Jed_dc2 Posted October 9, 2020 Report Share Posted October 9, 2020 In the process of turbocharging the b18c engine in my dc2 and want to run knock control for tuning and safety. Can I replace the stock sensor with a Bosch one, change the plug and use the existing loom or do I need to buy the expansion loom and wire it in myself ? Will 1 sensor in the stock location be sufficient or would 2 sensors be better still ? Will be running 9.0:1 comp on UK pump fuel 99ron with gtx3576 turbo if that makes a difference. thanks Jed Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 10, 2020 Report Share Posted October 10, 2020 One pin needs to connect to the stock knock sensor pin/wire and the other preferably to sensor ground. A single sensor in the stock location is sufficient. Jed_dc2 1 Quote Link to comment Share on other sites More sharing options...
Jed_dc2 Posted October 10, 2020 Author Report Share Posted October 10, 2020 Thanks I was hoping that would be the case. Whats needed for me to have an EGT sensor set up for logging through ECU can it be wired in directly to the expansion loom or do I need a controller to go with it like the wideband ?

dx4picco Posted October 10, 2020 Report Share Posted October 10, 2020 Only the Link Thunder has the amplifier needed for EGT sensor. Meaning for any other ecu you need a "controller" like you said, that gives either 0-5v signal to the ecu, or one that give the info over CAN bus Jed_dc2 1 Quote Link to comment Share on other sites More sharing options...
