To Ian, or any one in the know:
I have a BMW F10 528xi, and am really suffering from the "ass dyno" indications of my car being under-powered. In order to check it, I've purchased the Torque Pro app and an ODB scanner - unfortunately, I just cannot configure the app (and/or my car Profile) so that the readings are realistic...
1. I entered the weight of my car as close as I only could, but still the WHP readings are too low (even compared to my "ass-dyno" - not to mention the factory specs).
2. My turbo boost readings are a complete mystery to me
3. Why is Torque Pro giving an indication of torque at the flywheel, but power - at wheels only? Do I need to use some secret formula to switch between the two?
4. With my car's 8-speed AT, which is the gear I should measure my top power/torque at? Should it be the 6th, at speeds exceeding 200 kmph? Or doesn't it matter at all?!!!
4. My 0-100 kmph acceleration times are really poor with Torque Pro - worse than the BMW specs for the 528xi. Why are they so much worse (longer time) than the simple and free Fastest Droid app is showing? The difference is really serious: 6.6 seconds from Torque Pro vs. 5.5 seconds from Fastest Droid (and mind you - I do have a 'power box' installed, supposed to add some 49 PS/90 Nm)
Please, please help me learn how to use the great app Torque Pro certainly is, so that it's a source of fun and satisfaction rather than frustration it causes now!
TIA
Piotr

Dear Friends,
If you find my questions too general (and hence difficult to address) - please oh please help me make them more specific by asking your own questions to me, and passing any valuable hints...
Do not left me without help!

Hi!
Most of your questions should be answered by this page on the wiki:

Thanks. The wiki says:
"Start from a slow rolling start (about 5 to 10mph) and accelerate until about 55mph. This will give you the most accurate peak value for your vehicle. If you spin the vehicle wheels then this will cause the figures to over-read."
Questions:
1. With 8-speed automatic transmission, which gear should be used (in manual mode) to accelerate up to the said 55 mph? Or should I leave it up to the AT?
2. I reckon I should accelerate with gas pedal in the floor?
That's for starters; TIA!

Dear Friends,
Could I once more ask you for help? The power/torque readings by Torque Pro are so much lower than the advertised values that either I'm doing something totally wrong, or my car is not up to spec. 🙁
For 0-100 time, does Torque Pro only rely on GPS or some ECU input as well? Will matching my Android smartphone with an external GPS receiver with 10 Hz refresh rate help?

Thanks for the link. The other discussion shows that I'm not the only one with such basic doubts about using Torque properly - I guess we're lacking some really good documentation.
It also rises further questions:
- is the WHP/CHP "guestimator" accurate? It seems like the tranny loss it shows is huge - larger than I'd expect
- does Torque Pro show Torque values also at the wheels, not crank? In the logs, HP is clearly described "at the wheels", but Torque is not. Would it be crank value - and if so, how is it derived (acceleration test like with HP, or some ECU data from OBD2)?

The wiki link states at the wheels.

Thanks, but I need to know for sure.
How can people rave about Torque Pro being an 'almost professional application" if something like this is not even known for sure? Yes the Wiki says "wheel" about both HP and TQ - but in the app, when you look at sensor names, the HP is explicitly stated 'at the wheels' why the torque is NOT 🙁

My sad observation is that Torque Pro and its support might have been great some time ago, but I'm a little late to the party. One of the most basic things like real Help pages are missing, having been replaced with the Wiki pages that are mostly empty...
Just please tell me: has Torque Pro ever had a complete and detailed help system?
Also, the Web Viewer is not responding for a couple of days now - is it some housekeeping, or has it just gone for good?
