hi i made a data log showing my rpm signal dropping out . my signal comes out of my ignition module on to pin 30 optin+. then i changed it to my coil negative and datalogged that [worse]. then i changed it back to ignition module tach lead now i dont get a rpm signal in tunerstudio at all. i disconnected the ecu and checked at the ampseal connector with my multimeter and the signal is there cranking??? any thoughts???
