You are bidding on a Racepak PROTUNE 400 dashboard with tons of extras! This dashboard will monitor exhaust gas temps and record your highest egt's on individual cylinders, it will monitor and record engine rpms, water temp, jackshaft rpms (with optional sensor not included). It will record all of these functions, play them back, and it will display them numerically or in graph form. This guage comes with 2 complete sets of triple exhaust temp probes, 2 complete water temp sensors, and 2 complete power hook up cables. It also comes complete with the 37 page PDF file with all installation and user instructions. THIS GUAGE PACKAGE WITHOUT THE EXTRAS COST OVER $1000 new! I am listing this at less than half that price! This guage worked perfect on the sled it was taken off of less than two years ago. The only reason it is not being used anymore is because the new MSD ignition on the sled is laptop adjusted and monitored. You can google Racepak Protune 400 and take a look at the 37 page instruction manual if you'd like to. Please take a look in my Ebay store for more snowmobile, atv, and watercraft parts and accessories.
