W205 C63 C63S AMG ECU Tuning Thread
It uses 5 sensors (same 4 sensors as Dinan, but with an additional 5th sensor for camshaft/timing).

Dinan or racechip seem like a good option for tune only.
I tried working with RaceChip (GTS Black) several times before ultimately deciding to go with Dinan. RaceChip sent me not one but TWO boxes that had the incorrect programming for the C63S (also, the bluetooth modules in both of their units failed out of the box). All the marketing in the world can't convince me that its worth going with a vendor that doesn't even bother checking or testing what software is in the box before they ship it out to be installed on a customers $90k AMG. It was a complete waste of time and a major hassle having to ship back and forth to Germany. I will give them credit in that they gave me a complete refund, including the cost to ship the box back to Germany twice. But their response was that it surely couldn't be their fault, and that I must have installed it incorrectly because they have "so many happy AMG customers". Well, Dinan installs the same way (and actually uses one less sensor than RaceChip) and what do you know - Dinan worked flawlessly.
Don't even consider RaceChip for this platform, spend your money wisely.

Good stuff man, your posts are really helpful. I was looking at RaceChip vs Dinan but going to stay away for now. I'm still split between doing a bench flash tune vs piggy back. I want to run catless downpipes for sure, but I guess I have some time to decide, the car at stock power levels is plenty.... for now.
I just tell the service adviser not to touch the ecu as I'm happy how the car is running.
