    Jet-Plus is software for calculating the correct jetting or fuel control setting for your race vehicle to suit the current ambient conditions. Jet-Plus comes configured ready to use for Rotax Max FR125 Go Kart engines for use in Sprint Kart racing. It is also suited to, and user configurable for almost any type of race vehicle.

    Jet-Plus is a simple user-friendly PC application designed for helping you, or your race data analyst, tune your race engine fuel system to get the best performance in the prevailing ambient conditions.

    When you have two different fuel set-ups that work very well, Jet-Plus provides the ability to calculate the fuel set-ups for all other conditions allowing you to spend more time getting the rest of your vehicle set-up right, knowing that the fuel mixture is going to be very close to ideal.

    Jet-Plus has been around for a few years, and Version 4 is now available. The major enhancements are a 60 day trial period with much simpler registration process, and the ability to print a graphic chart for the selected vehicle that can be used as a quick reference without the need for a computer at the race track.

    Jet-Plus V4 has retained all the features of earlier versions, and has updated help to cover the new features and all other help has been revised, all at the touch of the F1 key. Click here to see the on-line help (Click here to see the on-line help file for V4)
