How to mount an additional control unit to the Ford Focus MK4

Let's see how to mount an additional control unit to the Ford Focus MK4: ADDITIONAL because in this way we do not risk invalidating the warranty. We will have both a nice boost at low revs, and we will add about 30 horsepower. This is the GT2 of Powerking (you can find it on powerking. It) and can be controlled by bluetooth. We can control the acceleration, the turn response and that of the commo-rail. Let's see the assembly. We open the oil cap to remove the engine cover, and put it back right away. Under the coolant reservoir of the intercooler, we find the first sensor: it controls the turbine. The other is located under the rubber protection of the engine: it concerns the pressure of the common-rail. In the video, the youtuber indicates where to pass the last connection, the one for the accelerator pedal. Entering the car we then see the exit to attack the accelerator. Our enthusiast guides us step-by-step in each step, after showing us the various connections, in all the operations. We position the control unit so that it does not bother closing the tailgate and we pass the wire inside the car. We connect the wire coming from the additional control unit to the accelerator. Now let's see if there are any errors on the application. Let's go to FordScan; we see from the parameters that there is no error. We open the powerking GT2 application, which we will have installed in the meantime: we have to set our parameters: if we leave it on green we will have the parameters of the house, if we put it on blue we can set it to our liking. If we go to learning there are all the instructions to make our car learn the parameters we have set. We just have to do a road test.
