Tunerpro data tracing + emulation

Need some advice on data tracing with emulation with WBO2 on EGR A/D input of 7427 ECM. Beside having the VE table on screen, is it appropriate to have the AFR history table on the screen at the same time such that VE table values can be changed to achieve desired AFR? What two items need to be shown on the Tunerpro screen to accomplish AFR tuning? Please advise. Thanks.

Got the data trace working. Next run is to add emulation. In addition to data tracing VE table, for AFR, need to know what selection should be made to faithfully display AFR at the same time as data tracing VE, such that VE table can be modified while emulating to see difference in AFR. Anyone care to pipe up and make a suggestion? Thanks.
