I just switched over to E85 and I need to do some additional VVE and MAF cleanup. The CALC.BEN1_E38 PID won't work because the AFR data coming from the EXT.W02AFR1 is still calculated at 14.7 stoich and not 9.77. Obviously I need to use the EXT.W02LAM1 data. Shall I just create a custom PID and divide the data from SAE.LAMBDA? Is that the best approach?

Thanks!
