Bobby, I've never used one of the dual sync set ups....what type of trigger is being used? Are both sensors the same (Hall effect,or VR type) ? Also your EFI controller does it have datalogging? If so does it indicate unusual engine speeds when the issue arises or a big change in injector pulse width? Or do you have other datalogging (racepak Ect.) that may show an unsteady RPM? I would think that if the crank trigger portion of the unit were acting up it would show up on a datalogger as a drop or spike in engine RPM. Joe
