but the next obvious reason is your Intake temps calibration was not adjusted. it is a simple table that you have in the Fuel section section of Uprev. Unless its a Pro feature only which i do not know, the file below is the ROM i had for my 7AT as an example.

Then ofcourse there is a separate Fuel Compensation for Cold which is used if the Coolant is below 70-75C (158F-167F) then it will switch to the main table.
Yup ! You're right , it's just that map.

I must adjust twice at year the compensation map....

Seems that the MAF does not read very well...

Obviously, the MAF are mounted correctly.....
