N14 SWAP N18 ( EP6FDTR 308 GTI 270cv)

Hello everyone, I come to present my project, I own a mini JCW N14 of 2009 with dead engine.
I swapped with an N18 engine (EP6FDTR) from a 2016 308 GTI 270hp.
I keep the manual gearbox of mini N14 with DKM clutch kit.
I have the 308 GTI harness
I also have the ECU of 308 GTI bosch MEVD17.4.4 on which I will do an immo off
I own all the electrical diagrams of 308.

I am looking for the electrical diagram for mini N14 as well as the electrical diagram for mini N18, in order to be able to compare them and to be able to adjust my beam for the ECU connection.
Could one of you provide them to me or tell me how to do them please?

if the adaptation does not work with the ECU of 308 GTI, I would do it with an ECU N18 after April-2012 (Bosch HP pump)
Do you have an EMR reference recommended to me?

Is it possible to use an EMR from an automatic transmission? or do I absolutely need a manual transmission EMR?

I have all the necessary equipment to do reprogramming
Autotuner
kess V2
Ktag
Maxisys MS919 altar

I would love to benefit from your experience and you propose mine.
I use a translator, excused mistakes or spelling mistakes.

We dont have the 308 GTI 270hp here so unless someone did that overseas, not going to have much info. Most just swap in a used N14 or N18 stock to stock or have a built performance engine. We just had a local guy pick up a N14 JCW engine that is going to be beefed up a bit.

The TIS used to have the diagrams but you have to pay now. https://bmwtechinfo.bmwgroup.com/#/login

Hope that helps.

Ok welcome!

We carry a bunch of the parts in aftermarket that fit that engine that is shared. You will have to search under the Genuine MINI part.

Electrical Drawings for all Automotive Electric

I found a reasonable site to get any prints for wiring your car. I am in the process of doing a 2008 n14 to 2011 n18 swap.
It would be a bear of a job without a good set of color prints. Go to Automotive Electricians Portal. the company is out of Dubai but your prints are going to be around 20 bucks a pop but once you purchased the print you will be able to log in and view the links you have purchased in your own folder or download as pdf. Worth every penny
