So using toaf, can't we change Ecu ZCS codes and register?

Correct. I had to use T4.

Dougie.

I want to change this situation with toaf, zcs codes and save it to ecu, it fails.

There is more needed than just a ZCS code change. You need to do a full ZCS change, reconfigure the car and then download the correct engine tune, all using a T4.

Post your original ZCS codes in this thread, and can generate revised codes and checksum for you.

Greetings, thanks a lot for the reply.
Do I have a chance to do what you said with toaf?

Unfortunately not, you would need a T4 to download the new tune.

I downloaded a new tune earlier today via Apple music. Bet T4 can't do that.

Are you saying that the 2.5 map is in T4 and will be uploaded? Or do you take it from somewhere else and write to the ECM with T4?

When you change the ZCS codes and do a reconfigure the T4 will ask if you want to flash the tune.
