Required Fuel Calcualtion Problem

I am running 2.3L Turbo with Direct coil ignition, I have MS-II V3 with 2.888 code. I have spark and my injectors are fireing under injector test mode. I had the vehical running and it run awesome at 1400RPM and above but terrable at low RPM, I currently cant get it started any more even going back to old MSQ's. My question is, I have 4 injectors ( low impedence) and I am using PWM and I have the injectors wired in in pairs and they are in parrallel ( 2 wired together, to pins 32 and 33 of DB37, and the other to in parallel and wired to pins 34,35.) As the diagram shows. What im wondering is does mega squirt think that I have 2 injectors instead of 4 because there in parallel? Can I tell is I have 2 injectors and add both flow rates? ( 30lbs X 2 so two 60 lbs/H injectors?) Should I run them simultainious staging because of this? How does this effect my required fuel? ( I have 2.3L engien, 30lbs/h injectors and 4 of them.)

You specify the number of injectors in the Injection Control window. Our 2.3 test mule seems to run better in alternating mode actually.

would I be able to take a look at the Test Mule MSQ to give me a base Idea as to what my settings should be?

I don't know if this will do you any good as this one had 14 lb/hr injectors, was running different firmware from yours, and did not get much in the way of serious tuning. But if you want the file, here it is. This one was one of the first beta Microsquirt installs.

Thanks Hope it helps. Im going right back to square one anyways, compression, spark, fuel, re read megamanual and build a new msq! I have over looked something and I hate just chasing a blind fate! This will keep me from wrecking somthing foolishly!
