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. Two for Commander, three for X3, etc. |
|
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. Using the 2020 X3 RR as an example, the Fuel Pressure Deviation Correction Factor is 1.0 at 65.3 psi, which is the intended pressure. |
|
|
|
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 and paste 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, 11v, etc.) |
|
11. Copy and paste the Injector Scaling, Min IPW, and Fuel Pressure Deviation Correction Factor values from the Data Generator to the Dynojet C3 tuning software. |
|
12. Under Fuel, in the Individual Cylinder folder, set all cells in the Factor to Correct Fuel Delievery Cyl 1&2 tables to 1.0. |
