I didn't because the stat sync was working....but I do know that it blinks on and off rapidly while running. Is that normal?...never actually paid attention to it

I'm pretty sure stat sync is supposed to read "on" when the engine is running.

Did you do this check?:

*** Nissan manufactures many different optical-type cam and crank sensors. These discs have different teeth patterns that, for the most part, are physically interchangeable with one another and can easily be installed upside down. If the vehicle has the stock cam/crank arrangement, the appropriate base map will work and there are no adjustments needed. However, if the engine has been tampered with at some point and is not starting with the AEM EMS, check the parameter Stat Sync'd?. If this parameter turns ON while cranking the engine, the cam/crank disc is correct and the starting problem lies elsewhere. If Stat Sync'd? stay OFF while cranking, log the parameter "S-tooth". Find a unique number here to synchronize from. In other words, there should be at least one value displayed in the "S-tooth"? parameter that only happens once per engine cycle (1 camshaft revolution). This value should be entered in the option "S-tooth". Note: Some Nissan cam/crank sensors will have multiple unique values to sync from. If a change was necessary, be sure to confirm the ignition timing using the Igniton sync option.
