Doesn't seem to me to be any benefit from it unless you put the split shot injectors from an SD in with it. If you were gonna tune the SD pcm with a chip to run single shot injectors, may as well just leave the OBS pcm in it I would think.

Thanks to your help I got it wired right! I still needed to solder the connections before I left. I think the IDM is fried, or hell, could just be the CPS. I bought another IDM to test/upgrade when I get back. I should probably test for continuity too. Quick question on the turbo, when I'm cranking, how hard should it be sucking in air? Gotta go to work, but I'll be back on about 8am your time.

Since SDs have e-fuel, is the electric pump controlled by the PCM? That might be the only advantage to an SD PCM, but even that is probably not worth it since you easily wire up an electric pump like MOOSE MACHINE did and get the same get the same effectiveness as a computer controlled pump.

OK GUYS I NEED HELP HERE
I spent a few hours in the barn tonight getting everything ready to crank the engine over. Always wanting to be on the cautious side I decided to go the route of pulling the gps to spin the engine over without a load to let it lube itself up real good before actually starting it. However, it never lubed!
I had a multimeter hooked up to my e-fuel oil pressure switch at the oil filter hoping that it would show continuity once pressure was established.
Well, it never did and the HPOP reservoir never got oil to it (dipstick check)), after about 2 mins of total cranking (though only 30 seconds of continuous cranking so as to not burn the starter)
So my question is: can anyone confirm that just the starter spinning the engine over is enough to draw oil up the pickup tube and build low pressure thought the engine? Or do you have to fill the HPOP reservoir to get the engine to start so that it can spin fast enough to create low oil pressure?
...I sure hope I'm not int he same boat as Nick with an oil pump problem...
Oh and like him, my 3/4 pre-filled oil filter never got any fuller :-(

I'm almost positive the starter spins things fast enough to pump oil with the LPOP. It's a gear rotor pump so it shouldn't really be dependent on the cranking speed. I also know I have started them in the past without doing all the bleeding and priming that would have been necessary if the LPOP wasn't pumping until after it had started. I hate to say it, but I think I would take a look-see at the LPOP.
