So I'm planning for my Megasquirt 3 install. Looking at 12v supply for coils and injectors. The stock EFI relay looks to be perfect for the job being it's tied into a fusible link and it's stock purpose was to provide power for injectors.
I'm looking to run individual LSx coils, best I've found is guys recommend 15 amp fuses per bank so 4 coils and 4 injectors. Obviously I'll only have 3 each per bank. Anybody familiar with the EFI relays supply abilities? Could I power both banks from that one relay/fusible link? -
I am pretty sure those are 20amp relays.
You could replace it with a Bosch-style 30amp relay pretty easily,
just de-pin the plug housing and slide the female terminals onto
the Bosch relay's corresponding male terminals.
Some heatshrink would be a good idea.

That should be easy enough. I need to figure out what the EFI fusible link is good for. -
I think I'm just going to eliminate the EFI relay all together and install a 80a battery isolator, then have that go to a fuse block that is strictly for the injectors and coils. I think that will be a more robust solution and still be minimally invasive.
