With an absolute accuracy of 0.299% or better, the most accurate jetting software money can buy!

 

 

The Dellorto JET-TECH PRO screen gives the Main Jet, Needle Clip position and Spark Plug for any Carburettor from the Dellorto range. All needle designs available from Dellorto (suitable for Rotax Max –Micro / Mini / JNR / Senior / DD2, 125 ICC, RoK, Biland and many others) are accommodated.

JET-TECH Pro will calculate accurate main jet selections for the jets 30 to 330 and precise needle clip positions for the needle series: A, AK, D, E, M, K, U, W, X suitable for the Dellorto carburettor models VHSA, VHSH, PHBE, PHF, PHM, PHSB, PHBH/L, PHBG, PHVB, PHVA, PHBN, SHA, SS1, UB, VHB and of course, the VHSB for the Rotax Max. Jet-Tech Pro covers all Dellorto venturi from 7mm to 42mm.

 

   

The accuracy of the Pressure, Temperature and Humidity data you enter into your application has a direct bearing on the accuracy of the end result!

JET-TECH provides you with a unique copyright feature that will calibrate your barometer to an absolute accuracy of 0.299% or better. This process provides the perfect Software/Barometer calibration. Use the Jet-Tech Weather Pro weather station and you can take advantage of a weather station that is 10 x more accurate than other comparable units! JET-TECH Pro remains the most accurate Jetting Software money can buy.

 

   

JET-TECH Pro continually monitors the Dew Point Temperature and displays a Carb Ice warning when atmospheric conditions are such that Carburettor Ice may form.

This feature is an essential aid for Professional or Amateur carburettor tuner alike. It adds another dimension to understanding fully the performance envelope of the Dellorto range of carburettors.

 

   

'Unlocking' from the main Dellorto screen, reveals all of the variables and adjustments for the Dellorto single-choke carburettors. The user can select from the full range of needles, the venturi size, needle jet, idle jet, float weights, float height, all from drop down lists. In addition, spark plug manufacturer - NGK or Denso - can be selected at the click of a button.

   

The user can modify the settings to allow for the different characteristics of each needle, relative to their specific engine/carb combination. Needle Selection can be made from a drop-down list of all needles manufactured by Dellorto for their single-choke carburettors. Any needle design such as the K98 for MAX, the K28 for the RoK, the U2 for ICC and/or the full range available to other classes, is easily accommodated with this facility.

   

All Dellorto float weights are included and easily selected. Float height can be set in 1mm increments allowing the user to map tuning changes to the floats. Changing the float height affects jetting across the throttle range. This feature enables you to reflect those changes and helps you to keep track of your different carburettor setups.

   

Mid range performance, 1/4 to 3/4 throttle opening, is actually controlled not only by the needle type selection but also the needlejet size and type selection. So when class rules allow, another feature exclusive to Jet-Tech Pro can be used. This feature changes the recommended needlejet size as the air density changes so perfectly matching the changing conditions. This feature can be 'fixed' for classes where a specific needlejet must be used - such as in Rotax MAX.  The full range of Dellorto needlejets can be easily selected.

   
 

 

Jet-Tech Flow-Bench © is a unique and Copyright feature of all Jet-Tech software and is designed to enable the user to perfectly match Carburettor, Engine, Exhaust and Jet-Tech Software for all racing conditions and states of engine tune.

 

Because the Dellorto range of carburettors are a mass produced item, no two will Flow air and fuel exactly the same and whilst Jet-Tech Pro will, for 99.9% of carburettors, mirror the performance exactly, it may be that your engine tuner/builder has optimised your engine and/or exhaust pipe in a particular way that requires a different jetting and needle curves to get the maximum power and torque out of your carb and engine combination.

 

If this is the case and/or you want to experiment with your carbs set-up and performance across all air density ranges, then the latest Copyright features of Jet-Tech ‘Flow Bench’ are what you have been waiting for.

 

You can now set-up even more accurately how Jet-Tech Pro operates and the jetting answers it gives you for all Air Density values (Temperature, Humidity and Pressure), and adjust the rate of change of main jet and needle clip settings required, relative to changes in Air Density - bearing in mind of course, that for 99.9% of users, it will already be operating exactly how you want it to without any further adjustments being made.

 

Jet-Tech Flow Bench together with all the other unique features of the Jet-Tech Software range give you the opportunity to increase your understanding of carburetion and the effects of different carburettor setups on your engine's performance, thus enabling you to maximise the full potential of your engine/exhaust/carb combination. 

 

Up to 10 different configurations/settings can be saved in the Set-up database. So when you change your carb type, carb settings or engine, you can easily recall your optimum set-up for the chosen combination thus maintaining maximum performance with the click of a button.

   

The Dellorto Needle Analysis Screen allows the user to compare the characteristics of a selection of needles from the complete Dellorto range. Using one of the needles as a reference, the user can compare the flow characteristics and equivalent jet settings of other needles for a given throttle opening ie. to see if needle 'X' is leaner or richer than needle 'Y' for any given throttle opening etc.

   

The Diaphragm Carburettor screen is used to calculate the Jet settings of any 2 or 3 jet carb used when racing FA, ICA, 100 National, TKM, Cadet, TaG and many other formulae. Using the accurate weather data, Jet-Tech will display the recommended settings for each jet. In addition to jetting, Jet-Tech will also provide plug type/heat range information.

You can also setup your carbs pop-off pressures and then the software will calculate and display your new pop-off pressures (in PSI or Bar) as the weather conditions change. In this way you can exactly match your unique carburettors characteristics and maintain perfect jetting each and every time to go to the track.

 

   

Jet-Tech Flow-Bench © is also provided for 2 and 3 jet fixed jet diaphragm carburettors.

 

Many engine/carb tuners provide optimised settings for their fixed jet carbs. Not only can you match your tuner's specifications but you can now fine tune them across the whole Air Density range.

 

   

 

 

Jet-Tech Air Lab gives you an insight into just some of the internal calculations used by the Jet-Tech Dynamic Simulation Model© to precisely maintain optimum jetting for all versions of Jet-Tech software.

Jet-Tech Air-Lab has been developed to bridge the gap between the old, traditional approach to engine tuning which in the past was based on tuning indicators such as Density Altitude and, often inaccurate, Relative Air Density (RAD) Gauges and the modern computer based approach which fully utilises powerful advanced carburettor simulation software such as Jet-Tech PRO.

Air-Lab will calculate the atmospheric data collected from the weather data entered on either the Dellorto or Diaphragm carburettor jetting screens within Jet-Tech PRO.

Jet-Tech Air-Lab calculates and presents data that can be used to calculate the Dyno Correction Factor and Relative Horsepower when testing engines to internationally accepted standards.

   
   

The Gear/Oil/Weight screen, calculates Gear Ratios, Equivalent Gearing, the Gearing required to pull target revs for both fixed drive aned gearbox Karts. Kart Chassis Weight and Balance - essential to check for chassis twist or incorrect weight distribution can be recorded. Also Kart Speed at maximum revs in KPH & Metres per second and finally Oil/fuel ratios can be calculated.

   

The Kart Handling Analysis screen enables the user to enter general chassis handling characteristics at entry, apex and exit of corners. Characteristics can be selected for each point, from a drop-down list and corrective action is suggested. Detailed notes can be accessed at the click of a button and your own observations and settings can be added.

Tyres are designed to give optimum grip at the optimum carcass temperature. Jet-Tech Pro now gives you a facility to record your tyre temperatures. Knowing these temperatures is an extremely important factor in finalizing the settings for your Kart. Jet-Tech can supply you with a quality, combined tyre pyrometer and electrical multi-meter - the Jet-Tech Race Meter - to take full advantage of this unique feature of Jet-Tech Pro. 

With the Jet-Tech Race-Meter, T-Spy and other suitable tyre temperature probe (not provided with the software), temperature readings are taken from the inside middle and outside of each tyre, and entered as shown. The software records these and provides an average temperature for each tyre.

With the direction of the circuit (clockwise or anti-clockwise) selected. Jet-Tech Pro will then generate a detailed report containing information such as inflation pressures, castor, camber and weight distribution characteristics, rear axle, hub, wheel performance and finally, geometry checks. The report can be saved to your notes for review and/or further analysis.

   

The Kart Set-up Data screen is used to record your Kart Setup,  engine choice, gearing, tyre and track temperatures and laptimes for each track session using the drop down menus. Jet-Tech can also accommodate up to 10 different engines, recording your serial numbers and engine running time. Data saved is relative to the engine used in the session. Tracks can be entered and saved for easy retrieval of data later on. Saved data is kept in the Jet-Tech Data Analyst database and/or can be saved directly into your data logger software or into the notes feature of this software, or any other Windows software running on your computer such as Microsoft Word, WordPad etc.

   

 

Jet-Tech Data Analyst is the latest copyright feature of Jet-Tech PRO. It brings the power of a fully searchable setup database to the worlds most popular Kart jetting and setup application.

All your Kart setups can be saved to their own individual records and can be sorted in any order - such as quickest laptime, wet or slick tyres, date, engine number etc etc..

 

   

The user can select a track and all the records for it will be displayed in the list at the top of the screen. This list can then be sorted into any order - such as quickest lap and the kart setup information is then displayed for the chosen record.

 

Free-text notes can be added to any record and detail changes to the setup changed if required. The user can search all records on any variable. So if you wanted to find your best chassis setup, for a particular circuit on slick tyres, using a hard axle and a soft seat, Jet-Tech Data Analyst will find it for you!

Chassis setups can be loaded directly into the setup screen, from which you can produce a detailed setup sheet. This can be printed out and used to guide you through your chassis configuration when you're in the garage or awning.

Each Jet-Tech screen is complemented by helpful notes to guide you in using Jet-Tech to get the best from your chassis and engine. This feature also allows you to record any data and records you require for later analysis and review.

 

 

JET-TECH PRO comes with fully searchable, context sensitive help files. The help files for each screen are easily reached by pressing F1 on your computer keyboard or clicking on the ? in the bottom left of the screen.
