AZSPEED has dyno tested several sand car engines from "Mild to Wild" 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.
