It includes an external Gasoline Direct Injection (GDI) controller, real-time fuel learn, an integrated 1 bar MAP sensor, and 4 programmable inputs and outputs.

To identify your version: 4-pin fuel pressure sensor = early version (550-1630); 3-pin = late version. The 3.5 in. LCD touchscreen includes a calibration wizard and tuning functions. Bosch LSU 4.9 wideband O2 sensors are included.
