I would use 4 "ignition outputs", requires repeating the dual out pattern twice on your 4 cyl engine and also the trigger reference tooth table (0,30,0,30).
At the bottom you have defaults for some settings, apply for "Wideband settings" dialog.
Use the "MAT/TPS enrichment" from my config, your's does not add enough with colder temperature and adds too much with hotter temperature.
You are using very modest acceleration enrichment (dTPS/dMAP table).
You could use a lot more afterstart enrichment.
TPS threshold for idle 5% is quite high. Usually set to max 1%.
MAP calibration seems off, check F1 for help in "ECU calibrations dialog".
If you are not using ECU logger, turn it off.

Check out this BMW M50 config file for reference.
