Torque (Android App)

[marka87uk]

Hey,

Just wondered if any of you use the Torque app for Android?

I have it with a cheap eBay adapter and managed to try it out some more today - I'm impressed by the results!

Previously I seemed to have a data rate problem but I've since changed the settings to log at 0.5s intervals and enabled faster logging to improve it. I think the data rate could be better if I had a more expensive adapter and better phone hardware, but it'll suffice for now!

Today I logged the RPM and MAF reading and did a 3rd gear run. Unfortunately I couldn't get to the point where it would change up because I ran out of road! 

I downloaded the log anyway and calculated the horsepower by the MAF reading /0.8, smoothed the HP reading by taking an average of the values below and above, and then calculated the torque by (HP/5252)*RPM.

Here are the results:



The book figures for the car are 221 lb/ft and 227 bhp!

I know the MAF calculation isn't entirely accurate, but the fact I achieved the expected HP shows that it should be a very accurate way of measuring any changes in performance!

I'd be interested to learn more about the app and what you use it for!

Nice one  

I'd seen it reviewed here:-

Only thing is that it doesn't seem to log the boost on VAG engines. Have you found that yourself?

Thought about having a play with it myself.

I haven't tried logging boost as I also heard that was a problem with VAG engines but I'll see if it can!

I tried logging horsepower calculated from within the app but it came up with no data - I'm guessing I haven't entered all of the settings correctly. I'd like to try to get that working to see how it differs from the MAF/0.8 calculation and also do a full log to peak RPM (I need to find a long road!).

More testing this week I think!

By the way, the adapter I have is the one pictured in the review you posted. I won it for the grand sum of £11 so it's definitely a very cheap method of diagnostics and OBD logging!

Nice one, keep us informed.

This seems amazing value.  Looking forward to hearing about the boost logging

I did some more logging today up to the point where the DSG changes up. The results are actually quite consistent!

I firstly did a 3rd gear run which showed a peak of 233bhp and 237lb/ft. I then did a 2nd gear run which showed a peak of 231bhp and 229lb/ft.

I've also since realised that to show the x-axis on the graph as a value instead of category (so that the RPM values are an equal distance apart) I needed to select an X-Y Scatter Chart in Excel, so here's the updated one:



I forgot about trying to log boost so I'll give that a go tomorrow!

[marka87uk]

I can confirm boost is not logged on my 2.0TFSI and it seems that's the case with most VAG engines!

Oh well, still enjoying messing about with it!

just digging up an old thread.

Im looking to download this app but not sure which Bluetooth adaptor to go for...
Has anybody got any links to one that is known to work properly?

Thanks guys

thanks Rich 

I presume he doesnt get issues with the App scanning the ECU etc?

thanks

[rich83]

Not as far as I know. Seems to clear faults ok and the bhp calculator worked mine out at about 280bhp so reasonably accurate.

thanks Rich,

i guess for a little over a tenner and try the free version of the app, its worth a go!

cheers
