Hi all -

I’m not having any luck in finding someone to do the necessary ECU/TCU coding required if I were to change the final drive ratios on my ‘14 E550 4Matic from stock 2.47 to 3.07 (from the E350 same year).

I know I can physically make the swap, but I have no info on who can do ECU/TCU coding.

I already have a wicked E50/WMI tune from Slav @ ECC, Blackboost intakes - and now I want more torque multiplication!

Thanks!

Bill

Shoot me a PM. I can definitely get it done for you. Just Friday I did a 2013 C63 from 2.82 to 2.65.
