Engine and sensor functions are all monitored and can be recorded with key information available on the tuning screen via the dashboard functions. The FAST system also has useful data-logging capabilities. Base maps are provided, which should get you going, once the menu-driven engine setup settings are completed. Fine-tuning dials it in, as Westech's Tom Habryzk is doing with the fuel table for our 454 here. Various tables control all the required fuel and timing functions, with a variety of options on how to change the settings and by how much.
