It's not "Torque" that gets vacuum. Torque is just reading the vacuum information that the ECU is sending...
A better question would be "where is the ECU getting vacuum from".

The weird thing is that if you change the engine size, it changes what the vacuum guage displays on the screen. Having the displacement at 2.6, and it seems to do pretty well. It does creep into positive pressure a little, 1-2 psi at high rpm. I was messing around with it the other day, and put the displacement to 3.9, and it wouldn't go above 11in vacuum. Just for fun, I put it to 1.3. I got to 10 PSI boost at very low throttle. Haha!
So I'm wondering how close the 2.6 engine size is, and if we actually do get positive pressure in the intake manifold at times. I know Mazda designed the intake tract to have pulse tuning....

Sounds to me like the torque app is broken.
Surely if the ecu was able to poll a vacuum sensor that Cobb would have also accessed that information as well for the AP.
Where's oltmann to dive into the ecu for us and let us know.
I gotta learn how he does that ****.
Edit
And in all my years hanging around this place and taking Jeff's webinars I've never once heard anything about an OEM vacuum sensor. Just saying.
Maybe the Torque app is reading the wrong PID.
Or maybe its creating a virtual vacuum by using several different values ... like the engine displacement and the RPM alone with the G/S value? <shrug>
In the end ... sounds broken, I'll continue to trust my Cobb AP over this solution.

Mazmart Shopping Cart
Mazmart is selling used Boost/MAP sensor! How is that?
Edit: Corrected MAF to MAP...not sure why I typed MAF..

I was thinking geriatric
In all seriousness... I'm actually a little confused... Imagine that! But I get your point now, Beodude!!! I just had to look at the actual link.
That is indeed the barometric sensor!

This is a Boost/MAP (Manifold Absolute Pressure) Sensor that will fit 04-08 RX8 models. Located on bracket with Air Pump.
That is indeed the barometric sensor!

It's slightly mislabeled. That is basically a barometer. It is used to measure the ambient barometric pressure which is then used on a number of different tables for adjusting air/fuel ratios.
It is NOT a MAP. A MAP reports irrespective of atmospheric pressure and is plugged into your intake manifold. That sensor is open to atmosphere.

I have an issue with torque, the free version to just see how it works for now.
I tried putting in the PID,s listed in this thread but I get an error for an invalid equation, it doesnt seem to like the equations for STFT, LTFT, and cat temp. I'm guessing its just an issue with the free version but wanted to check before I paid for the app.

Yes, the paid version is well worth the money. After the money spent on the phone/tablet and the adapter, $5 is peanuts to make full use of everything. The license is attached to your google account, so you can share it between devices if you have more than 1. I even bought a 2nd license for my wife, just so she could pull data if she ran into a problem without me there.

If you think the free is good, wait till you get the paid one. If the free one is like taking a fun on-ramp, then the paid one is like a full track day at the Nurburgring. I had to use the free one temporarily a month or so ago, and felt massively handicapped. SOOO much more you can do with the paid. Make graphs, run more logs, faster response, plug ins, actual menu to use, code interface is far cleaner and allows for way more information (freeze frame, code lookup), mapping links, more PIDs already set to watch for (more than any 1 car will have), more gauge types, etc...

Hi
Can any one give me some help on how to get the Torque app to display air fuel ratio.
I see there is some equations on page one. but I have no idea what they mean.
Is there any instructions on how to do this in language that non tech savy people like me will understand?
