The computerized Fuel Injection systems like EFII and Eagle EMS.

I thought that most injection systems in our airplanes are constant flow, not pulsed.

When/which systems are timed to pulse this way?

I'd suggest the OP call Airflow Performance and take Don Rivera's class on fuel injection systems (Fuel Injection 101). He talks about both his system and his competition, and he does it very professionally manner. I took the class this spring and thought it was a very fair value - and the food and drinks provided were pretty amazing, too. What you'll get out of this class will really help you sort out the wisdom from the opinion that you'll encounter here and elsewhere. He covers the theory first and then has a lab where you can see how the parts actually work under different conditions. As an added bonus, Don and his wife Colleen are really good people.

FWIW, I had already purchased a Silver Hawk FI system for my IOX-340 and Don took the time to explain my system and said he'd be happy to work with me balancing the injectors even though I didn't buy his system.
