07spec_b Posted June 12, 2013 Share Posted June 12, 2013 I got a new shortblock installed. I logged the car after break in and it shows a constant -5 deg of knock after about 10% throttle even with the sensor off the block or unplugged. The tuner said its mechanical and didn't want anything to do with it. I went to the builder and he couldn't figure it out, said he will make some calls. Now all I hear is crickets. With ignition on I have 3v sensor unplugged and 1.8v sensor in. Knock sensor has 540kohm resistance. New sensor shows the same. Any input would be much appreciated.
