Trying to DIY ECU Programing & Coding
I recently purchased a 2016 E250 BlueTec, absolutely love the car. But i am not a big fan of the AdBlue (DEF) system. I am well aware that deleting it can get me better mileage, better engine life, more emission 🤫 , and no warranty. However the performance gain and economy does it for me. My friend purchased an ML350 BlueTec and got his system deleted for 1000$. Im looking into the DIY option for doing it cheaper and learning a thing or two.
I am currently waiting on my Multiplexer, and will have Xentry, Monaco, and Vediamo installed. I was under the impression I could do it with those but I was told that deleting the AdBlue requires the ECU to be reprogrammed/coded. If that is the case can someone elaborate and explain?

Adblue delete needs to be done by tuning. You will need to read the flash file from your ECU and then modify the file to delete adblue. Write it back to your ECU and done. Not possible with Monaco, Xentry or Vediamo.
