Torque Software- Settings?

[f308gt4]

I just got my Torque software and Bluetooth adapter.

See this thread:
http://www.audizine.com/forum/showth...327-obdii-v1.4

Was wondering what you guys are using for settings:

Vehicle weight in kilograms?
Boost Adjustment?
Volumetric efficiency? (85?)

Any other settings I should know about?

Thanks!

[f308gt4]

Bump- What are you guys that are using Torque using for your settings?? I think it would be good to have a thread with this info to help others out.

Thanks!

[SykoraA4]

I still need to play around with it more... so far it reads my boost all kinds of crazy.

[CorneliusRox]

Figure this out so then you can give me your settings when I do this! lol

[f308gt4]

So nobody else is using this?

For now, I set:

vehicle weight (kg): 1544
boost adjustment: 0
Volumetric efficiency: 85

If anyone has suggestions/tips, would love to hear them.

Thanks!

I still am unclear what we should be using for VE. I have seen conflicting advice on this one-- anywhere from 85 to 95. If anyone knows a more definitive answer on this, I'd love to hear it with an explanation.

Just got this combo last night and all i can is this is awesome. Not sure how i can use this to troubleshoot the car. Codes can only be read if a CEL is triggered and don't know what useful widget to look at.

Also, has anyone here got the boost function to read correctly? I am getting a negative psi reading all the time and even at >3000rpm. Boost adjustment is set to -14.7,0 and 14.7 but, i still get the same negative boost reading.

[Sprode]

Unfortunately the VE is a moving target on a turbo engine... based on cams and dynamic compression. 85 to 90 is prolly a good number

Currently have volumetric efficiency set to 85.

You must find out your atmospheric pressure art your specific altitude in order to calibrate three boost function. You can probably get a fairly accurate number on google if you know your elevation. Or, a vag com can tell you exactly what it is.

For example, my car read atmosphere at 800 mbar. Multiply 14.7 x .8 and you get 11.76. That is the value you put in to get accurate boost. My car weighs 3800 lbs with me in it, divide that by 2.2 and you have your kilos. I work a3 a place with a truck scale. That's how I know. If you really want to know, find a landscape supply yard. They have truck scales, and won't charge you anything to put your car on and find out.

I always used land fill places. Usually you can take your garbage to the compactor for WAY cheaper and they weigh you before and after. My truck is just a hair under 8000lbs. I need to do my car soon. Full fluids. The internets say it is about 3300lbs wet, but that seems super low to me.



Also Chicago area is 1016 mbar (hPa), so 1.016*14.7=14.9352

[pkny]

So according to weather.com the pressure in my area is 30.2" so it should be roughly 14.8psi.
I'll enter this as a positive number on the boost adjustment and report back. I also noticed that my boost calculation is set to "MAP(preferred)" and should be set to "MAF". I'll change that to MAF, the software should of just used MAF anyways though.

As long as you are below 30psi I believe our MAF's are accurate. idk if it will be able to convert it to PSI for you though.

[CorneliusRox]

I dont have this software yet since my bluetooth OBD2 thing wont be here till the 19th. Little over a month for it to ship here...

[pkny]

^^^
I purposely searched for US sellers so i could get this faster. You know some of the China based vendors offer express shipping. Used express shipping for a USB mini charger and a retractable usb cord and got it in 6 business days.

Thanks for your help guys but, i am still having negative boost showing on my Torque gauge.

I know there should be a setting i am messing up but i just don't know what. Tomorrow i am going to uncheck the "Dont display psi as in/Hg" which shows in/Hg when in vacuum.

So far current settings are as follows:
Profile
-Engine Displacement= 2.0
-Weight=1655 kg
-Fuel Type=Petrol
-Boost Adjustment=14.83
-VE=85

Settings
-Fast communication "Enable"
-Boost calculation method "MAF"

[pkny]

Contacted the developer of the app and he said it should work
He suggested that "Boost adjustment" should be 0 and "Disable ELM327 auto timing adjustment" should be unchecked

Current settings

These are working settings for a B7 6speed A4 quattro avant. Sedans may want to subtract 100lbs from the weight.

I used your settings above. My torque works fine. which addapter did you get? I am using this one http://www.amazon.com/gp/product/B00...00_i00_details

Here is what I have so far setup to look at. Anything else specific to our cars should I be looking at...

Oh cool that is exactly what i have shown on my screen also haha.
I got this adapter http://www.amazon.com/Bluetooth-ELM-...1946450&sr=1-3
It is the same as yours i think.

So.....when you gun it, what is your MAF and Vacuum pressure reading at its highest point?

My is always reading vacuum and spikes at 3 psi, which makes me think i may have a MAF problem.

[funky_snowman]

nevermind

[pkny]

Alright....... the above settings in post#16 is correct for my car, 2006 audi a4 avant 6mt quattro, i am guess non-avant might want to subtract 100lbs from the weight.

Looks like i am just not loading the car enough from what vag-com is stating which is because i am not getting any boost. So, i should stop driving like a grandma.

[DarkHelmet]

i have not tested much since using your settings. But from memory my max boost was around +12. I have a 2006 a4 quattro. I sure would like to find a cheep 7 inch tablet to run this app on. If I run it on my phone with gps on, it still drains the battery when the phone is plugged into the charger

The volumetric efficiency of a turbo car is over 100%.
You can use VAGCOM to find it. It read a certain block where the ECU calculate it based on temperature and intake pressure. A stock turbo engine is around 125~150% VE.

On a Naturally aspirated engine, the VE of an Audi (mine as an example, 2.8L V6 30 valves) is ~95% at max torque, and ~84.2% at max hp.
The VE is variable true the whole RPM range.

[brucebanner]

so ive got mine all setup, however im not sure if the boost readings are proper, or maybe i just dont know how to read boost. anyone want to fill me in on what our cars should be reading? i have a stage 2 b7 a4. im using the settings as described on post 16.

On a third gear pull, you should be seeing a peak of anywhere from 18-21 tapering down to about 10 by redline.

jim my boost follows exactly what you are saying. I am curious though why people will say they peak at 21 and hold 18, it makes no sense to me.

[DarkHelmet]

The widget I used remembers the peak. I don't use torque all the time. Very rarely actually. Last Friday I got my ecu programmed APR. During the drive home my widget showed a peak of 22. using the settings from post #16 above.

[CorneliusRox]

Works for me. Works pretty good and my phone sites on the gauge pretty well.

I've seen some bad results setting VE over 100 for a turbo car. In reality, it is essentially experimentally/empirically determined. Trying to add VE is as a calculation when you are also predicting other things gives you too many unknowns with not enough equations.

If you were to log your boost and do a 3rd gear pull it would peak at about 3000 and then hold at 18psi from 3500 to redline.
That whole state of holding at 18psi may only last a couple of seconds also. Most of the time if your driving, the boost gauge should read negative if your not loading the engine.
The lower the boost reading the higher the MPG you would get regardless of RPM speeds.

You hold 18psi all the way to redline? My boost drops to around 10psi at redline like jimrobbington mentions above.

[jimrobbington]

I have never seen a stock turbo "hold" all the way to redline. I will "peak" 21-25 at about 3k, then it will drop to 18-21 and hold for maybe 1.5k at the most then retreat to 10 by redline

JR

[jimrobbington]

As you can see, your tuning does not even request a constant boost. Even the requested boost drops as rpms increase.

Sorry that is not what i meant to say. Wanted to say it would peak and hold around 18psi. Post #32 explains it all.

[the_ric]

How accurate is Torque? Currently running torque with the settings from post #16 and drive at about sea level. I bought the car used about a year ago and is supposed to be stock. I did some research and it looks like stock should be about 12-14 spike but it is currently showing about 20-21 spike.

[pkny]

the pressure around DC is also close to sea level and the above settings worked.

Have you tried hooking a vag-com and doing a log? Or you may not be stocked.

[airbornerifleman]

Regardless of RPM. really? Please explain.

Are you saying I can drive around at 3000RPM not boosting all day and I would burn the same amount of fuel if I was drive around at 2000RMP not boosting? BS!

[pkny]

Yes, yes that is possible.
I guess i shouldn't of made such a bold statement, but this was explained to me when i was interning at Cummins and i don't quite remember the theory. And someone reputable here did mention it in a post i read a while back
If the engine load was lower at the 3000rpm then you can be burning less fuel then driving around at 2000rpm, that is why i mentioned lower boost reading. Boost reading and engine load kinda go hand in hand.

So I should of said "the lower boost reading the higher the MPG you would get regardless of RPM speeds at the same velocity"

Thank you for correcting me.

This makes more sense ;)
