well ive done a few logs with it to see how the stardard setup fuels.
Quite interesting results.
When cold the idle is at around 13.9 to 14.5
Any throttle requests a greater amount of fuel bring the figure to 12.8 almost exactly everytime.
Then when the engine warms i get a nice smooth idle at about 14.6
Now the interesting thing happens on accelleration.
If i use 100% throttle i get an AFR mix of 13.6 ish but light throttle sees it a lot richer at around 12.8.
I'm guessing this is likely to be due to the 1.6 having an on off tps. so maybe full throttle will let more air in with the same fuel mix as part throttle.
Either way its highlighted somethng id been seeing with my fuel usage.. i.e. if i put my foot down everywhere i get much the same mpg as i do taking it easy unless im on the motorway holding a speed which the afr readings show the ecu does a nice job of finding 14.7.
