Pointing an oscilloscope in the general direction of the output of a coil won't tell you the full story, coil efficiency and voltage output would perhaps be a more important measurement. I like to test things like this in the real world, no amount of bench testing makes up for a good hot load test at high boost and running rich.
Personally the timing drift associated with mucking around with dwell on these scares me. I would prefer something that just drops in and allows 40psi at 1.1mm, like the Yaris coils apparently do. I will give some real world feedback on them soon seeing they are in and running fine on my evo.
After running my original 13 year old VQ coils to 40+psi I have great respect for them, I don't suggest them for any other reason other than they work, I have nothing to make out of it...
