https://www.summitracing.com/parts/msd-8222
R = 0,7 Ohms and L = 8 mH.
And even if the DME varies the coil dwell time, at 6.500 only approx. 2ms are available for coil saturation, and cause of this my maths and comparison above do makes sense that at 2ms the result is 33 mJ.
So .... Did you measured diff. values at the MSD 8222?
Cause if your values above are actually the real ones thenwith 2ms an energy at the spark of 45 mJ occurs which would be enough then. |

You can always order a 8222 and measure it yourself.
