PRICE LOWERED!!! AGAIN!! ONLY ASKING $350! I am selling a Unichip piggy-back ECU system. I had this installed in my 2002 Cooper S for about 3 months. I sold my mini a few weeks ago so I no longer have a use for this. The Unichip is in perfect working and cosmetic condition from the time I installed it in my car to the time I took it out. While I had it installed I saw a great increase in power and low end torque. This worked seamlessly with the car's ECU and is great if you are looking for custom tuning. I enjoyed the choice of 2 different power maps depending on my fuel choice and driving style. Switching between power maps are literally as easy as flipping a switch. I am including everything that came from Unichip: -The Unichip ECU -Wiring adapter to connect factory ECU and Unichip ECU -Wiring with external switch to switch between maps -Original box and all original documentation -Step by step installation instructions -Optional USB cable to upload custom maps from your computer to the Unichip ECU On the Unichip ECU there is currently a map for a Mini Cooper S with 15% reduction pulley, CAI, and a cat-back exhaust. The great thing about this coming with the USB cable is Unichip gives you free access to their map database so you can literally upload the map that suits the modifications to your car in the comfort of your own home. PRICE LOWERED!! I am asking $350. I am looking to have this item sold ASAP so PM me with any offers around the lowered price! Feel free to PM me for more details. Paypal payment accepted and shipping at buyers expense.
