I just want to emphasize something. What you are experiencing is not totally abnormal. If you set your WUR in the winter months it will be fine in the winter and a little off in the summer and vice versa. It’s just the nature of the WUR. It is not a super-sophisticated piece of equipment.

In my opinion, you have a few choices:

1) Live with it.

2) You can fiddle around with the calibration. Basically you want to move the pin just enough to find the sweet spot for cold starts. It may take a few tries.

3) You can make the WUR adjustable. Some have done this mod and have different summer/winter settings.

4) You can look into something like the FrankenCIS.

My car behaves better for cold starts in summer than in winter. I have to be patient with cold start in the winter. I’ve chosen to live with it for now.
