racerxve Posted October 22, 2018 Report Share Posted October 22, 2018 Hi Everyone, What sort of values are you using as knock targets for 2JZ standard knock sensors? I am currently using the below values, my sensors read up to 900 sometimes at 7000 rpm. No audible knock on the dyno but then again, vented wastegate etc, the car is very loud and hard to hear. running GTX3582R at 18psi. setup at 6khz frequency (narrow band) RPM 3000 3500 4000 4500 5000 5500 6000 6500 7000 420 515 605 700 700 700 800 800 800 420 515 605 700 700 700 800 800 800 420 515 605 700 700 700 800 800 800 420 515 605 700 700 700 800 800 800 420 515 605 700 700 700 800 800 800 420 515 605 700 700 700 800 800 800 Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 23, 2018 Report Share Posted October 23, 2018 You cant really compare to anyone else's engine. The amount of noise an engine makes will vary with bore clearance, valve lash, ignition timing, boost pressure, etc. On top of that the knock gain settings will scale the volume up or down too.

jzx_jake Posted October 27, 2018 Report Share Posted October 27, 2018 My sensors also pick up a lot of noise above 6500rpm (2jz) The way I like to set it up is to log knock level on all cylinders during a pull with overly conservative timing, you’ll have a good baseline for normal engine noise. You can also use the high rpm lockout function. Quote Link to comment Share on other sites More sharing options...
