I am looking to getting into tuning on my 2014 ML350 Bluetec. What is the best system to use? WinOLS, Kess, or Dimsport. As I start to figure out things what will be the best one to stick with?

youre mixing things
kess is a tool gor read and write winols its a software for editing files
use kess for read and write the file and winols for modified it :thumbup:

Then what about Dimsport vs WinOls. It's so hard to figure out how to bridge the gap when I know no one who does stock ECU's

DimSport is a reader and WinOLS is an editor... not the same thing..

wbr

So you can't edit with Dimsport? It looked like you could but please correct me if I am wrong before I spend the 5k

Go to pro tuner and pay for remap. With your knowledge, your Merc is in danger.
Faults are expensive to fix.

Not everyone is born with the knowledge. I am trying to learn.

My Merc ECU was sent to a pro tuner and he did his best but with the bigger turbo I have fitted I would like to do better.

Buy 1.9 tdi with edc15 for learning :thumbup:
