Question:
2005 Land Rover Discovery3/LR3 AKL I pulled the CEM read the data with xhorse vvdi prog and wrote back to the 5th unused slot and wrote the data back to the cem with vvdi2. Now before I go to reinstall I am second doubting myself, should I be using a used slot instead? I saw another post where they say you can use a used slot, and then another post where if you use an unused slot you just have to learn key to car when you install. Any idea?
Answer: You can write to unused slot and write back to CEM, works perfectly with genuine 7936, not xhorse super chip.
