LMM timing limiter and pilot issue

[camcojb]

I've got the MPI twins on my LMM. Fantastic kit. I got the tuning from Rob and he's been great, but there's an issue that neither of us have solved yet.

We turn the pilots off in the tune above 70% tp or so and 2500 rpm up. But you datalog and the pilot is not off, sitting at about 240 US and 3.5 mm3. So you go into fuel pressure, and set the max number of pulses from 13 volts and 2500 rpm up to 1 (only allows the main pulse). Great, pilot is now off, but it now activates a timing limiter. On my truck it stops at 22 degrees max, no matter what is commanded, max allowed, etc. One interesting thing is that from a roll on in second gear I will shut the pilot off and get my desired 26-27 degrees, but once it upshifts and loads the motor it sets on 22 degrees and will not move regardless of rpm.

So it seems I can either have the pilot on and timing, or shut it off and lose timing. Thing is I want the timing and the pilot off, makes a big difference. I am guessing that there's a timing limiting table that references boost, and we do not yet have access to adjust it. We have the max desired boost set to 400 kpa, the most EFI Live allows. The truck is making 50-55 psi of boost on a run.

Any thoughts, Ross, or anyone?
