There are lots of tables that modify the timing tables. IAT, coolant, humidity, mixture, etc. You can switch your wideband to read A/F ratio instead of Lambda if it helps to better understand what your car is doing. Log fuel system status-that will tell you if you are in closed loop or open loop. If it's in closed loop, it's going to try to run 14.7:1 air/fuel which is 1.00 Lambda.
