FAQ

Mercury tuning FAQ

Does the GAN module affect my Mercury factory warranty?

Your manufacturer’s warranty is preserved: the ECU software is never changed, and the module can be removed at any time.

Plug-in performance chip or flash tuner: which should I choose?

A flash tuner rewrites the maps in your ECU, and the flash counter records it. The GAN module adjusts the sensor signals instead: the ECU stays in factory condition, and you can return the car to stock in about a minute.
