Sorry, can't offer any answers, but a company called Equus (I think) used
to sell a digital tach, oil pressure, temp, etc unit.  I have it somewhere
although I never used it.  I think that a wire went to the coil, and there
was a switch for 4, 6, or 8 cylinders (I guess Diablo owners are outta
luck).
