Banks Bullet Diesel Tuner - For Sale

Sorry all if this is the wrong area but couldn't find a classified section to the site. Traded in my 2015 Eco this past summer and just remembered I had pulled this tuner out of it years ago. Seems like it's not available anymore so may not be worth anything. Anyone interested? What's it worth? Thanks! I do miss my Jeep every day but with 177k miles and needing a vehicle more for just commuting now it was time for her to go.
