Just Performance. Not Heat.

Even when used at the highest horsepower level, typical exhaust gas temperatures are on average 200°F cooler than with stock software. That is true optimization.

Smarty Jr J-06 is loaded with its homebred bootloader to allow convenient and faster flashing up to three times faster than Star-Scan diagnostic tool or any other competitor. Pulling fuses after an interruption during updates are things of the past. Just turn the key OFF and ON and Smarty does everything else on its own.
