Subway eat fresh

Hi! Im using greddy e-manage ... We got some results, but it still does not get the rpm signal right. Yes i have read that article, and i have an MS1 v2.2 on my other car (Vr4 Galant) but it was little hard to install. We wanted to test a piggyback before installing haltech or other stand-alone ecu. And If we put the stand-alone Ecu we are going to put the ignition on it too, subarus ignition is kind of old. Greetings Virta

Hi I am new here on subie forums... I,ve got problem with installing "piggyback" computer to my subaru rx leone turbo 1987.. It has 4 plug ecu cable, and the problem i,ve got is that i dont know where i can get the tach/rpm signal for my piggyback. It need tach/rpm signal for working. So does the 4 plugs what goes to ecu have this tach/rpm signal wire? And if it does what wire is it ? - Greetings Virta
