Good Deal On A Nice Timing Light

That looks like mine, which does work with MSD.

The funny thing is....when you get one that works with MSD, I suspect you are essentially buying a 'retarded' version of a timing light, one with a slower response rate. By slowing down the rate of sampling, it can't detect the multiple sparks and only sees the 'big picture' of the 4 events per revolution. It's like buying a slower computer so you can enjoy your **** for longer.
