I traded in my 2015 hardtop JCW for the new 2017 Countryman S all 4 for my wife and child's sake. Couldn't really afford the Countryman JCW so obviously way down in power ( was at 261 whp on the jcw). I had the NM module on my JCW and loved it. I have also read good things about Dinans, though if I read correctly somewhere, it makes less power at the wheels then the NM. Does anyone suggest a better option, or should I just order a new NM module for my Countryman since I left the old module on the Mini at the dealership so someone else can enjoy that extra power.


Thanks,
Jason

 

Nm FTW!

 

Probably Bytetronik tune instead of a piggy back. Although I did love my JB4 when I had it and you can get a Bytetronik back end flash to work with the JB4. Or just a normal tune from them.

 

Since it's a new car he might want to keep his warranty.

 

I wouldn't mind a tune over a piggy back, but it needs to be a tune I can install like I had from RMW on my 2010 S. Just use a personnel hand held controller with Jan's tune and 6 seconds later my car is tuned. It does me no good if the dealership reflashes my car for some reason and I loose the tune and now I'm either out the money, or have to down my car for an ECU and get a rental.

 

Dinan unit here and love it
