I thought they were spec'd for the N54: https://www.fcpeuro.com/products/bmw-direct-ignition-coil-eldor-12138657273#fitmentI believe the Eldor coils will need a dwell change if used on the N54. The dwell table on the N55's has the right settings as they use them stock afaik.
Ahh maybe, but I thought people were using the N55 part # for awhile just because "they fit"I thought they were spec'd for the N54: https://www.fcpeuro.com/products/bmw-direct-ignition-coil-eldor-12138657273#fitment
Lots of issues with this write up... specifically the "part 2" at least haven't read part 1. For one he is quoting injector mosfet specs and circling injector mosfets on the board, and talking about ignition igbt. He is worried about flyback voltage for the injectors (because that is what kills their mosfets) but he's monitoring the ignition system... that system needs the back voltage to push the primary energy over 300v, so it can get to 30kV+... he even says that happens but states it's too much, which is wrong, it's absolutely needed for the ignition (but not injection). It's why there's a 500V capacitor parallel with all the ignition coil voltage leads already. It's like he confuses or doesn't realize they are isolated systems. I think he's a smart guy but he needs to go over things again imo.
