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.
Would be interesting if someone actually confirmed that... I've been running the "N54" eldor coils for years in my N55. Original coils starting misfiring at around 100k and these Eldors have been in for another 27k. I have seen people saying Eldors won't sit down onto the plugs properly on an N55 and that isn't true so I wouldn't be surprised about anything else either.@jayoma did you ever confirm what the dwell diff for the n55 coils and would they work better ? I have upgraded on my n54 but now it makes me wonder for my n55 and n63tu
I think that is what is being asked. If it's an n54 coil then why did he have to carry over any n55 values? Or are the n55 dwell times the actual advantage? not sure what's being said but everything else I've heard about eldor coils so far has been incorrect so I wouldn't be surprised about anything. Or is Hydra saying why can;t N55 owners just copy and past in the N54 dwell tables???Is this really necessary?
