Latency is a measure of the amount of time it takes for an injector to fully open once it receives its signal to fire. It is usually measured in milliseconds or microseconds and is an important parameter when tuning. Other terms synonymous with latency are dwell, offset, lag, etc. We generally use the term battery offset. Our General Characterization Summaries include battery offset at various pressures and voltages. These summaries can be found in the Resources section of our website.
