Graphing AFR or Lambda Error with double stoich e38 2 bar sd patched os

I've searched high and low and tried everything Ive found but cannot get error values that make sense.
Trying to dial in the sd tables. I have the 2 bar sd patched OS. The tune is scaled for larger injectors and MAP so stoich is doubled and halved IFR etc. I am bringing in the aem wideband via the ac pressure sensor. I have the math parameters in place to display/log afr and lambda and they look correct and correlate. But every math parameter I try to graph in order to get the error percentage for afr or lambda, I am getting very odd values populating in the graphs. With the commanded afr being double stoich and the commanded eq ratio not being actual lambda I am struggling to get these errors to compute. Ive attached the pertinent files so you can see what Im seeing. Thanks in advance.
