Fuel Pump Output
01.22
| 00:00 | - Let's start with the fuel pump control. |
| 00:02 | The G4+ cannot directly run the fuel pump so instead we us the ECU to control a relay. |
| 00:07 | For our example, the fuel pump relay is wired up to auxiliary output one. |
| 00:12 | If we press escape to access the ECU settings menu, and then type aux, we will see a list of the available auxiliary outputs. |
| 00:21 | Click on aux one and then double click on function. |
| 00:24 | A drop down menu opens up and we can select fuel pump. |
| 00:28 | It is worth noting that when initially configuring auxiliary outputs, we can select test on to force the output on and test the circuit. |
| 00:37 | Test PWM will provide a pulse width modulated output suitable for testing pulsed outputs such as boost solenoids or cam control solenoids. |
| 00:47 | Once we have selected fuel pump, a couple more options become visiable. |
| 00:51 | Firstly we have the polarity of the output. |
| 00:54 | This selects whether the output channel will go to ground when the output is on or off. |
| 01:00 | This depends how the circuit is wired and usually should be set to low. |
| 01:04 | We also have the prime time which defines how long the fuel pump will run for when the ECU is powered up. |
| 01:11 | This allows the fuel system to gain pressure before the engine is started. |
| 01:15 | The default is three seconds which is usually adequate. |
