Adjusting for oil temperature

Hi, over the last while I’ve been setting up my autosteer and I finally feel that I got it to a fairly good place.

Last weekend I spent a few hours spreading fertiliser, the auto steer (u turn specifically) was perfect for the first hour or two but after that it began oversteering.

I am putting this down to the oil temp as the steering is noticeable harder while cold.

Does anyone have any ideas? I’m currently thinking of making two profiles, but I’m sure there is a better way.
