Mercedes attempting to cut down on M156/E63 AMG tuning by changing ECU coding?
Well, that is the claim of Singh Autosport but not exactly the most credible source. Regardless, this warrants further investigation. Singh claims that the ECU files have undergone a change in 2011 and the file is now twice the size it was previously and quite different. So is Mercedes trying to slow down the tuning of the M156 and E63 AMG? Does this mean Mercedes is going to be proactive in trying to curtail tuning? Certainly looks that way. Let's see what our own tuners have to say about it.
