My observation from having run EDIS waste spark for 10 years in my SC until last year converting to dual M&W CDIs and coils, with a 12 point JB distributor is I could not detect any difference. Sorry

EDIS inductive ignition is cheap and very easy to install and set up. As opposed to the current setup which was expensive and gives less freedom in the ignition tables wrt rotor phasing.

Engine runs beautifully but if there is any improvement I can not feel it. At least it is not significant in my car. It appears to me that inductive ignition may work pretty well and that CDI may work well too. At least with EFI in my engine.

I like the looks of those two shiny black M&W CDIs and the beautiful JB distributor is worth some and no regrets. But I could have taken a cruise in the Caribbean instead or bought a seat on the next space shuttle. Not that I would want to
