Can't get 2,000-3,000 rpm range to enrichen!

My AFRs from 3,000-9,3000 rpms are looking decent, but i keep trying to enrichen the AFR tables in the 2,000-3,000 but it seems to have no effect. any hints on richening up the 2,000-3,000 rpm range? I'd like to see 13.3 AFR / 0.90 lambda.

Also, all three of the charts below are with the same tune, yet the AFRs between 2,000-5,500 seem to be very inconsistent in terms of enrichment. it honestly looks like sometimes the ECU is trying to target 0.95 lambda, and other times it suddenly drops to the values more consistent with my AFR tables.

Up to 0.625 load you are targeting stoich. Would you mind posting the actual logs? These graphs are not readable unless you know what was logged, the only thing that I can make full sense of is the RPM really...
P.S.: I am no a rotary specialist, but are you trying to blow that engine up? It's pretty clear from the AFR and known retard tables...
