Hey people!
So, variable fr_w shows us current AFR (o2 sensor) OR this variable shows us by how much o2 sensor corrects fueling??

For example at some point I get fr_w = 1.1. Does this mean that my AFR was 16.17 at that point? Or that my o2 sensor made my AFR leaner/richer by 0.1 (10% correction)??

Also ldrlms_w (ChargeLimitEngineProtection) gives me weird readings (values of 108-118). Shouldn't they give me values that I've put inside kfmirl and ldrxn maps??

No. ldrlms_w is ouput from 2D map LDPBM and is based solely on RPM, however it should only be considered in calculation of rlmax_w in the case of EGT, IAT, coolant temp, oil temp, and engine temp from cluster faults.
