locked timing and DESMAF_PID_N
Once into a warm stable idle, timing seems locked at 20 deg and only ISC is responding to control idle. Also, no matter how I adjust ITHBMA, DESMAF_PID_N is always 0. I should be using the default patches in A9L2, so should be using the expanded spark FN841XX to adjust timing with RPM delta. Any guidance or direction appreciated.

Yes, it is -1. i set TRLOAD to 0 and now it works. Still trying to figure out if I should set to 0 or 1

I'm trying to figure out why crank spark is at 0. SPK_UNDSP is set at 10.
