Dont forget you have to adjust the base idle speed to make sure its stable with such low fuel levels. When you have it all correct you can unplug the ISCV and nothing will happen at all. NOTHING.

The ecu has a large voltage drop with the fans kicking in id say. Try a meter on pin 20 of teh ecu with fans off and on, see what you get. You want it to stay above 13.5v at all times ideally.
Try the same at teh fuel pump too, worth a check.
