Default Datalogging plan

After hours of reading through posts I believe i've got everything straight in my head as far as what I need to do. Here is my plan for datalogging, please let me know if i'm leaving any gaps.
Engine is a stock D15B7 with the stock P07 ECU modded to accept chips.
I'll be using cromefree to write fuel and maybe timing tables.
For data logging i'll use Freelog.
I'll pick up a Hulog for connection from ECU to my PC.
For wideband i'm going to pick up an LC-1.

If I wire the LC-1 wideband output into the ECU O2 input will I be able to log A/Fs through the ECU into freelog?

Will the wideband output make the ECU happy or does the ECU need a narrowband input? I would rather not have to install another O2 bung.

Please help me fill in any gaps i've left in my plan

Thank you all for the tremendous amount of knowledge shared on this site.

YES, you have exactly what i have except i have a p28 i think. THe ecu will be happy, by turning off "check sum" in the crome options i believe or just turn off check engine light for 02 in the options. YOu will be able to datalog fuel ratio in freelog as i do it all the time.

no extra bung needed, just put that lc1 in the closest one to the turbo or what would be considered the sensor 1 bung.
