Again according to the ad copy, the pulse is supposed to be hotter and bigger, but I don't recall seeing any mention of the spark's duration, which seems important to me. I'm also curious as to whether it might do damage to a multi-spark ignition system.

I once installed a Jacobs' ignition on my SBC. They tout variable spark generation based upon the load on an engine, so maybe this is a more intelligent implementation of the same basic principle. I can't say that I noticed any performance or economy gains with the Jacobs unit. It did look kewl and had some nice bells and whistles, like a valet mode that limits rpm to, say, 1500. But I sure did burn through a lot of caps and rotors!!!!! Even when using supposed 'high voltage/high performance' (yeah right, it is still the same dielectric path because that is fixed by the shape) parts.
