this is the old version ( dos) its old school but works well!i purchased it new from accel in 1999. i ran it for years with no problems. it has the three stage nitrous option and works with the opti spark. also comes with the dan white plug and play harness for 93 cars and the tuning cable and software. i may be able to throw in a older windows laptop to run it for a few extra $. asking $350 without laptop
