Practical Standalone Tuning: ECU Configuration
ECU Configuration
02.08
00:00 | Most standalone ECUs are designed to run a wide range of engine configurations. |
00:04 | 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 M150 ECU we are tuning is specifically designed to run only they Toyota 86 engine, so these parameters we'd usually configure are locked. |
00:21 | To give you a better idea of how a conventional standalone ECU would need to be set up, we're going to have a look at the Motec ECU manager software for the 100 series ECUs. |
00:32 | If we open a file and go to the general setup menu, we can see there is a parameter for the number of cylinders. |
00:38 | Motec allow you to enter a positive number for 4-stroke piston engines, or negative numbers to indicate a rotary engine. |
00:45 | If we go back into the general setup menu, there is also an option which allows the firing order to be set. |
00:52 | This is critical on some ECUs as it will define the order in which the injectors and ignition drives are activated. |
01:00 | Along with this basic configuration, we'll also need to define the trigger input that the ECU will expect to see. |
01:07 | This lets the ECU decode the engine RPM and engine position. |
01:11 | Since this is one of the most critical aspects to configure, we'll deal with this in a separate module. |
01:17 | While we're doing this basic configuration, I also like to set a sensible RPM limit and a boost limit if we have a turbo or super-charged engine. |
01:27 | Let's jump back to the M150 software and we can move to the initial setup worksheet and then the engine speed limits page. |
01:35 | You can see here there are a number of RPM limits that can be configured for different states. |
01:40 | The main RPM limit, though, is called "engine speed limit maximum" and if we click on this, we can see it is set to 7,800 RPM. |
01:49 | The M150 has 2 adjustable RPM limits that can be selected using a driver switch. |
01:55 | These are the A and B settings we can see here. |
01:59 | We're going to leave the RPM limit set as it is and we can move on to the input setup and testing. |
