I am trying to find out what dwell i need to run these coils to keep them from catching fire when I go full standalone - I am thinking if they're anything like the Bremi coils they will be 3.3 ms, but I don't want to guess it.

The full part number on the coil looks like this:
0 221 504 410
1 748 394

Haven't found any tech sheets for it yet, any help?
