    so i did a B17 swap into my delsol and im running a jdm p30 ecu (i know its jdm it came from japan with my jdm b16 head) so i wired the knock sensor into the ecu at pinout C2. the knock sensor was used but the guy said it worked when he took it out. Is there a way to test the knock sensor to see if its working or what can i do? i need to pass deq soon so is there a way i can by pass it for now?

    Did you ground the shielded wire? Second make sure that the pin in the ecu is in all the way. When I did mine I kept getting the same code. I went and rewired everything and when I got back to the uce I realized the pin wasnt all the way in.

    The pin that goes into the ecu itself. When I put mine together the pin wasnt making contact with the ecu. As the shielded wire goes, one of the wires has a metal shield around it inside the plastic. Ill try and get a pic in the am.
