Computer on Otto doesn't appear to work - don't know if it is switched off in the system or something duff in the supply side. But judging by fill ups we did and distances he was nudging 20mpg, mostly gently driven but variable running, with the blow gasket making him a 3 litre V6. Looking forward to seeing what he does all working but the flu jab today has wiped us out for the day. Hope for more productive times tomorrow.
I think you can enable and disable with Nanocom. Need the buttons on the stalk, obviously.
