James Wingfield Posted March 1, 2008 Report Share Posted March 1, 2008 I've got a LEM G3 for my MR2 Turbo and I'm about to wire everything up but I'm not sure how to deal with the knock sensor. I have a std sensor already on the car which (I believe) functions by constantly outputing a varying voltage. I need to monitor this voltage and identify whenever the frequency of voltage variation has a component at ???Hz. (I'll find out what the critical frequency is but can't remember it off the top of my head). For now it's not important as I just need to know which input to use for this and if I need to modify the signal before it gets to the ecu. How should this be wired in and does it have to go in as Analog Volt 1 or can I use DI for this? Unfortunately I'm on a laptop with Vista at the moment so can't get the PCLink software working. There may be some tips in there that I haven't seen. Thanks, James Quote Link to comment Share on other sites More sharing options...
