As cars have become more advanced, more and more operations of the car are controlled by the ECU, making the upgrading process increasingly complicated from an engineering standpoint. Nevertheless, upgrading an ECU is an affordable and relatively easy way to produce decent power gains. This is particularly true of a turbocharged car like our 854R where the ECU also controls the amount of boost and more recognizable gains can be had. With all this in mind, it’s important to not jump into choosing an upgrade lightly. While easily installed, a reprogrammed ECU or one with a chip installed can also cause a lot of headaches.
