The ABZ 4.2L V8 was found in the early A8's, and almost always was attached to an automatic tranny. Whenever a manual transmission was attached to the engine for a motor or tranny swap the ECU gets very grumpy without the proper signals from the transmission computer (TCU). This chip is designed to reprogram your ABZ ECU so that you no longer need any automatic TCU connections or devices.
This can be used for engine swaps that use the factory ABZ management, or an A8 with a manual transmission conversion.
