Boost Pressure
01.31
| 00:00 | - Since one of the common tuning tasks we're going to be performing is to increase boost pressure, monitoring boost is an obvious requirement. |
| 00:06 | Regardless whether you're using a standalone ECU or reflashing a factory ECU, boost pressure should be a parameter that you can view and log in your laptop, so long as boost pressure you're running is within the range of the factory sensor which is commonly limited out at 37 psi if you're operating at sea level. |
| 00:22 | Beyond this boost pressure, you'll need to wire in a sensor with more range, or rely on an analogue sensor. |
| 00:29 | Being able to log boost pressure is vital to the tuning process however it's also worth considering adding a secondary boost sensor that can give you a quick visual reference of boost pressure when the laptop isn't connected. |
| 00:39 | If you're planning to fit a boost gauge to your vehicle then I'm going to go out on a limb here and suggest an analogue gauge. |
| 00:45 | This will give you a moving needle compared to a digital version that simply gives you a numeric readout of your boost pressure. |
| 00:50 | This might seem a little like a step backwards in technology but the human brain actually responds better to a moving needle and it's much easier to see at a glance what the boost gauge is doing. |
| 01:00 | This is ideal and you'll often be just taking note of the boost gauge out of peripheral vision rather than needing to focus all your attention on it. |
| 01:06 | The downside of an analogue gauge is that you may only be able to use it for one purpose, whereas the gauges that interface with the OBD2 port will show a variety of important information in digital form simultaneously. |
| 01:18 | This does come down to personal preference and a digital gauge which offers a peak and hold display as well as a user adjustable warning level is going to be a great addition. |
