E Throttle
03.02
| 00:00 | - The G4+ ECUs also have the ability to control engines equipped with e-throttle. |
| 00:06 | If you have a G4+ Xtreme then you can purchase the code to unlock the onboard e-throttle feature or alternatively, you can use the external e-throttle module as you would with a G4+ Storm. |
| 00:18 | We're going to go through the setup procedure for e-throttle here. |
| 00:22 | For safety, e-throttle systems use a pair of sensors on both the throttle and foot pedal to ensure the signal output is reliable. |
| 00:31 | This requires analog inputs to be configured for a foot pedal main and foot pedal sub at the driver's pedal and throttle position main and throttle position sub at the throttle body. |
| 00:42 | Motor plus and motor minus auxiliary outputs also need to be configured to move the throttle plate. |
| 00:50 | If we head to the ECU settings menu and click on electronic throttle, we can start by selecting e-throttle setup. |
| 00:57 | The first step is to set the e-throttle mode to setup mode. |
| 01:01 | A warning will tell you that no safety systems will function and not to drive the car under any circumstances. |
| 01:08 | Press OK. |
| 01:10 | Next we can click on the TP calibration parameter. |
| 01:14 | Follow the on screen prompts and the ECU will automatically calibrate the throttle plate. |
| 01:20 | Once this is complete the box will confirm that the setup was successful. |
| 01:24 | Next click on the FP calibration parameter. |
| 01:28 | This will calibrate the foot pedal and you'll need to move the pedal through the range of travel before clicking OK. |
| 01:34 | Once these parameters are configured, you'll need to configure the frequency and deadband. |
| 01:38 | These are dependent on your throttle body. |
| 01:40 | Contact your local Link dealer for settings to suit your application. |
| 01:45 | There is also an adjustment for FP sub which can be used for some e-throttle systems where the FP sub input stops before the FP main parameter. |
| 01:54 | This is mostly found in Toyota and Lexus engines and needs to be set at the maximum level the sub parameter reaches. |
| 02:02 | The last setup we need to do is to adjust the PID settings. |
| 02:06 | We can get to these settings through the electronic throttle menu here. |
| 02:10 | Again these settings are dependent on your throttle body and your local Link dealer will be able to advise on the correct numbers to suit your application. |
| 02:18 | Once all the setup changes have been made, you need to go back to the e-throttle setup menu and change the e-throttle mode to on. |
| 02:25 | This reinstates the safety parameters. |
| 02:28 | Now your e-throttle body should be functioning correctly and we can tune the e-throttle target table. |
| 02:33 | This lets us adjust the target throttle opening based on foot pedal position and RPM. |
| 02:39 | This lets the power delivery of the engine and the feel of the throttle response to be adjusted to suit your preference. |
| 02:46 | If you want, you can also choose up to three separate throttle target tables and set a different throttle target response for each. |
