Yep
I have Bill Bailey's or maybe lerch's or maybe both.
Bill couldn't get it working.
I've had no problems. I am using it for developing a frontal ignition system.
It has to be connected to a puter which isn't hard to do. Everything is USB.
Pressure curves are pretty revealing. However, unless one is really interested in more detail than is really needed the standard extraction, primer signs and a chrono are pretty darn good.
The company is good to work with. The tech guy, who hangs around here at times, is available and knows his stuff.
I learned about magnums and secondary pressure spikes while using it.
I'll be revisiting the FI shortly and will have more info one of these days.
