its strange if i were you i call them and they will help you, you just need the cable hooked to the ecu and your lap top and they will guide you trough the process, when i received mine it dit not have the startup file in it so it was cranking the same as yours as soon as i call adam up he told me what to look at,and then told me thad the ecu dit not had the startup map in, he mailed me the map told me how to load it up and the car started up right a way and i drove the car for 2 days whit out tuning nothing in the ecu the only thing i dit was set up the fuel press in the ecu the same as the regulator and change the injector size and boom she started like it was on the stock ecu
