Yes, Torque shows lower mpg, than it is. You have to adjust it manually.

 

Do you have any data to support this?

I've used TP to track my FJ's fuel consumption for the last 9 years, and I've found that it is generally it is very close (within a few tenths of a MPG) to the pencil-and-paper calculation of odometer reading divided by gallons of fuel required to refill the tank.

In my experience, in some cases the TP value is slightly less than the calculated value, in some cases slightly more. I'm running stock tire diameter, so the odometer reading is pretty close to actual distance traveled. If you've got other than stock tire diameter, you need to include a correction factor or your MPG calculation will be inaccurate.

I don't think I made any 'adjustments' to the basic TP fuel consumption formula, although TP has provisions to do so.

 

This is how I track my mileage. " Does it suck as usual or does it suck more than usual" Its usually one or the other

 

I haven't had much luck with it either. Following

 

I've been using the free version of torque pro for years and I thought it was the best one out there. Since getting my FJ a few months ago I've discovered Car Scanner. Mainly because I wanted a transmission temp, which I haven't been able to get with the free version of torque pro. The gas milage seems to be very close on car scanner as well. So far I'm really liking it. As a bonus there is a coding feature in car scanner that allows you to shut off the seatbelt ding. Which is super useful for me when off-roading.

Thanks... I'll check that out.

 

Update... it seems that Car Scanner only supports wireless. I'm using a wired OBD connector as I find the wireless ones to be really unreliable with Android head units, if you can even find one that works. I'll have to stick with Torque Pro.

 

I've run Torque Pro continuously for over 60K miles in my '14, displaying Long Term Average, Instantaneous, and Trip MPG data.

With my vehicle, the TP data is extremely accurate when compared to calculating MPG via actual fuel burned (from gas station receipt and odometer miles traveled). If there is a slight difference, it's usually TP indicating a very slightly LESS than actual MPG (by 0.1 or 0.2 MPG). I am running stock tire diameter.

If you find that the TP's calculated MPG does not accurately match your distance traveled/fuel burned, TP does have provision for a 'correction factor' that you can adjust to improve accuracy.

 

Good to know... What settings are you using for things like volumetric efficiency, fuel type, and correction factor?

 

Does anyone know the OBDII version on a 2009? I'm setting up the car scanner app now and not sure which to select. There's the basic OBD-II/EOBD, and a few others that might be the correct one: "OBD-II/EOBD K-line/KWP + extra sensors," and "2006-2009 OBD-II/EOBD + CAN bus."

 

I used the one that included my year model, 2014, and it seems to work fine.

 

Original setup was years ago, but I know I made no changes to the default values for VE and MPG correction factor.

Fuel was just 89 octane gasoline as far as I remember ... I can check later today.

I don't believe that VE or fuel type have any influence on calculated MPG, which should be simply fuel consumed & distance driven, unless you have entered a fuel consumption correction factor.

I initially set up TP to monitor instantaneous MPG so I could minimize fuel burn and watch transmission temperature. After I got familiar with the ap, I added multiple gauges that allowed me to monitor interesting engine parameters like ignition timing advance, actual coolant temperature, throttle position, intake air volume, and both transmission pan and torque converter outlet temperature.

Here's what I currently display. This photo is immediately after engine shutdown, trans temperatures have been subsequently been reduced by ~30 degrees after installing an aux trans cooler. Because engine is not running, commanded and measured air fuel ratios (AFR) are not in synch, typically they are 14.X and are within about 0.2 of each other.

Thanks would be very interested to know what you have for volumetric efficiency, fuel type, and any correction factor settings.
