    I just got my Ferrari 488 GTB few days ago and I tried to drive on daily basis as my dealer told me that battery may goes flat if I park my car without connect charger.
    This morning when I try to start engine the warning code came up indicated engine system control failure, after tried few times of engine start and off few times the warning still doesn’t go off.
    I called the technician who told me the battery will only charge if I push engine speed over 3,000 RPM, is that true? He told me battery will not charge if I choose Auto gear wet mode as gear shift always like 2,000 RPM. Can anyone help?

    Not true. It will charge from idle. It is true wet mode shifts early (2000) but it will charge.
    His statement may come from early cars that will have the alternator light on until it sees about 2500-3000 RPM, the light will go out and it is charging, but even after that it is charging at idle.
    You may need a battery reset. That shuts everything down and then allows all of the ECUs to restart. This may do but it may not, just a first step.

    Disconnection and reconnection of the battery.

    Disconnection and reconnection of battery 12V was always resetting the learned block memory in the motronic ECU. Term battery reset was ECU reset since the 348 days. In the 348 we only had symptoms of the issue now the dash says "engine system control failure" I guess? It is amazing after all these generations motronics still have this legacy problem that other ECU manufacturers have figured out.

    I guess one also loses the radio settings?

    BTW- I hate glowing red alternator charging lights, even if the alternator is really charging. Some day, it might be a real alarm.

    Another Ferrari inability to deal with modern electronics. Ferrari is always 10 years behind everyone else in managing their electrical systems while using modern electronics. We see the problem in their lack of reliability and quirky issues like battery/ECU reset or smog readiness as examples. We even see those issues vary among specific cars!

    Why won't you just get battery tender? Would make life that much easier :)

    As a long term Ferrari buff (had a Dino when they were new) I've never understood the electrical malaise. I just started up my GT3 Porsche after 3 months (no charger). Started right up!
