Arizona Speed & Marine has dyno tested several engines packages from "Mild to Wild".
Marine upgrades kits improve performance through out the RPM range. We have programs that have been developed on the dyno and on the water for bigger cam and superchargers.
Since MEFI 1,2,3 Delphi ECU's are not in production we developed conversions for the MEFI 4B to upgrade the older Marine systems.
We have calibrations for LS1, LS2, LS7, as well as supercharged LS engines.
We recommend InGenius software and MEFI 4B ECU. Included in the ECU is a calibration so minimizes the time to finish the final tune.
With the optional "Wide Band Closed Loop" the ECU will automatically make changes based off Target Air fuel MAP to keep the engine in proper tune for maximum performance.
