You can use a volt meter on the o2 wiring and see if your voltage goes up and down , it takes anywhere from 30sec to 3 min to go closed loop , car starts in open loop then switches to closed loop
Spend the datalog money on a xcal3 then you get a custom tune , datalogger and checks and clears the CEL or find some on here on FF close to you that has a xcal and do a datalog and I will be glad to look at it for you
