I am a believer in preventative maintenance, of replacing things before they fail, especially those that can leave you at the side of the road.
I realize this is not always possible.
In this spirit, though, does it make sense to replace the ECU at a certain point rather than wait for the day it fails? How about other electronic parts that will fail?
Or is this a case where the lifespan has no rhyme or reason, and the replacement may be more a detriment to reliability than the original?
In other words, if not broke, don't fix?
Your thoughts appreciated. Thanks.
