If you have not found the solution and if I am understanding you correctly (when you say OEM remote), then maybe I can help. I have installed the EVO ALL with the T harness and an RF kit (Fortin RF642W) on my 2008 Infiniti G37S Coupe. I now have the option of turning on the car with either the RF remote or the factory remote (I believe that is what you mean by OEM remote). In order to use the factory remote for remote starting the car the lock button must be presses three times. Option D1 on the Flashlink Manager must be selected.
