Mike Van Steenburg told me that you can attach a good OMP and tie it to the side of the motor and it will fool the computer to keep the motor running. I don't know how that works because I assume that the OMP is putting out a pulse signal to the computer to indicate rate of flow. It the signal generator goes bad then the computer puts the motor in limp home mode so that you don't burn it up rumming without the oil being injected. If you can fool the computer by attaching an OMP without it being installed and turning, then I would like to know just what the computer is looking for in a signal from the OMP. If it is a pulse like I suspect, then merely hanging a good one off the side of the motor wouldn't send out the pulses if it wasn't turning. If it is a pulse then I don't understand how the trick would work. Also if it is a pulse, it could be simulated easily and a foolproof way to satisfy the computer could be cheaply devised. You would need to pre-mix to preven engine damage in the event that your OMP failed and the computer was fooled by the simulator.
