There have been some laws passed about diesels, somehow the trucking lobby protects trucks. But marine diesels have some special requirements, divided into tiers with a difference between 'commercial' and 'recreational" diesels. Going forward, I don't think the validation can be done without an electronic connection. Not sure when that requirement would have started.
While I can understand some posters sentiment about not adding something else to break or complicate things, If it's there we should use it. If your engine can tell you it's not getting enough fuel
, or the timing is off, etc. why not listen?
