Hi, here’s a little guide to get your control unit up to date after changes. 1. Terminal minus pole from the battery, about 5-10 minutes. Then connect again. 2. Ignition key to the ignition lock and ignition on, but don’t start. Who wants to hear how the throttle flap and actuators adjust, can go back to the open hood. It’s very good to hear. Important to wait 5 minutes. 3. Start the car, but give it no gas!!!!!! That’s very important, otherwise the 4. The entire learning process takes about 50 km of driving distance. During this time, you should play through all driving processes. Turn out times to maximum speed, sometimes go underboard. 5. With every change you make on the engine (K&N filter, sports exhaust, N75, pop-off, chip etc.) you should repeat the process. 6. Do not forget to unlock the radio (see operating instructions ) 7. Have fun !!! Greeting Grey
