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...
Guest Dave Posted March 2, 2008 Report Share Posted March 2, 2008 Hate to dissapoint you but the lem does not have a knock input only the linkplus you could try bringing it into a ANvolt channel and just view it as a raw value but this will be next to useless for detecting knock if you want / need knock control you will need to upgrade to a Linkplus G3 Regards Dave [email protected] Quote Link to comment Share on other sites More sharing options...
James Wingfield Posted March 2, 2008 Author Report Share Posted March 2, 2008 OK thanks, That's not come as a total suprise. I guess I'll either have to look into geting something else that will display knock, or work out how to de-code the signal before sending it to the ECU.
