Hello guys,
I'm planning to build a complete new engine wiring for a BMW N62B44 V8 engine. I was thinking quite a lot about how many relays should I use for it?
The original construction has 3 relays for the base functions (main relay, EFI relay, Ignition relay) and it has 1-1 additional relay for the variable valve lift.
Should I keep the OEM approach or can I simplify to 2 relays (ECU main relay + engine relay). (I'll remove variable valve lift, but keep variable valve timing)
What are the pros and cons? For me it seems it's only because of the relays current rating.
Thanks for the tipps!
