So I have tuned a couple LB7 trucks now (01, and two 04's) that I logged and found the pilot injection (quantity and timing) to not be following what I put in as an input. Is this a common theme with efi live and the lb7?

I'm trying to require less pilot timing, and I can't seem to find anything that would limit pilot quantity.

Not an expert, but is it possible that B0753 Pilot Injection Coolant Compensation is coming into play? Pretty much zeroes out after 154 deg F and above though, so it would have to be a scenario when the engine isn't fully warmed up.

What I found was the dsp tables didn't respond to changes, it used the main table in all positions. But yes, I have also had problems with pilot tables tuning lb7's. I brought it up on the efilive forum a few years ago.

I agree got to look at those Multiplier tables
