I forget. Look at the parameters/devices to see if the boxes are unchecked. It doesn’t disable these systems. It just suppresses error codes when you disconnect them.
As far as I know; Ulf Penner ist still working on his special tuned version, that correspond to All-Markets GT & GT Triple Black VIN from AV5457 and up
One hint:
I know, that it should be able to carefully copy ALL tuned ECU-Values from Ulf Penner tuned Maps for example from the TFC also into your original Rocket 3 GT Map (also for 31248.hex) to finally get YOUR self tuned GT Map-Version
It seems the Penner tune for the European Rocket GT (31012) is a stock tune and not modified. Etv3 tables are not 100%. Does anybody have the correct map with modifications?
