I always log when my car is running so yeah i do have the log files. But i don't understand your question about if the trace closely to the closed loop afr?
First there is no closed loop afr, you have set the afr targets as you want across different RPM's and engine load, for example my car is targeting an afr of 16.7 at idle because at 14.7 it was way to rich (could smell and see the fuel out of my exhaust)
Second you set the closed loop control as you want. Mine is set to be only in closed loop below 3000 rpm and below x load.
I can run the car completely at open loop if i want, everything is dialed in to be around 5% of the target AFR i want.
