1. Choose the Injector Model. |
|
2. Define the Engine Displacement with the slider control, or by entering the number directly into the value box below the slider. Do not use the advertised value – Use the value from the stock calibration. |
|
3. Choose the number of Cylinders. |
|
4. Define the method of Aspiration. |
|
5. Define the Pressure Reference. |
|
6. Define the Fuel Pressure. The allowable range is from 29 to 101.5 psi. Fuel Pressure varies among models and years. In most cases, you can find the stock Fuel Pressure in the repair manual, or from the calibration. To our knowledge, The XP1000, Turbo S, and XP Pro run 55.1 psi (3.8 bar). The Fuel Pressure Deviation Correction Factor is 1.0 at 55.1 psi, which is the intended pressure. Other models have not been validated. |

|
|
8. If using Gasoline/Ethanol blend, define the ethanol content of the fuel, from 0-98%. Note that your UTV was calibrated at the factory with Emissions Certification Fuel which contains 10% ethanol, as does most pump gas. |
|
9. For Custom Fuel, enter the Stoichiometric Air Fuel Ratio and Density. For Methanol or Gasoline/Ethanol blend, these values are not used. |
|
10. Copy the Injector Latency values from the Data Generator to the Dynojet C3 Tuning Software, and change the Injector Latency axis values to match that shown in the Data Generator. (8v, 10v, 12v, etc.) |
|
11. Copy the Injector Scaling, Min IPW, and Fuel Pressure Deviation Correction Factor values from the Data Generator to the Dynojet C3 Tuning Software. |
|
12. Enter the number of IPW Breakpoints from either the IPW Comp MAG or PTO table. The IPW Breakpoints are the X Axis or column values in the IPW Comp MAG & PTO tables. The default is 16, which applies to most calibrations. The allowable range is from 11 to 21. |
