Ignition Configuration and Testing
02.07
| 00:00 | As with the fuel system, the correct configuration for the ignition system is going to depend on your engine. |
| 00:07 | Options include direct spark, waste spark, and distributor. |
| 00:11 | If we go to the ignition main menu, we first have the ignition mode which defines the type of ignition system. |
| 00:19 | In our case, the Toyota 3SGE uses a direct spark coil on plug ignition system. |
| 00:25 | Next we have the spark edge which defines if the ignition output is a falling edge trigger, or a rising edge trigger. |
| 00:33 | Most ignition systems use a falling edge trigger, but there are exceptions including Honda, Ford, and some MSD systems. |
| 00:42 | Getting this wrong can damage your coils, so if you're unsure, check with your ECU manufacturer. |
| 00:49 | Each ECU is different, but these two parameters are the most critical in setting up your ignition system. |
| 00:55 | There are some additional settings you can see here which we don't need to adjust in most installations. |
| 01:02 | We're now going to use the test mode to test the ignition system in the same way that we tested the fuel injectors. |
| 01:09 | This can be done by selecting ignition test, and then choosing each coil individually and confirming the coil is producing spark. |
| 01:18 | You can do this physically by removing the coil and connecting it to a spark plug that is earthed to the engine block. |
| 01:25 | You can usually do this test though without removing the coils as they'll make a slight ticking noise with each spark. |
| 01:31 | Again, we can confirm the coils are wired correctly by unplugging them. |
| 01:36 | If your engine has a distributor rather than a coil pack, you won't be able to test the ignition system properly without the engine running. |
| 01:45 | You can connect the coil lead to a spark plug though, and prove that it is generating spark. |
| 01:51 | By the end of this module, you should be able to configure your ECU to suit a particular engine, setup and test the inputs and outputs, and setup and test the injector and ignition outputs. |
