We had another Mini Cooper S come in for a ECU upgrade on its 1.6L turbocharged engine. These are pretty easy to do and are done via the OBDII port. I personally tested one of these ECU flashes on my own 2013 Countryman S and it was a rocket! Read out the car, wait for the file, write the new file back, done and you are whipping up on the JCW edition. Our customer Nik was very happy and wrote us this review, “Genuine and quality customer service. All questions answered and alternatives suggested.” Check out all the VR Tuned Mini Cooper ECU Tuning here. Leave a Reply Cancel ReplyYou must be logged in to post a comment.
