Write-Up: Torque APP OBD2 Reader

I think there's an option to account for different tire size in the vehicle setup.

 

Do you use the 'Enhanced MPG calculation' option?

 

Figured out how to get the Roll and Pitch meters into a digital format.

 

I tried to replicate your display and couldn't get anywhere near that setup. Almost like the display was different dimensions or something.

I also need to find a way to get a MAP sensor that's bluetooth so I can display boost on the same screen. Someone needs to make one of those. That would be super sweet! Plumb it, wire it to 12v and then pair it. Easiest boost gauges install ever! Well, other than on cars that already have MAP like my Optima.

 

I changed the DPI to 160 to cram more stuff on a smaller screen. It's only a 3.7" 480x800 screen.

 

Ah, that makes more sense. My SGS4 has pretty high resolution so I figured I should be able to get the same gauges on mine. Nope.

 

Sub.
I purchased my Tacoma about 2 months ago, just got a OBDII reader the other day, and purchased the Torque Pro app, very cool stuff, haven't had much time yet to get a good setup yet, but some good ideas in this thread.

 

I don't have a supercharger (yet), but the vacuum gauge works on my truck, but I can't test for boost.

 

There is no MAP sensor from the factory and the app just reads whatever is available at the OBDII port so there's no way to add MAP sensor.

 

Is boost/vacuum not the same sensor?

 

Whatever 'vacuum' you're seeing isn't actual vacuum that the ECU/OBDII is seeing because there is no manifold pressure sensor or MAP. That's why there is no boost read by the ECU because there is no sensor for it so if there is no sensor there can be no readings available for the app to display.

 

Yeah looks like it's reading -12 psi when it should be reading around -18 at idle. My last car, which had an actual boost/vac gauge, read about -18psi as well. I wonder where it's getting it's data from....

 

Is your SGS4 rooted? If so, you could use an xposed module to manually change the DPI for Torque with affecting the rest of the phone.

 

Yeah it's rooted but not that important to me really. If I could get the sensors I wanted to display it would be more valuable but no boost makes it a novelty more than anything to me.

 

I've tested with it on and off and I don't seem to notice any difference. I leave it on.

 

Without it, it's a lot more generous on the MPGs I'm getting. No way I'm getting 20mpgs city after heavy 33's.

 

I need to set mine up again.. used to use it regularly, but replaced my phone since then.. and lost all the settings, displays, etc. need to dive deeper into the settings as well. would love an accurate MPG reading..

 

I've compared Torque with the enhanced calculation to what I logged with Fuelly. It's pretty close. Once in a while Torque seems to revert the MPG dial to the last reading before disconnect though.

 

Anyone have oil temperature working? Did you use custom PID?

Share some pictures of your setup

 

Can anyone tell me what I should change the obd speed multiplier to for larger diameter tires as it says, to help with correcting the Speedo in torque? Running 33 12.5 15's. I messed with the GPS and ecu difference, but it was screwy. Seemed way off. Plus when I came to a stop, GPS was saying I was still moving, and it was at the same difference it was showing while driving. (?)

Think I may need to change the mpg trim too but still tweaking everything. Also trying to figure out how much my truck weighs.. I guesstimated it is about 5600. Door sticker says 5100. With heavier tires and wheels, extra misc weight in truck like lights, me, gas, small gear in cubbies.. Sound about right? I think I might go to a weigh station just for the heck of it. I'm curious now. Plus I'm not sure how much it affects torque. Would be nice to have it spot on though.
