Hey just for fun I installed that app and decided to test it on my car and some other cars which were dynoed recetnly.

Here u can see my original dyno







And here you see the chart from the app. It shows 2 runs and the results on the left are at 6370rpm. Both runs around 160bhp. Also like the real results the torque peaks at around 4000-4100rpm.







After that close results we tested a friends BMW which was dynoed a week ago and again the app was f*cking close... only 3 bhp difference ?!?



Another friend used his G tech when he was on a drag strip and told me that the g tech is off by a 0.1 sec on 1/4 mile. So I took the g tech and my phone for a 400m run.

Gtech - 400m 15.16

Phone - 400m 15.38 @ 153.1 kmh ~ 95mph



Here is the results from that run







I was with another person in the car and the road was far from a drag strip so my 20m ( 66ft ) times are not the best

 

I have used the app Torque on my galaxy tab 3 in conjunction with a Bluetooth obd 2 dongle and it has ALWAYS been very close to actual Dyno results and rated power figures. That is as long as the parameters are set correctly. I think its pretty cool ****!

 

Yep I forgot to mention that you need to set correct parameters. Weight, speed at 1800rpm, speed at 6500rpm and so on...

 

Its good to see technology getting more accurate,but,I hope people don't start putting in false weights and stuff and start posting in track times fourms lol

 

Definitely!!

 

Those apps are for fun and will give you an idea of the performance of your car
