After completing my engine harness and set up in my AEM Infinity I was able to get my engine started but seems like it takes longer than normal to acquire sync state ~2seconds. This may be a by product of my Holley duel sync distributor not having great resolution but figured Id ask if this something I can improve. Video below showing delay.


Is the fuel pump sufficiently primed so that there is fuel pressure when you start to crank? Sometimes if there is no check valve, the fuel pressure can drop after priming, and it often takes 1-2 seconds to build fuel pressure.

Can you post a saved session with a few starts it it? We can look at the settings and see if anything might be improved.

Fuel pressure is good @45psi before cranking. ill capture a few logs and post up.
