Selling my BMS stage 2. No gas station around me sells E85 and 93 plus I use this as a work car so I have to fill up fairly often and at two gas stations to take advantage of the thing.
I also have the stage 1 computer from when I upgraded for sale for $100. THIS IS ONLY THE BLACK BOX - THE COMPUTER. It does not include the wires needed to attach to the car. You can probably buy these from BMS. Maybe not. I don't know. Perfect for somebody who accidentally broke theirs.
This is for an N20 328i. Please don't ask me if it will work on your car, how to install it, etc...
