I have been looking into purchasing a 2nd ECU in order to not worry about my warranty with a tune. Has anyone on here done this and what is the cost for a new ecu. TIA

I talked to a tuner about this and said it could be done, but no Idea on the cost for the 2nd ECU. I read someone with an AMG GTS did this, maybe try searching him out?

hmmm thats not a bad idea, they are still difficult to get to though

why wouldn't you just re flash the ecu back to stock

For some people, that can be a real pain in the a**.

i.e. shipping the ECU overseas... Lots of down time, etc.

Having an extra ECU, if reasonably priced... Which is yet to be determined if it's even possible yet, would certainly be a convenient solution for those who want to avoid any warranty issues that an aftermarket tune can present.

It is possible, but there is a problem with that. You have to get the ECU from the dealer and the have to program the keys to the car before anyone can touch it. That being said, a dealer would thoroughly question why you are purchasing a new ECU for your brand new vehicle lol. It is easier to just program the stock one. I do believe for the 63/63s the ECU can be relocated making future programming much more simple than the initial removal

lol, if the dealer is gonna question why you're looking to purchase a new ECU for your new vehicle... Doesn't it stand to reason that they'd be just as suspicious, if not more suspicious, as to why you relocated the ECU?

Btw, does anyone know the cost of a replacement ECU?

A new ECU is going to be in the multiple thousands of dollars.

Yes I suppose that is valid haha I just know from a modifying end that the C63 ECU is nowhere near as simple to remove as the C43 and I believe an ECU for my car was around $1800.

got it. Thanks for the info.

Don't waste your money and time. The car has other can bus memory that will record your driving and vitals. If Benz Was to do a diagnostic they will find out about tune and ECU.

But, they will have to prove that tune alone caused failure in USA.

Can you share where you got this info from? What module(s) other than the ECU is logging engine parameters?

Here's an ECU for sale if you want a spare: http://m.ebay.com/itm/132176373236

As a C63 (non S) owner I'm curious as to whether the C63S ECU would be plug and play and give the extra HP and torque? Does the ECU also control whether Race mode is displayed or is that controlled by something different.
