Afternoon all,

On my GS300 2JZ build, I have upgraded my knock sensors from the old OEM ones to new Bosch flat response knock sensors. I’ve done this due to the fact that the entire bottom end was rebuilt with forged internals and I’m now running a lower compression ratio than stock. For the wiring into the plug and play harness to run the stock ECU in parallel to the emu black, I followed this video on YouTube: [url=https://youtu.be/ajXcXGA9NVo?si=QQM8rTLRR-OCxn5F]https://youtu.be/ajXcXGA9NVo?si=QQM8rTLRR-OCxn5F

how can I tell if these new sensors are working properly other than pretty much causing knock (which I do not want to do) I know the knock sensor setting has to change like the frequency and such.

Will I have to have my tuner set these up the rest of the way? I just want to know that I’ve wired them right and that they are or will receive a signal when they are supposed to.

More insight would be appreciated. Thank you all
