Spare ECU for tune?
Have any of u purchased a 2nd ecu for a tune ( for warranty purposes)? I am told the dealer can tell how many times u flashed the ecu but if u r able to swap in an ecu that has never been tuned......what r ur thoughts?

That is not true. If the dealer or MBusa suspects your car is tuned, they can read your ECU parameters with or without α second ECU and know it has been altered such as your boost.
Here α tread on the W212 E63 that was discussed in length:

yes, I have 3 ecu's and I know it works for the w212, but I know that all data can be retrieved if any big warranty claim. The purpose of my ecus now is to plug and play between stock (for diagnostics) and then ams 93 octane tune and Eurocharged e40 E85 tune.
i always knew that if there was a big issue with the engine I would be stuck with a potentially huge $20-40,000 bill to get the car running again. After accepting that, I moved forward with the tune. Truly you need to be able to afford a $170,000 car if you're tuning a new w213 and you may be on the hook for catastrophic repairs associated with the tune.

Get a tune from a reputable shop, find a shop that does not take pride in making the max power and in the process extracts every bit of juice out of the motor, drive the car sensibly and maintain it accordingly and you be fine. If you do break things in the process, then be ready for the repairs too.

if you abuse a stock tuned car it'll crap out on you faster than a tuned car that you take care of and don't abuse
