In Belgium we have about 5° temps now and i guess since the cold-start map is not good enough i can only switch plugs no...?
The colder the plug the narrower the window of getting the cold start right and the cold start map should only be a offset of warm running,
But it can also be down to how much adjustment the ecu will allow,
Try hot stock plugs to see how it sets but do not drive it hard.
