock around cruise with a stock 2002 blazer tune. I then realized the blazer had the flat response type sensor and her 97 s-10 has a resonant 1 wire sensor.
I don't have any stock 4.3 files with resonant calibrations. I swapped all the knock sensor tables from a 2002 express van 5.7. Will this be sufficient or is there a better way.
She drives her truck on the interstate every day to and from work cruising about 70-75 right in the area I was picking up knock. I could hear an audible amount of knock before I changed the knock tables. While this fixed the knock i could hear I was still picking up knock and could feel the PCM pull timing at certain points.
I have logged and adjusted the spark tables as needed to stop the knock but the cruise areas are about 3 or 4 degrees below stock in some areas, is this normal? I am tuning for best economy at cruise and need to get this sorted out before I start leaning things out.
Thanks!
