Not sure if my question should be a new thread? On behalf of a friend, fellow NNVI Inliner working with a stock computer, Vortec 4.2 in a 70's pickup trying to connect a tach. Any advice on aftermarket tach or junk yard tachs that would work with the tach output on stock computer? Hope I have worded this correctly? Understand that the signal from the computer requires some "translation". Hope someone's. "...been their done that" ?
I seem to recall seeing someone that has, OHC Firebird maybe? I can't find it in the search.
Marc would normally be the expert here, but IIRC he satrted out with his on Megasquirt, so not sure if he has 'been there, done that' as you say or not.
