Thanks to its compact design, our tuning box can be fitted directly under the engine cover of your 209/309/509 CDI with 88 hp. This reduces the installation effort and provides effective protection from prying eyes.

Most competitor products rely on a separation of device and wiring harness. On the one hand, this creates the problem that it is difficult to find a suitable mounting position for these devices. On the other hand, when the hood is opened, the specialist immediately recognizes that the vehicle owner has tampered with the engine.

The micro chip tuner is so small that it can be mounted directly under the engine cover. Thanks to the simple installation, the device can be removed at will or is not visible in case of doubt.
