I'm pretty sure you can order a replacement VCI 100 online. If you have a Co Worker with a Maxi Sys Elite , ask if it came with a VCI 100 besides the MaxiFlash Elite, and see if you can pair it to your tool to get by with for awhile to make sure you don't find yours later. I'm thinking it could be paired with multiple Autel Tools, unlike Strap On where it is likely married to only one specific tool for life and costs well over a $1000 if you ever lose the one for a Zuest , you'll be holding your ankles taking it greek style Bigtime, LOL. I see VCI 100 sold online from dealers in China for about $230. JB Tools in the USA sells for about $555.They probably figuring worse case scenario price of having to warranty it out and providing support to folk who are totally clueless. List is $649
