Many people upgrade from the S14 MAF meter to the Z32 item. This of course requires a remap. And it's a fairly standard item, so putting it in with the other bolt ons and the correct chip is fairly straight forward.
Given that it's going to be mapped from scratch, is it reasonable to stick the S14 element into a larger tube, or will the element still run up to it's limit too soon?
I'm guessing that this limit can be changed by putting the element into a larger tube - ie for a given amount of air mass, the element will be cooled less as the bore gets bigger.
