Can you hack into your car's system to customize features not available through traditional means?

Have you ever considered using MES to access hidden menus or modify settings in your vehicle that are not typically accessible to the average user? What are the potential risks and benefits of hacking into your car's system for customization purposes?

MES can only do what it is programmed to do. The is no command line functions for non MES supported functions/ability. The only thing one can do to change things not in the main control unit menus and "Adjustments" tab is to do a Custom Proxi Alignment.
CAUTION: Custom Proxi Alignment has the potential to "brick"/break/kill your car. There are up to 255 bytes and each byte can have 255 values, so potentially 65,0000 values to change things.
Before you ask Proxi byte information and what each bytes and value does is Fiat/FCA confidential and restricted information. Nobody has ever found a definitive document or information that details Proxi data.
Proxi byte changes here on MES Forum (and elsewhere) have been worked out by users doing very careful unit changes etc. and mapping values.
