Watch a small excerpt from one of our GM Master Tuning Experience live classes!
These live classes are twice a month and you get access to an instructor to ask questions. 

In this video, Bob is discussing injection timing on direct injected vehicles.  One of our students asked the question about when the injection window could be.  Bob goes on to describe that you can technically start injecting at the end of the exhaust stroke and then all the way through the intake stroke, but as the compression stroke begins and leads to combustion, the fueling window closes. He also discusses piston speed as it relates to injection timing. Check out this video for the details.
