MAGIC FLX2.28 Connection Cable: FLEXBox port F to DQ500

The FLX2.28 cable is a dedicated bench‑mode connection lead used with the F‑port on a Flex / FlexBox programming device (from MagicMotorsport).

It is specifically designed to connect from the FlexBox “F” port to the TCU of certain automatic transmissions — most notably DQ500 and DQ381 gearboxes.

Using this cable gives you:

• Secure, direct communication between the FlexBox and the transmission control unit.

• Faster data transfer and more stable communication in bench mode (not via vehicle OBD).

• Lower error risk when reading or writing to the TCU.
