Here is a comment from CZ in another posting -

"Colder plugs ( L10) also allows a LOT of advance to be used, as high as 30 degrees, with a significant power gain. I see advance gains of useful amount up to about 8 degreees, where it flattens out, then rising again at around 14 degrees and up.
Of course these plugs are horrible to use in cold air conditions, contributing greatly to flooding. Good for track use, but pretty useless on daily driving in cold weather."

My questions is would it be possible to develop a CZ map for the colder plugs to be only used in the summer time (or all the time in places where there is no winter), then during the colder months, put the stock heat range plugs back in and load the standard map?

Thanks

I'm wondering what qualifies as "cold weather" from someone living in Canada? Would it apply to someone whose coldest winter nights don't go below 25F (-4C)?
