Improve transmission performance in your smart with the MADNESS Autoflash!
This little device will remap your TCU to improve shift times, bypass limitations, and change shift points for an overall better experience!
Best of all, the dealers will never know you have it installed!
It will not trigger a flash counter that would alert a dealer to software changes.
We have versions for the 450, 451, 453, Roadster, and Crossblade!
