Phil2JZ Posted April 21, 2022 Report Share Posted April 21, 2022 Hey guys, I’ve upgraded my stock 2jzgte single wire knock sensors to the Bosch donut style two pin KS4-P. I’ve attached the second pin to sensor ground. The kit came with two block studs for the conversion. The engine is already tuned at 650WHP with the original knock sensors at 6000hz frequency narrow band. My question is, 1: Can I leave it at the 6000hz narrow band setting and all be good? Would the knock system work exactly the same and just focus on the same selected frequency for its knock detection. I can move it to double the frequency to help with engine noise, 12000hz etc. 2: Do I need to re-adjust my knock threshold? Now that I have new sensors. any help would be amazing Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 21, 2022 Report Share Posted April 21, 2022 6Hz will likely work ok. The threshold and gain etc will need to be tuned from scratch and validated. Quote Link to comment Share on other sites More sharing options...
