Want to grab a 2nd ECU for my '12 E63 pre facelift biturbo car 😁

 

 

Call your dealer and get the ecu number..or take the ecu out and look on the back side of it for the number...once u have it type iy into ebay search...find the right ecu and get it.
I have a 2nd ecu with a race gas tune...
all you are going to need is send the original ecu with the new one so they can clone the original one onto the 2nd ecu and thats it..u can keep your original stock and do the 2nd one with a tune or whatever u like.
I'd recomend Eurocharged they are the best hands down..

 

PM me the info off your ECU I will try to source you a used one.

 

Post or PM me your VIN, and I'll get you the current part number of MB Site.

 

i've not looked into this much, but a quick check on EPC shows these part numbers for a engine control unit when using my VIN (15 E63S). when i check those on eBay there are several that show for sale around 800-1200 USD
