MAP / TPS Setup and Calibration
02.30
| 00:00 | - For our example here, we've wired a GM three bar manifold pressure sensor or MAP sensor to the analog voltage one input. |
| 00:08 | Setting this up is very easy. |
| 00:10 | If we access the ECU settings menu and click on analog inputs, we will see a list of all the analog inputs to the ECU. |
| 00:19 | Click AN volt one and the settings for this input will pop up. |
| 00:23 | By double clicking on the box here, a drop down menu will open, allowing the type of input to be selected. |
| 00:30 | In this case, we're going to double click on MAP sensor. |
| 00:34 | Now we need to choose a calibration to tell the ECU what sensor we're using. |
| 00:39 | Double click on MAP sensor type and choose the sensor from the drop down list. |
| 00:44 | In this case, we're going to scroll through and double click on GM three bar. |
| 00:48 | You will see a window pop up telling you to perform a MAP sensor calibration. |
| 00:53 | Click OK. |
| 00:55 | Now if we go up to the ECU controls menu, you can see we have an option here to perform a MAP sensor calibration. |
| 01:02 | This process matches the MAP sensor output to the current barometric pressure. |
| 01:07 | Click on this and the ECU will automatically calibrate the MAP sensor. |
| 01:12 | A box will pop up telling you that the calibration was successful. |
| 01:15 | Click OK to close the box. |
| 01:18 | Now we're going to move onto the throttle position sensor or TPS which is wired to analog volt two. |
| 01:25 | Following the same method we used for the MAP sensor, we can select AN volt two from the drop down menu. |
| 01:31 | Select TPS main. |
| 01:33 | TPS sub is for engines equipped with electronic throttle bodies so we don't need to worry about this. |
| 01:40 | Once we have set up the input as a TPS, we need to perform a calibration. |
| 01:44 | We do this from the same drop down menu where we did the MAP sensor calibration. |
| 01:49 | Select TPS setup and follow the on screen instructions. |
| 01:53 | First you need to go to full throttle and press enter then closed throttle and press enter. |
| 01:58 | Once you've calibrated the TPS, I like to check that it is spanning smoothly and correctly by watching the bar graph display as you move your foot through the TPS travel. |
| 02:09 | Once we've configured any analog voltage inputs, we can confirm they are working and reading correctly by pressing R to bring up the run time values display. |
| 02:18 | We can view the inputs we have just configured in the analog tab and make sure they are displaying sensible values. |
