From a car? *How did you manage to get a car electronic ignition to
work on a merc? *Not saying it can't be done but why?


Why not. These I/Os are basically just auto/truck engines with
marinized parts where they might spark. (alternators starters etc)- Hide quoted text -

Yes, but the trigger and the trigger module are generally designed to
work as a pair. *And on boats there is no vacuum advance and often no
mechanical advance either. *All the advance is handled by the module.
On cars the vacuum advance was used because the engine load is not
consistent like it is on a boat. *Then all of that changed completely
when cars went to computerized spark controls. *Could you make a car
one from the era when cars still had them work, sure. *But it's not
just going to plug in to the thunderbolt connector.


I got the impression he was just testing to diagnose an idle problem.- Hide quoted text -

And I was asking how exactly he did that. He said he used a car
module. Well the only ignition module I know of that plugs into the
merc harness is the merc thunderbolt one. And you won't get the merc
one off a car. So I wanted more details. No matter why he did it I
don't understand how he did it.
