NorPug Posted April 24, 2006 Report Share Posted April 24, 2006 Have just installed Haltech E6K standalone engine managment on my turbo. I'e been trying to hook up my original tachometer with no luck. So now I need to go to two steps back and find out how it works before I go any further Does anyone now how the tachometer works. Were it gets it signal and what that signal should be like. I suppose I have to make an adapter or something to make it work. But now I don't know were to look. The haltech unit have a 5v output as tachosignal. Any help is good help Quote Link to comment Share on other sites More sharing options...
NorPug Posted May 2, 2006 Author Report Share Posted May 2, 2006 On the backside of tacho i've found a plug with tree wires. On + on - and one shielded one. I suppose that the shielded one is the tacho signal. Does this come straight from the ecu or the coil? Quote Link to comment Share on other sites More sharing options...
