Understand that you are still in development. I'm just brainstorming possible applications.

I envision a spare injection hard line, re-bent to run to an injector aimed into a large glass jar. You could connect this to the # one delivery valve and just run the engine at idle on 3/4, 4/5 or 5/6 cylinders.

My timing light has an advance adjustment dial so I also imagine that while the engine was running with your trigger mechanism attached, you could adjust the advance dial and shoot the injector spray until you could see the very beginning of the injection event.

This exercise would tell you the exact offset between the position of the trigger lug in the pump and the actual injection event and would take into account all of the variables - actual port closure, hard line flex, pop pressure, etc...

Then, you could shoot the crank indicator with the freshly calibrated timing light and adjust the pump until the desired indication is reached.
