Mercedes C43 ECU Tuning

Custom tuning will be for cars equipped with any MED17 ECU. To find out if your car has a MED17 ECU, you must pop the hood and look around your engine bay. Google your year make a model and type "ECU location" at the end to see where your specific ECU is mounted. On most cars, it will be right on top of the engine, on the side of the engine, or on top of the airbox. Once you have found the ecu on one of the sides you will see a tag or label with the words MED17 with more numbers following it for example MED17.7.3.1 for C43, MED17.7.5 for C63, or MED17.7.2 for A45.

Rev Limits, Vehicle Speed Limits, HP & TQ Gauges and more are all found in the CPC (Central Powertrain Controler) and are not included with the ECU Tune. 

Most cars can be tuned without a CPC tune
