Injector “lag” time is the time it takes for an injector to open (OT) form the time it has been energized until it is fully open. There is also a close time that you do not hear about very often (CT). Some engine managment systems require you to enter this time and refer to it as injector lag, latency, delay or other terms. Although the times can vary slightly, the following chart should give you a good starting point. We will not be held responsible for any misinformation contained on these pages.
