Right click on your fuel rail channel and switch it to mpa if needed. You should have pulsewidth logged also. Graph LTFT+STFT
You could also offset the o2 sensor data for the maf/ve lb/hr area decel sees to trick/force the car into a richer condition on decel. This would keep the car from pulling fuel and it would think you're 14.1 or 1 lambda but actually richer. Works the same when cars are lean vs the wideband reading and an o2 sensor calibration should be done for better stoich accuracy. It's all just mathematical equations that do different things. The options are there, but be careful to not do too much and wash the cylinder walls.
