This is a single cable needed when using MEMS for a Rover Mini. The length is approximately 1m. I purchased it on Mercari last year. I will also include a Windows version of free software on an SD card. It's convenient for checking the MAP, etc. I have confirmed that it works without any problems on my own Mini to verify its operation. I am selling it because I have sold my Mini. No claims, no returns, and no cancellations are accepted. This is specialized equipment, and I am not very knowledgeable about it, so I basically ask that only those who know how to use it purchase it.
