Each HTG GCU has the same features. There are no extra cost features.
GCU can control multiple types of transmissions including: DCT (BMW), DSG (VW), any Hydraulic with Torque Converter like 8HP, 6HP, GTronic (MB), NAG, PDK (Porsche), and others.
We are working on adding more and more predefined transmissions with accurate base maps to increase ease of use!
