Eco Off™ for Mercedes-Benz SL Class ECO231

Mid City Engineering™ is now offering the only Eco Off™ solution available for your Mercedes Benz vehicle that does not alter the OEM wiring or software - ensuring all warranties remain intact.

The factory Eco feature defaults to the 'On' mode every time the vehicle is restarted- but not anymore. With our all new Eco Off™ interface, Eco is set to 'off'* upon vehicle start up, providing you complete control!

*Eco mode is not disabled and can still be used when desired.
