What maps could changing the MAF sensor affect? It looks like when I clutch in, it hits 14-15 AFR, then for some reason misses the idle RPM and increases load to compensate, at which point it stumbles and hit 10 AFR, then dies. It seems like it just doesn't make enough torque at idle even though the AFR is correct. At idle RPM, it looks like my fueling isn't too far off (fra_w is 0.994, frm_w is 1.05 at idle) so it's difficult to imagine running a little off would cause it this much trouble.

Fairly confident my MLHFM is close to where it needs to be, the trim heatmap tool shows that it's within 1% at almost every value that isn't at the edge of the graph

Stalling out happens at the end of the log, plus some other RPM drops that don't stall are in there as well, log file at https://drive.google.com/file/d/1V5PN1m6pdK9R38WeA5zjc0UjjeaL4fZG/view?usp=sharing
