Reply to "MSD 8920 Tach Adapter without MSD 6AL"

...just curious, does the "Multiple spark" confuse the tach? I have my doubts about whether the multiple spark does anything, and the good news that at higher RPMs (maybe 3krpm) it drops back to a single spark. Its possible that the energy in the spark only 'registers' once, but might connection at the coil inflate especially the idle RPM?

(its been 20+ years since I've read up on this, but the conditions to really get a spark and propagation of flame are really pretty narrow and there are unlikely to be second chances...).
