Pilot shuts off in LB7's at 75MM3 of fuel or 2700 RPM's in stock tuneing. LLY's shut it off at 80MM3 of fuel or around 2800 RPM's from what I have found(I don't do much LLY, and would like to do even less of them if I could). I shut mine off around 2400-2500 RPM's with fueling in the 70Mm3 of fuel range. I shut it off sooner and it helped the turbo spool better, but rattled like hell when running my tow tune. I've posted about my issue on EFILIVE's forum trying to see if they can help me fix my pilot timing issue on the DSP side so I can shut it off sooner on some tunes and not in others.
For an LB7 with a DSP2 go in and set B0750 to 0, and set A0104 to all 0's for the cells, then you will have a selecteable pilot shutoff. Just remember to set both your pulse width tables in the DSP side to the amount for the pilot disabled since you will no longer have the pilot shot figured into the injection amount. Haven't found a way to do it for DSP5's since the DSP pilot injection timing tables don't seem to repsond for me. Got a thread over at EFILIVE's forum about it. Otherwise go into B0748, and set it to a number below what you have in B0750 for the cells where you want it to shut off at. Any amount less than around .925 will shut pilot off also as the injector latency is roughly this long(the injector will not actually open even though the solenoid is energized because this is the amount of time it takes for the solenoid to actually energize, open the return port, and create the pressure differential to make the injector open and flow fuel). Reducing pilot earlier on, and even shutting it off at the beginning of when it comes into power I found can help with turbo spoolup, but at the cost of increased engine rattle.
