I would like to do this also. I think torque makes an app for Iphone. Would that work?

Im not sure whats up with the reviews, the first three are weird. Like they dont understand you actually need a scanner.
Not the same as Torque Pro for Android. The reviews looks sketchy.
Yeah I was just reading that, but it looks like they dont understand you actually need a scanner.

Can someone explain to me barometer pressure in relation to our Ranger and how to tell if something is not working correctly if barometer pressure is "so and so". Please :please:

Bluetooth OBD2 reader + OB2AA + torque pro.

Not going to lie, it was kind of a PITA to setup in my opinion. I just installed it so lets see how clunky it is in the long run. I'll be removing the decimal readings. On the plus side, the response is spot on. No lag between the bluetooth OBD and headunit.

Great thread,I added something else that is a Nice add on.

Should be nice to see what kind of boost it’s making under different loads and different situations.

Used the parts and pieces mentioned,and a glow shift pod mount,and was up and working in about an hour.

Very simple and straihgt forward.

I like this gauge better! But the other one looks good too!

:LOL:
Living in Az,knowing the air temp out of the vents is nice.
Although the A/C in these is good,it rarely blows colder than low 50’s out of the vents..
‘My Hellcat,and Jeep,blow low 40’s,with the Hellcat blowing right at 40.

May have a buddy check it just because.

Just find an used android phone to use. It doesn't need an active cell account to work.

Generally, barometric pressure will be used in compensation tables for boost, VE, etc. As you lose baro pressure, your turbo (particularly the small ones found on an OEM like this) will start running out of its efficiency island, so you may see boost go down at really high altitudes (same with excessive intake temps). You generally have comps for target boost as well as wastegate duty cycle. These can be manipulated based on the turbo size you run. If you put a fairly large turbo, you can sometimes command more boost at altitude, or even the same boost to keep the power losses down.

As for VE, pressure at the end of the exhaust goes down, so I generally see engines lean out at high altitudes (generally when going into the mountains... I live at 8k feet) if baro comp tables are zero'd out.

Very detailed. Thank you Jason, will look into some of this terminology.
