Don’t the icu and an auto box learn how you drive and adjust the fuel mixture, throttle response etc to your driving style.
In my case that means getting every horse out of it and look i do treat the mb car like i would a hire car as i do not own it and lease it.
I don’t really care if it goes back with the engine smashed, but as of yet not one has, but i don’t race the engine until the oil has warmed up fully and one deffo needs to be careful until the brakes fully bed in.
