To use the module, the purchase of a USB security key Bitbox is required. The key can be purchased in our store. One key can activate an unlimited number of modules.
Module activation is performed within 1 hour on business days (usually 10-15 minutes). Activation may be delayed on weekends and holidays (up to 2 hours).
For module activation, ONLY the serial number of the key and email are required.
To work through the OBD2 connector, a J2534 adapter is required (Scanmatik 2, OpenPort 2.0, Dialink, Mongoose, etc.). More information about J2534 here.
To connect the control unit on the bench, additional equipment needs to be purchased, any of the following:
