is that possible wastegate screampipe make noise to knocksensors? On my engine screampipe goes under the engine. I think that because at same time when wastegate going open knocksensors voltage rise notably. I can send datalog if someone want check.

Problem solved. I didn't know that I need configure knocksensors to ignition events.. now these sensors work perfectly

I have two Bosch 0261231006 knocksensors on my 1jz. Feedback voltage is 0v all the time. I tried change gain but anything happend. Anybody else have same sensors? I checked wiring and mounting these are ok.
