Road Tuning: ECU Configuration
ECU Configuration
01.46
00:00 | Most stand-alone ECUs are designed to run a wide range of engine configurations. |
00:05 | This means one of our first jobs is to tell the ECU what engine we want it to control. |
00:10 | In this example, the Link G4 Plus we are tuning comes preconfigured to run the Toyota 3SGE BEAMS engine we're using for our demonstration. |
00:20 | If we connect to the ECU and move to the configuration menu, we can see the main parameters that need to be set up. |
00:27 | This includes number of cylinders, engine type, and the firing order table. |
00:33 | This is critical on some ECUs as it will define the order in which the injectors and ignition drives are activated. |
00:41 | Along with this basic configuration, we'll also need to define the trigger input that the ECU will expect to see. |
00:48 | This lets the ECU decode the engine RPM and engine position. |
00:53 | Since this is one of the most critical aspects to configure, we'll deal with this in a separate module. |
01:00 | While we're doing this basic configuration, I also like to set a sensible engine RPM limit and a boost limit if we have a turbo or supercharged engine. |
01:10 | Let's jump back to the PCLink software and we can move to the RPM limit menu. |
01:15 | This allows us to configure the type of limit we want to use. |
01:19 | In this case, we'll select an ignition cut limiter. |
01:22 | Now we can move to the actual RPM limit table. |
01:26 | You can see we can set the RPM limit relative to engine temperature. |
01:33 | This lets us set a lower limit at excessive engine temperature to help protect the engine. |
01:37 | If you want to set a boost limit, this can be done in a similar way. |
