I'm impressed how quickly it fires off - I have an older BigStuff3 system which uses dual sync (cam and crank) for sequential injection but that in turn means the engine has to go through one and perhaps two full revolutions before it can fire off while cranking.

This one seemed to light off right away, which is much nicer!
