I took it apart tonight and tried to figure it out. It has two solenoids. Best I can determine, they take the place of the mixture adjustment rod assy. on the 13b OMP. In other words, they move the barrel valve in and out, changing the oil flow. With this figured out, I could probably make it work for my purposes by locking the solenoid plunger in the fully open position. Or, I could try to figure out what the solenoid's nine wires do and then design a circuit to control it based on MAP, RPM, etc. Since I'm not an EE or a programmer, that isn't likely, so I think I will just lock it open and use a little more oil. BTW, the 20b OMP has 4 outlets, but one was plugged at the factory. So, it only uses 3 outlets. I think in the long run, it will be easier to use the 20b pump, and it should be a better match than the 13b OMP. I may try a flow test if I can figure out how fast to spin it to simulate 7000 rpm. At least I could compare the flow of the 13b to the 20b. Tracy - can I exchange the 13b OMP adapter (just arrived today) for a 20b OMP adapter?
