Mast Motorsports Ls7 Crate Motor Dyno
|
Mast dyno tests every crate motor that it ships. During the R&D process, Mast calibrates each specific combination at 160 different rpm and load points, from idle to redline. This involves painstakingly dialing in the air/fuel ratio using a modeled speed-density strategy that calculates airflow using throttle models, pressure models, and injector models. The M90 ECM also utilizes an octane-learn function that can adjust the spark maps automatically for octane ratings that range between 87 and 93. View Related Article
