Looking for a square wave RPM output signal on our cars for my TurboSmart Eboost2 controller. I tried tapping the coil pack wire but it doesn't seem to put out the correct signal. It produces a vert choppy erratic reading. Contacted TurboSmart and they said I need a MSD or Autometer tach adapter. Has anyone installed one of them before? Here is a similar thread explaining my issue: http://img.modularfords.com/threads/183054-eBoost-2-Controller-RPM-Signal Only difference is his car is an '08. Thanks in advance!
