I am swapping my 991.1 Sport Design steering wheel for a 991.2 Multifunction wheel using the gpsadapter modules (https://gpsadapter.us/products/adapt...12775062798422). The 991.2 wheel comes out of a manual car, so, no overboost. In that case the i mode controls the PSE, which I do not have. Any idea how to make the i mode PDCC?

In case someone want to retrofit cruise control in the 991 or 981/982/718 like i did yesterday.

To get it activated with ThinkDiag you need an activation code (which you can find through google and order for 100USD) and put it in the Steering Wheel Electronic Control Unit (Special Function -> Function Enable)
And of course you need to buy a used steering column switch with the cruise control stalk on it. Maybe you also need another steering wheel angle sensor, but it was not necessary for me at my 718 (with PDK, Voice Control, SportChrono and Board Computer).


On top of that you need to activate the Cruise Control Options in all coding values that you can find (you can search for "Cruise" within the coding-function). Important are these three control units:

• DME Control Unit
• Instrument Cluster Control Unit
• Steering Wheel Electronic Control Unit

No PIWIS needed for it.
