I think I may need to replace the DME. What are the the things I need to do or know to accomplish this task?

 

Relatively simple. Just ensure that your ignition has been off for at least 5 minutes because it can retain a charge that might cause damage when removing.

 

So what all do I need, and need to do to have a successful swap?

 

swapping the DME is not an easy task if you don't have the right tools. I am not talking about physical removal. in short, you're looking to "clone" you DME. you need a donor DME with same part number and Ktag to read and write the ECU file. what year an model is your mini?

 

its an 09 Cooper S.

 

this has the TC1766 infoen ic chip. Ktag can read it on the bench (the back cover of the ecu needs to be removed and then connected to the tool to read the file and then write it on a good donor). PM https://www.northamericanmotoring.co...ototype-r.html and let him know I referred you to him. let him know you want to clone your ECU.

 

I know on at least some Porsches you have to replace the DME, Immobilizer, and Key pill as a set and it works fine. Is that not the case with the Mini?

 

It is. BUT, these sets can be expensive, the car looses its identity in terms of true VIN, may loose the true mileage, will have a tampering protection dot on the speedo, if you loose the key, the dealer won't replace it for you since the donor set is not from the acutal car....the list goes on and on. At the end of the day, it's your choice

 

Hummm... I wonder if the original DME can be fixed, assuming its the problem?

 

Not knowing which circuit controls the fuel injectors or spark plugs makes it more complicated. Also sourcing the components can be challenging since unlike thru whole soldering, the surface mount components don't show values.



this is from a 2007 N12 ECU I have. The easiest way is to clone it. You can definitely look for any obvious burns on the board.

 

He said he doesnt clone DMEs.

 

Hummm...i though he would since he has the tool. At any rate, you could get Ktag and do it. I haven't been successful sourcing a good working unit lol

 

i don't even know what a ktag is? what does it cost?

 

Ktag isKtn ecu/dme reader/writer generally used for tuning. The idea is to read your file and then write it on a donor ecu with the same part number.

 

Touch base with "adriancl" on this forum. He can recreate your ECU using your VIN and tune it as well.

 

Sounds like something better left to an expert.

 

Thanks, I'll look into that.
