Triggering Mode

| 00:00 | Now that we've talked about the various types of trigger input, we want to see how to actually set this in the ECU. |
| 00:06 | As I mentioned, most ECUs provide pre-set trigger modes to suit a range of popular engines, which makes our job easy as there isn't so much to adjust. |
| 00:16 | If we go to the trigger set up menu, we get a menu dedicated to setting up the trigger inputs. |
| 00:22 | The main parameter here is trigger mode. |
| 00:24 | And if we click on this, we can see all of the available trigger modes. |
| 00:29 | These are designed to suit specific types of factory engine. |
| 00:33 | We're going to leave the trigger mode set to Toyota 3SGE v VTi, which will configure both trigger inputs to suit our application. |
| 00:44 | Once we have configured the trigger set up, we can test it at cranking speed to make sure the ECU is seeing both trigger inputs and there are no errors being recorded. |
| 00:54 | We can do this by disabling the fuel pump and cranking the engine. |
| 00:59 | If we press F12, we can get the run times value screen and then we can click on the triggers limits tab where we can see the status of the two trigger inputs. |
| 01:10 | If this is OK, we also want to check the RPM being displayed on the laptop. |
| 01:16 | This should be a sensible value of around 100 to 300 RPM and it shouldn't be changing erratically. |
| 01:24 | So, by the end of this module you should know what sort of trigger system your engine has, how to configure the ECU to suit this trigger system, and test the ECU is receiving the correct signals. |
