ProECU License Key (DESkey)

Please note. DESKEY/Phone Flash does NOT replace the license. You ALWAYS need a license if the car is not currently tuned on EcuTek. DESKey/Phone Flash just selects the method for flashing.

USB DESkey which enables you to download and use ProECU on a supported Windows Laptop. Required for vehicles that do not support PhoneFlash and for certain vehicles that require it for the first flash (BMW).
