Hot weather starting problems

Please excuse the brief intrusion of a Honda enthusiast in your forum!

I run the FAQ for rec.autos.makers.honda and over the past couple of
months we have been getting the usual spate of questions about hot
weather starting problems. This is a known Honda foible and we have
the answer ready. Occasionally however we get the odd Mazda owner
asking the same question, and I have no idea if other Japanese
manufacturers use the same main relay system that has so long been the
cause of such problems in Hondas.

Here is a FAQ on the subject:

Does any of this apply to Miatas? Mazdas in general?
