A noob wanting to returning E85 135i with N55 back to Stock map
Hi,
I have an E85 135i and looking to return the car to stock.
The car has MHD tune and also has JB4 installed, which was carried out by the previous owner. I want...need to take it all out.
Are there specific steps I need to take to accomplish this? Can I remove the JB4 unit and then remove the map using the MHD app and return to stock map?
I've never really played with this stuff, but I want to make sure I can remove everything and have the car in its out-the-box status.
Thanks
