Trigger Mode
02.20
| 00:00 | Now that we've talked about the various types of trigger input, we want to see how to actually set this up in the ECU. |
| 00:07 | As I mentioned most ECUs provide preset trigger modes to suit a range of popular engines which makes our job easy as there isn't so much to adjust. |
| 00:17 | Since our M150 is preconfigured for the Toyota FA20 engine, we can't adjust the trigger mode. |
| 00:23 | Let's have a look though at how we'd do this in Motec's 100 Series ECU Manager. |
| 00:29 | If we go to the sensor setup menu and select ref sync sensor setup, we get a menu dedicated to setting up the trigger inputs. |
| 00:38 | The main parameter here is the ref sync mode. |
| 00:41 | If we press F1 for help and cycle through to the OEM modes, you can see all the available trigger modes. |
| 00:48 | These are designed to suit specific types of factory engine. |
| 00:53 | We're going to configure the ECU to suit a Mitsubishi Evo 6 engine, and Motec provide a datasheet to help configure the inputs to suit. |
| 01:02 | This datasheet can be downloaded from Motec's website, but we can see the relevant information here. |
| 01:08 | When we're setting up the trigger mode, all we need to do is copy the information from the datasheet into the ref sync setup menu. |
| 01:17 | The CRIP function is Motec's way of telling the ECU where TDC on Number One cylinder occurs. |
| 01:23 | We're going to look at setting this function a little later, but the datasheet should get the trigger setup close enough that the engine will start and run. |
| 01:31 | Once we've configured the trigger setup, we can test it at cranking speed to make sure the ECU is seeing both trigger inputs and there are no errors being recorded. |
| 01:41 | We can do this by disabling the fuel pump and cranking the engine. |
| 01:46 | Most ECUs have a status display that will let us check that the ECU is receiving valid signals from the trigger inputs. |
| 01:52 | If this is okay, we also want to check the RPM being displayed on the laptop. |
| 01:58 | This should be a sensible value of around 100 to 300 RPM, and it shouldn't be changing erratically. |
