Subject: CO Trim how is it stored Tue Dec 10, 2024 2:50 am
Somehow search does not really work for me, so maybe asking a question which has been answered already. When i do change the CO Trim with Guzzidiag is the change stored in the non volatile memory of the ECU, or are the changes lost when i disconnect the battery during winter time ?

Are you using an open loop map? If you are still running a closed loop map changing the CO trim won’t matter at all as it has no effect.
With regard to whether removing the battery will void the setting? No, it won’t.

OK, it’s an open loop map so yes, changing the CO trim will have an effect and no, disconnecting the battery won’t clear it’s current setting.
