hey man loving the Tutorial but you lost me on Barometric Pressure bro
hold on a second, no one expects us to go all
Neil deGrasse Tyson here, all we are going to do is look for two things with that Channel:
1. Check does it simply have a value, in other words is it even working? is it plugged in? if it shows all zeros we may have a problem, that type of thing
2. Check does its reading match the one on our iPhone in the Weather app, see where it says Pressure? That's the pressure in your area, that should match.
and keep in mind you're not going to check this every single time you fire up your truck, no, this is just once in a while when you want to troubleshoot an issue, or tune something on your rig, it's just good practice to ensure your MAP sensor is working properly that's all
